PHP display errors

Add the following line of code to your top of PHP code

    ini_set('display_errors', 1);
    ini_set('display_startup_errors', 1);
    error_reporting(E_ALL);

• The function ini_set will try to override the configuration found in the PHP ini file
• The display_errors is a directive that determines whether the error will remain hidden and displayed to the user.
• display_startup_errors is a directive that is used to find errors during PHP’s startup sequence.
