FTP

Introduction

The functions in this extension implement client access to files servers speaking the File Transfer Protocol (FTP) as defined in » https://datatracker.ietf.org/doc/html/rfc959. This extension is meant for detailed access to an FTP server providing a wide range of control to the executing script. If you only wish to read from or write to a file on an FTP server, consider using the ftp:// wrapper with the filesystem functions which provide a simpler and more intuitive interface.

For those who dont want to deal with handling the connection once created, here is a simple class that allows you to call any ftp function as if it were an extended method.  It automatically puts the ftp connection into the first argument slot (as all ftp functions require).

This code is php 5.3+

<?php
class ftp{
    public $conn;

    public function __construct($url){
        $this->conn = ftp_connect($url);
    }
    
    public function __call($func,$a){
        if(strstr($func,'ftp_') !== false && function_exists($func)){
            array_unshift($a,$this->conn);
            return call_user_func_array($func,$a);
        }else{
            // replace with your own error handler.
            die("$func is not a valid FTP function");
        }
    }
}

// Example
$ftp = new ftp('ftp.example.com');
$ftp->ftp_login('username','password');
var_dump($ftp->ftp_nlist());
?>

Upload file to server via ftp.

<?php
$ftp_server="";
 $ftp_user_name="";
 $ftp_user_pass="";
 $file = "";//tobe uploaded
 $remote_file = "";

 // set up basic connection
 $conn_id = ftp_connect($ftp_server);

 // login with username and password
 $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

 // upload a file
 if (ftp_put($conn_id, $remote_file, $file, FTP_ASCII)) {
    echo "successfully uploaded $file\n";
    exit;
 } else {
    echo "There was a problem while uploading $file\n";
    exit;
    }
 // close the connection
 ftp_close($conn_id);
?>
