PHP mysqli ssl_set() Function
Example - Object Oriented style
Create an SSL connection:
<?php
$mysqli = mysqli_init();
if (!$mysqli) {
die("mysqli_init failed");
}
$mysqli -> ssl_set("key.pem", "cert.pem", "cacert.pem", NULL, NULL);
if (!$mysqli -> real_connect("localhost","my_user","my_password","my_db"))
{
die("Connect Error: " . mysqli_connect_error());
}
// Some queries...
$mysqli -> close();
?>
Look at example of procedural style at the bottom.
Definition and Usage
The ssl_set() / mysqli_ssl_set() function is used to establish secure connections using SSL. However, this function does nothing unless OpenSSL support is enabled.
Note: This function must be called before real_connect().
Note: MySQL Native Driver does not support SSL before PHP 5.3.3. MySQL Native Driver is enabled by default on Microsoft Windows from PHP 5.3+.
