# PHP mysqli_ssl_set() Function

PHP MySQLi Reference

## Example

Create an SSL connection:

<?php
$con=mysqli_init();
if (!$con)
{
die("mysqli_init failed");
}
mysqli_ssl_set($con,"key.pem","cert.pem","cacert.pem",NULL,NULL);
if (!mysqli_real_connect($con,"localhost","my_user","my_password","my_db"))
{
die("Connect Error: " . mysqli_connect_error());
}
// Some queries...
mysqli_close($con);
?>

## Definition and Usage

The 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 mysqli_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+.

## Syntax

mysqli_ssl_set(connection,key,cert,ca,capath,cipher);
