How to display errors in PHP

To display errors in PHP, you can adjust the error reporting settings in your PHP configuration file or in your PHP script using the error_reporting() and ini_set() functions. Additionally, you can control how errors are displayed by setting the display_errors directive.

Here are some common methods to display errors in PHP:

  1. Displaying errors in the PHP configuration file (php.ini): Open your PHP configuration file (php.ini) and find the error_reporting directive. Set it to the appropriate value to control which types of errors you want to display. For example, to display all types of errors, you can use:
error_reporting = E_ALL

Additionally, you can set the display_errors directive to On to ensure that errors are displayed:

display_errors = On

Save the changes and restart your web server for the modifications to take effect.

  1. Displaying errors in the PHP script using error_reporting(): If you don’t have access to the PHP configuration file, you can use the error_reporting() function within your PHP script to set the error reporting level. Place the function at the beginning of your script to enable error reporting:
error_reporting(E_ALL);

You can also combine different error reporting levels using the bitwise OR operator. For example, to display all types of errors except for notices, you can use:

error_reporting(E_ALL & ~E_NOTICE);
  1. Displaying errors in the PHP script using ini_set(): Alternatively, you can use the ini_set() function to modify the error reporting settings within your PHP script:
ini_set('error_reporting', E_ALL);
ini_set('display_errors', '1');

By setting display_errors to '1', errors will be displayed.

Remember to handle errors appropriately in your production environment. It’s recommended to display errors during development and testing but suppress them in production for security and user experience reasons.
