parse_str

(PHP 4, PHP 5, PHP 7, PHP 8)

parse_str — Parses the string into variables

Description

parse_str(string $string, array &$result): void

Parses string as if it were the query string passed via a URL and sets variables in the current scope (or in the array if result is provided).

Parameters

string: The input string.
result: If the second parameter result is present, variables are stored in this variable as array elements instead.

Warning
Using this function without the result parameter is highly DISCOURAGED and DEPRECATED as of PHP 7.2. As of PHP 8.0.0, the result parameter is mandatory.

Return Values

No value is returned.

Changelog

Version	Description
8.0.0	`result` is no longer optional.
7.2.0	Usage of parse_str() without a second parameter now emits an `E_DEPRECATED` notice.

Examples

Example #1 Using parse_str()

<?php
$str = "first=value&arr[]=foo+bar&arr[]=baz";

// Recommended
parse_str($str, $output);
echo $output['first'];  // value
echo $output['arr'][0]; // foo bar
echo $output['arr'][1]; // baz

// DISCOURAGED
parse_str($str);
echo $first;  // value
echo $arr[0]; // foo bar
echo $arr[1]; // baz
?>

Because variables in PHP can't have dots and spaces in their names, those are converted to underscores. Same applies to naming of respective key names in case of using this function with result parameter.

Example #2 parse_str() name mangling

<?php
parse_str("My Value=Something");
echo $My_Value; // Something

parse_str("My Value=Something", $output);
echo $output['My_Value']; // Something
?>

Notes

Note:
All variables created (or values returned into array if second parameter is set) are already urldecode()d.

Note:
To get the current QUERY_STRING, you may use the variable $_SERVER['QUERY_STRING']. Also, you may want to read the section on variables from external sources.

It bears mentioning that the parse_str builtin does NOT process a query string in the CGI standard way, when it comes to duplicate fields.  If multiple fields of the same name exist in a query string, every other web processing language would read them into an array, but PHP silently overwrites them:

<?php
# silently fails to handle multiple values
parse_str('foo=1&foo=2&foo=3');

# the above produces:
$foo = array('foo' => '3');
?>

Instead, PHP uses a non-standards compliant practice of including brackets in fieldnames to achieve the same effect.

<?php
# bizarre php-specific behavior
parse_str('foo[]=1&foo[]=2&foo[]=3');

# the above produces:
$foo = array('foo' => array('1', '2', '3') );
?>

This can be confusing for anyone who's used to the CGI standard, so keep it in mind.  As an alternative, I use a "proper" querystring parser function:

<?php
function proper_parse_str($str) {
  # result array
  $arr = array();

  # split on outer delimiter
  $pairs = explode('&', $str);

  # loop through each pair
  foreach ($pairs as $i) {
    # split into name and value
    list($name,$value) = explode('=', $i, 2);
    
    # if name already exists
    if( isset($arr[$name]) ) {
      # stick multiple values into an array
      if( is_array($arr[$name]) ) {
        $arr[$name][] = $value;
      }
      else {
        $arr[$name] = array($arr[$name], $value);
      }
    }
    # otherwise, simply stick it in a scalar
    else {
      $arr[$name] = $value;
    }
  }

  # return result array
  return $arr;
}

$query = proper_parse_str($_SERVER['QUERY_STRING']);
?>

If you need the key names preserved and don't want spaces or . or unmatched [ or ] replaced by an underscore, yet you want all the other goodies of parse_str(), like turning matched [] into array elements, you can use this code as a base for that.

<?php
const periodPlaceholder = 'QQleQPunT';
const spacePlaceholder = 'QQleQSpaTIE';

function parse_str_clean($querystr): array {
    // without the converting of spaces and dots etc to underscores.
    $qquerystr = str_ireplace(['.','%2E','+',' ','%20'], [periodPlaceholder,periodPlaceholder,spacePlaceholder,spacePlaceholder,spacePlaceholder], $querystr);
    $arr = null ; parse_str($qquerystr, $arr);

    sanitizeKeys($arr, $querystr);
    return $arr;
}

function sanitizeKeys(&$arr, $querystr) {
    foreach($arr as $key=>$val) {
        // restore values to original
        $newval = $val ;
        if ( is_string($val)) {
            $newval = str_replace([periodPlaceholder,spacePlaceholder], ["."," "], $val);
        }

