Display All Errors in PHP

To display all errors in PHP, you can configure the error reporting settings in your PHP script or in the PHP configuration file (php.ini). Setting the error reporting level to include all errors helps you identify and debug issues during development. However, in production environments, it is recommended to hide error messages for security reasons.

Here are two methods to display all errors in PHP:

1. Display Errors in PHP Script:
   You can enable error reporting directly in your PHP script using the error_reporting() and ini_set() functions. Place the following code at the beginning of your PHP script:

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

• error_reporting(E_ALL): Sets the error reporting level to include all types of errors, warnings, and notices.
• ini_set('display_errors', 1): Enables the display of error messages on the screen.

Remember that setting display_errors to 1 is suitable for development and debugging purposes. In production, it is recommended to set display_errors to 0 or remove the ini_set('display_errors', 1) line to hide error messages from the users.

2. Display Errors in php.ini:
   You can also modify the PHP configuration file (php.ini) to display all errors globally. Locate the php.ini file and look for the following lines:

display_errors = Off

Change display_errors to On:

display_errors = On

Make sure to restart your web server (e.g., Apache or Nginx) after making changes to the php.ini file for the modifications to take effect.

By setting display_errors to On in the php.ini file, all errors will be displayed on the screen for all PHP scripts on the server.

Caution: Displaying error messages to users in a production environment is not recommended, as it can expose sensitive information about your server and application. In a production environment, error messages should be logged and handled gracefully to avoid security risks. Consider using custom error handling, logging, and displaying user-friendly error messages for your production application.
