Why Does PHP Hide Error Messages, and How Can I Make It Show Them?

Fixing PHP's Silence on Error Messages

PHP's default behavior of suppressing error messages can be frustrating during development and debugging. Understanding the reasons behind this and learning how to configure PHP to display errors is crucial.

Root Cause:

PHP's display_errors directive controls whether error messages are displayed. By default, it's set to Off, suppressing errors in a production environment for stability and security reasons.

Configuration Options:

For Individual Scripts:

To enable error display for a specific script, add the following lines at the beginning:

ini_set('display_errors', 1);
error_reporting(~0);

For Development Environments:

If the website is a development or testing site, you can modify the php.ini configuration file:

1. Locate the error_reporting and display_errors settings.
2. Set error_reporting to E_ALL (or ~0) to report all errors and warnings.
3. Set display_errors to On to enable error display.

Example:

error_reporting = E_ALL
display_errors = On

Note: Always remember to revert these changes to their default values in production environments to ensure stability.
