The `MYSQLI_OPT_SSL_VERIFY_SERVER_CERT` seems to always fail, with `options()` always returning false.
Use the `MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT` flag with `real_connect()` instead.

mysqli::options -- mysqli_options — Set options
Nesne yönelimli kullanım
Yordamsal kullanım
Used to set extra connect options and affect behavior for a connection.
This function may be called multiple times to set several options.
mysqli_options() should be called after mysqli_init() and before mysqli_real_connect().
bağlantıSadece yordamsal tarz: mysqli_connect() veya mysqli_init() işlevinden dönen bir mysqli nesnesi.
optionThe option that you want to set. It can be one of the following values:
| Name | Description |
|---|---|
MYSQLI_OPT_CONNECT_TIMEOUT |
Connection timeout in seconds |
MYSQLI_OPT_READ_TIMEOUT |
Command execution result timeout in seconds. Available as of PHP 7.2.0. |
MYSQLI_OPT_LOCAL_INFILE |
Enable/disable use of LOAD LOCAL INFILE |
MYSQLI_INIT_COMMAND |
Command to execute after when connecting to MySQL server |
MYSQLI_SET_CHARSET_NAME |
The charset to be set as default. |
MYSQLI_READ_DEFAULT_FILE |
Read options from named option file instead of my.cnf Not supported by mysqlnd. |
MYSQLI_READ_DEFAULT_GROUP |
Read options from the named group from my.cnf
or the file specified with MYSQL_READ_DEFAULT_FILE.
Not supported by mysqlnd.
|
MYSQLI_SERVER_PUBLIC_KEY |
RSA public key file used with the SHA-256 based authentication. |
MYSQLI_OPT_NET_CMD_BUFFER_SIZE |
The size of the internal command/network buffer. Only valid for mysqlnd. |
MYSQLI_OPT_NET_READ_BUFFER_SIZE |
Maximum read chunk size in bytes when reading the body of a MySQL command packet. Only valid for mysqlnd. |
MYSQLI_OPT_INT_AND_FLOAT_NATIVE |
Convert integer and float columns back to PHP numbers when using non-prepared statements. Only valid for mysqlnd. |
MYSQLI_OPT_SSL_VERIFY_SERVER_CERT |
Whether to verify server certificate or not. |
valueThe value for the option.
Eğer mysqli hata bildirimi etkinse (MYSQLI_REPORT_ERROR)
ve istenen işlem başarısız olursa bir uyarı üretilir. Ek olarak, kip
MYSQLI_REPORT_STRICT ise bunun yerine
mysqli_sql_exception istisnası oluşur.
Bilginize:
MySQLnd daima sunucunun öntanımlı bir karakter kümesi olduğunu varsayar. Bu karakter kümesi, mysqlnd'nin kullanacağı uzlaşım/kimlik doğrulama bağlantısı sırasında gönderilir.
Libmysqlclient, ya my.cnf dosyasındaki öntanımlı karakter kümesini ya da mysqli_init() çağrısından sonraki ilk mysqli_real_connect() çağrısından önce çağrılan mysqli_options() işlevinde belirtilen karakter kümesini kullanır.
The `MYSQLI_OPT_SSL_VERIFY_SERVER_CERT` seems to always fail, with `options()` always returning false.
Use the `MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT` flag with `real_connect()` instead.There is an undocumented option: MYSQLI_OPT_READ_TIMEOUT. This is similar to MYSQLI_OPT_CONNECT_TIMEOUT in theory, but has a slightly different application. Connection timeout only specifies the wait time for the initial TCP connection. Once that is created, the timeout no longer applies. Read timeout, however, is from the time the TCP connection is created until the first packet of actual data is received. There are instances where a TCP connection can be established, but the MySQL server stalls indefinitely, preventing execution from ever returning to PHP. Specifying a read timeout alleviates this condition, whereas connect timeout wouldn't.
If the MYSQLI_OPT_READ_TIMEOUT constant isn't defined, it is still supported on versions where that isn't the case. You can define it yourself in older PHP versions with the following code.
<?php
if (!defined('MYSQLI_OPT_READ_TIMEOUT')) {
define ('MYSQLI_OPT_READ_TIMEOUT', 11);
}
?>
You can then use read timeout the same way you could a connect timeout as follows. Please note that since these are two different timeout values for two different parts of the entire connection process, the timeouts do stack (eg: 10 seconds connect timeout + 10 seconds read timeout = maximum possible timeout of 20 seconds)
<?php
//create the object
$connection = mysqli_init();
//specify the connection timeout
$connection->options(MYSQLI_OPT_CONNECT_TIMEOUT, 10);
//specify the read timeout
$connection->options(MYSQLI_OPT_READ_TIMEOUT, 10);
//initiate the connection to the server, using both previously specified timeouts
$connection->real_connect('server', 'user', 'pass', 'database');
?>Here es little example to create a SSL Connection
<?php
$db = mysqli_init();
/*
When you want so use a separate cnf
$test = $db->options(MYSQLI_EAD_DEFAULT_FILE,'myother.cnf');
*/
$db->ssl_set('server-key.pem','server-cert.pem',
'cacert.pem',NULL,NULL);
$db->real_connect('localhost','root','','mydb');
//Here some query
$db->close();
?>With Objective Approach
init of mysqli is depreciated from 8.1 it seem so
You could have to use an empty __construct()
So You have proper int and float
class DB extends \mysqli {
private function __construct(
private $_user = DBUSER,
private $_pass = DBPWD,
private $_dbName = DBNAME,
private $_dbHost = DBHOST,
) {
parent::__construct();
parent::options(MYSQLI_OPT_INT_AND_FLOAT_NATIVE, 1);
parent::real_connect($this->_dbHost, $this->_user, $this->_pass, $this->_dbName);
}
}Although it is not explained on the manual, MYSQLI_OPT_SSL_VERIFY_SERVER_CERT is an option only valid for mysqlnd and will raise an error if used with mysqli.Example on using mysqli_options to increase size of max_allowed_packet for working with big blobs.
function dbConnect()
{
$user = 'jomama';
$pass = 'cartoon';
$dbName = 'LifeCycle';
$host = 'localhost';
$mysqli = mysqli_init();
mysqli_options($mysqli,MYSQLI_READ_DEFAULT_GROUP,
"max_allowed_packet=50M");
mysqli_real_connect($mysqli,$host, $user, $pass,$dbName)
or die ('<P>Unable to connect</P>');
return $mysqli;
}
