Test connection to MySQL Database using PHP

Create a blank new file called “testmysql.php” (without the quotes) and paste the following code snippet:

 
<?php 

$myLink = mysqli_connect( 'localhost', 'my_user', 'my_password', 'my_database' ); 

if ( !$myLink ) { 

    die( 'Could not connect to MySQL: ' . print_r( mysqli_error_list( $myLink ) ) ); 

} 

echo 'Connection OK'; 

mysqli_close($myLink);


?>

NOTE: Replace placeholders “my_user”, “my_password” and “my_database” for your current values.

Now you need to navigate to the corresponding page:

http://example.com/testmysql.php

You should see a “Connection OK” message and if there’s an error, it’ll display the error number and description.