        $newkey = str_replace([periodPlaceholder,spacePlaceholder], ["."," "], $key);
        
        if ( str_contains($newkey, '_') ) { 

            // periode of space or [ or ] converted to _. Restore with querystring
            $regex = '/&('.str_replace('_', '[ \.\[\]]', preg_quote($newkey, '/')).')=/';
            $matches = null ;
            if ( preg_match_all($regex, "&".urldecode($querystr), $matches) ) {

                if ( count(array_unique($matches[1])) === 1 && $key != $matches[1][0] ) {
                    $newkey = $matches[1][0] ;
                }
            }
        }
        if ( $newkey != $key ) {
            unset($arr[$key]);
            $arr[$newkey] = $newval ;
        } elseif( $val != $newval ) 
            $arr[$key] = $newval;

        if ( is_array($val)) {
            sanitizeKeys($arr[$newkey], $querystr);
        }
    }
}

?>

For example:

parse_str_clean("code.1=printr%28hahaha&code 1=448044&test.mijn%5B%5D%5B2%5D=test%20Roemer&test%5Bmijn=test%202e%20Roemer");

Produces:

array(4) {
  ["code.1"]=>
  string(13) "printr(hahaha"
  ["code 1"]=>
  string(6) "448044"
  ["test.mijn"]=>
  array(1) {
    [0]=>
    array(1) {
      [2]=>
      string(11) "test Roemer"
    }
  }
  ["test[mijn"]=>
  string(14) "test 2e Roemer"
}

Whereas if you feed the same querystring to parse_str, you will get

array(2) {
  ["code_1"]=>
  string(6) "448044"
  ["test_mijn"]=>
  string(14) "test 2e Roemer"
}

That's not says in the description but max_input_vars directive affects this function. If there are more input variables on the string than specified by this directive, an E_WARNING is issued, and further input variables are truncated from the request.

This is probably a better solution than below. The first line makes sure the file doesn't exist then the second line directs all requests to a script. No need to output a 200 header with this method either.

Vladimir: the function is OK in how it deals with &amp;.
&amp; must only be used when outputing URLs in HTML/XML data.
You should ask yourself why you have &amp; in your URL when you give it to parse_str.

Tore Bj?lseth ¶

As of PHP 5, you can do the exact opposite with http_build_query(). Just remember to use the optional array output parameter.

This is a very useful combination if you want to re-use a search string url, but also slightly modify it:

Example:
<?
$url1 = "action=search&interest[]=sports&interest[]=music&sort=id";
$str = parse_str($url1, $output);

// Modifying criteria:
$output['sort'] = "interest";

$url2 = http_build_query($output);

echo "<br>url1: ".$url1;
echo "<br>url2: ".$url2;
?>

Results in:
url1: action=search&interest[]=sports&interest[]=music&sort=id
url2: action=search&interest[0]=sports&interest[1]=music&sort=interest

(Array indexes are automatically created.)

just a heads up with the example above:
?var[]=123 - the [] has to be urlencoded.
var names and var values - both have to be urlencoded!

If you are trying to preserve a complex array, the function serialize might be better than http_build_query or other methods of making a query string.

Well, it would be - it's not supposed to be passed html entities, that's a different encoding scheme. This function does correctly decode url encoded params for you though (with the rawurlencode rather than urlencode, ie '+' is translated to a space).

The array to be populated does not need to be defined before calling the function:

CONVERT ANY FORMATTED STRING INTO VARIABLES

I developed a online payment solution for credit cards using a merchant, and this merchant returns me an answer of the state of the transaction like this:

estado=1,txnid=5555444-8454445-4455554,monto=100.00

to have all that data into variables could be fine for me! so i use str_replace(), the problem is this function recognizes each group of variables with the & character... and i have  comma separated values... so i replace comma with &

<?php
$string = "estado=1,txnid=5555444-8454445-4455554,monto=100.00";
$string = str_replace(",","&",$string);
parse_str($string);
echo $monto; // outputs 100.00

Note that the characters "." and " " (empty space) will be converted to "_". The characters "[" and "]" have special meaning: They represent arrays but there seems to be some weird behaviour, which I don't really understand:

<?php
// Note: "[" = %5B, "]" = %5D

/*
"v][=a" produces ("[" gets replaced by "_"):
Array
(
    [v]_] => a
)
*/
parse_str("v%5D%5B=a", $r);
print_r($r);

/*
"v][[=a" produces (first "[" gets replaced by "_", but not all following):
Array
(
    [v]_[] => a
)
*/
parse_str("v%5D%5B%5B=a", $r);
print_r($r);

Here is a little function that does the opposite of the parse_str function. It will take an array and build a query string from it.

