Hey guys,

I have a script trying to connect to a localhost database on mysql/mariadb but it gives me the error that cannot file mysql.sock message via web, when I run it via console it runs just fine, when I do a fsockopen("/tmp/mysql.sock", 3306); it opens it, but for some reason mysqli_connect cannot open that file to connect to MySQL, please check why PHP is doing this.

NOTE: it does work when run via console, just not the web, my firewall and selinux are both disabled.

Test script:
---------------
<?php
$link = mysqli_connect("localhost", "root", "password", "mysql");

if (!$link) {
    echo "Error: Unable to connect to MySQL." . PHP_EOL;
    echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
    echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
    exit;
}

echo "Success: A proper connection to MySQL was made! The mysql database is gre$
echo "Host information: " . mysqli_get_host_info($link) . PHP_EOL;

mysqli_close($link);
?>


Expected result:
----------------
Show Success message.

Actual result:
--------------
Warning: mysqli_connect(): (HY000/2002): No such file or directory in /var/www/html/tests/mysql.php on line 3
Error: Unable to connect to MySQL. Debugging errno: 2002 Debugging error: No such file or directory
