Code sharing that tests whether php connects to mysql successfully

The method is simple:

Save the following code as test.php and put it in the web directory to execute it.

<?php 
/**
*  test php with mysql The connection 
*  Editor: www.ofstack.com
*/
$link=mysql_connect("localhost","root","123"); 
if(!$link) echo "FAILD! Wrong connection, wrong username and password "; 
else echo "OK! Can be connected "; 
?>

The parameters of the mysql_connect() function are, in turn, mysql server name or IP, mysql user name and mysql user password.