<?php

 * @return  string              : Query string to append to a URL.
 * @param   array    $array     : Array of parameters to append to the query string.
 * @param   string   $parent    : This should be left blank (it is used internally by the function).
 */
function append_params($array, $parent='')
{
    $params = array();
    foreach ($array as $k => $v)
    {
        if (is_array($v))
            $params[] = append_params($v, (empty($parent) ? urlencode($k) : $parent . '[' . urlencode($k) . ']'));
        else
            $params[] = (!empty($parent) ? $parent . '[' . urlencode($k) . ']' : urlencode($k)) . '=' . urlencode($v);
    }

    $sessid = session_id();
    if (!empty($parent) || empty($sessid))
        return implode('&', $params);

    // Append the session ID to the query string if we have to.
    $sessname = session_name();
    if (ini_get('session.use_cookies'))
    {
        if (!ini_get('session.use_only_cookies') && (!isset($_COOKIE[$sessname]) || ($_COOKIE[$sessname] != $sessid)))
            $params[] = $sessname . '=' . urlencode($sessid);
    }
    elseif (!ini_get('session.use_only_cookies'))
        $params[] = $sessname . '=' . urlencode($sessid);

    return implode('&', $params);
}

?>

Note that the function will also append the session ID to the query string if it needs to be.

I shouldn't've posted the original version, as it only worked with the most basic of query strings.

This function will parse an html-safe query-like url string for variables and php-like ordered and associative arrays.  It places them into the global scope as parse_str does and adds minimal slashes for database insertions without the triple-slash problems that magic quotes can produce (the reason I had to write it in the first place).  If you don't need the slashes, they're easy enough to remove.

<?php
function parse_query($str) {
    
    // Separate all name-value pairs
    $pairs = explode('&', $str);

If you wish a version of parse_str sans magic quotes, the following will do the trick:

<?php
function parse_query($str) {
    $pairs = explode('&', $str);

    foreach($pairs as $pair) {
        list($name, $value) = explode('=', $pair, 2);
        global $$name;
        $$name = $value;
    }
}
?>

In Kent's solution you may wish to switch "urldecode" into "rawurldecode" if you'd like to get rid of the [annoying] plus '+' converted to space ' ' translation.

Warning: `parse_str()` can cause "Input variables exceeded 1000" error (1000 is default php.ini setting for `max_input_vars`).

Test code.

<?php

$inputString = 'first=firstvalue';

for ($i = 1; $i <= 1100; $i++) {
    $inputString .= '&arrLoopNumber[]=' . $i;
}
unset($i);

echo 'input string: <code>' . $inputString . '</code><br>' . PHP_EOL;
echo '<h5>doing <code>parse_str()</code></h5>' . PHP_EOL;

$output = [];
parse_str($inputString, $output);
// errors!!
?>

proper_parse_str works great and I like that it doesn't replace spaces with underbars, but should urldecode $value

If you need a function that does something similar to parse_str, but doesn't convert spaces and dots to underscores, try something like the following:



<?php

function parseQueryString($str) {

    $op = array();

    $pairs = explode("&", $str);

    foreach ($pairs as $pair) {

        list($k, $v) = array_map("urldecode", explode("=", $pair));

        $op[$k] = $v;

    }

    return $op;

}

?>



It may need adapting to handle various edge cases.

When you have scripts run through the command-line (like locally via cron), you might want to be able to use _GET and _POST vars. Put this in top of your scheduled task files:

<?
    parse_str ($_SERVER['argv'][1], $GLOBALS['_GET']);
    parse_str ($_SERVER['argv'][2], $GLOBALS['_POST']);
?>

And call your script by:

/usr/local/bin/php /path/to/script.php "id=45&action=delete" "formsubmitted=true"

Cheers!

Vladimir Kornea:
Try use html_entity_decode()

$str = 'first=value&amp;arr[]=foo+bar&amp;arr[]=baz';
parse_str(html_entity_decode($str), $output);
print_r($output);

Array
(
    [first] => value
    [arr] => Array
        (
            [0] => foo bar
            [1] => baz
        )

if you would like to get a nice url scheme with php/apache and and want to handle all requests in a central php script there's a simple solution/hack:

create a .htaccess in your "basedir" where you've got your main script (in this example index.php) containing some lines like:

"ErrorDocument 404 /index.php"

inside index.php you can now do

<?php
    $virtual_path = substr(
        $_SERVER['REQUEST_URI'],
        strlen( dirname( $_SERVER['PHP_SELF'] ) ) + 1
    );
    if( ($pos = strpos( $virtual_path, '?' )) !== false ) {
        parse_str( substr( $virtual_path, $pos + 1 ), $_GET );
        $_REQUEST = array_merge( $_REQUEST, $_GET );
        $virtual_path = substr( $virtual_path, 0, $pos );
    }

    // some code checking for a valid location, etc...
    header( 'HTTP/1.1 200 OK' );
    header( 'Content-Type: text/plain' );

    echo $virtual_path."\n\n";
    print_r( $_REQUEST );
?>

This does not work as expected.

<?php
class someclass
{
    var $query_string;
    function someclass($a_query_string)
    {
        $this->query_string = $a_query_string;
        parse_str($this->query_string);
    }
    function output()
    {
        echo $this->action;
    }
}

$a_class = new someclass("action=go");
$a_class->output();
?>

Use this instead.

<?php
class someclass
{
    var $arr;
    function someclass($a_query_string)
    {
        parse_str($a_query_string, $this->arr);
    }
    function output()
    {
        echo $this->arr['action'];
    }
}

$a_class = new someclass("action=go");
$a_class->output();
?>

Beware using parse_str in a function that has vars passed by reference. It seems that parse_str actually creates new vars even if vars of the same name exist. If you pass by ref vars of the same name as those in a query string being parsed new LOCAL vers will be created and you won't get any values passed back to the caller (relates to what Maikel mentioned below)

An unrealistic example (vaguely related to what I was doing when I found this out)...

function get_title($query,&$title)
{
  parse_str($query);
  $title=str_replace("_"," ",$title);
}

$title="foo";
$query = "context=something&title=Title_of_Something";
get_title($query,$title);

echo $title .... "foo"

parse_str() is confused by ampersands (&) being encoded as HTML entities (&amp;). This is relevant if you're extracting your query string from an HTML page (scraping). The solution is to run the string through html_entity_decode() before running it through parse_str().

(Editors: my original comment was a caution whose solution is obvious, but it has resulted in three replies ("so what?" "as intended" and "this is how to fix it"). Please remove the previous four posts dealing with this (69529, 70234, 72745, 74818) and leave just the above summary. This issue is too trivial to warrant the number of comments it has received.)

I wrote a pair of functions using parse_str() that will write values in an array to a textfile and vice versa, read those values from the textfile back into the array. Quite useful if you need to store lots of data but don't have access to SQL.

Save the array by calling cfg_save($filename,$array) and load it back using $array=cfg_load($filename)

<?php
$newline="?";

function cfg_load($cfgfile){
    global $newline;
    $setting="";
    if(file_exists($cfgfile)){
        $setting=fopen($cfgfile, "r");
        $ookk="";
        while($ook=fgets($setting)){
            #strip comment
            $commt=strpos($ook,"##");
            if($commt!==false) $ook=substr($ook,0,$commt);
            #append
            if($ook!="") $ookk=$ookk."&".    str_replace($newline,"\n",str_replace("&","%26",trim($ook)));
        }    
        fclose($setting);    
        parse_str($ookk, $setting);
    }
    return $setting;
}

function cfg_save($cfgfile,$setting){
    global $intArray;
    $intArray="";
    for($i=0;$i<2000;$i++)
        $intArray[]=$i;
    if(is_array($setting)){
        $allkeys=array_keys($setting);
        foreach($allkeys as $aKey)
            cfg_recurse($setting[$aKey], $aKey, $outArray);
    }
    $cfgf=fopen($cfgfile,"w");
    foreach($outArray as $aLine)
        fputs($cfgf,stripslashes($aLine)."\r\n");
    fclose($cfgf);
}

function cfg_recurse($stuffIn, $keysofar, &$toAppend){
    global $intArray, $newline;
    if(is_array($stuffIn)){
        $allkeys=array_keys($stuffIn);
        if(array_slice($intArray,0,sizeof($allkeys))==$allkeys)
            $nokey=true;
        else 
            $nokey=false;
        foreach($allkeys as $aKey){
            if(!$nokey) $toKey=$aKey;    
            cfg_recurse($stuffIn[$aKey], $keysofar."[".$toKey."]", $toAppend);
        }
    }else
        $toAppend[]=$keysofar."=".str_replace("\n",$newline,$stuffIn);
}
?>

Note that these functions support nested arrays of unlimited levels ;)

function like parse_str, but doesn't convert spaces and dots to underscores in $_GET AND $_POST

/**
 * GET and POST input containing dots, etc.
 */
function getRealREQUEST() {
    $vars = array();

    $input    = $_SERVER['REDIRECT_QUERY_STRING'];
    if(!empty($input)){
        $pairs    = explode("&", $input);
        foreach ($pairs     as $pair) {
            $nv                = explode("=", $pair);

        }
    }
    
    $input    = file_get_contents("php://input");
    if(!empty($input)){
        $pairs    = explode("&", $input);
        foreach ($pairs as $pair) {
            $nv                = explode("=", $pair);
            
            $name            = urldecode($nv[0]);
