How Do I Troubleshoot 500 Internal Server Errors in PHP?

Troubleshooting 500 Internal Server Errors with PHP

When executing PHP scripts, users may encounter a 500 Internal Server Error instead of receiving detailed error messages. This can be frustrating and hinder troubleshooting efforts.

One potential cause of this behavior is incorrect configuration of PHP settings in the php.ini file. To resolve this, users should verify the values for error_reporting, display_errors, and display_startup_errors. These settings should be set to E_ALL and "On" respectively. Alternatively, these settings can be modified at the beginning of the PHP script to configure them at runtime, as shown below:

error_reporting(E_ALL);
ini_set('display_errors', 'On');

After modifying the settings, users should restart the server to ensure the changes take effect. Additionally, it's worth noting that display_errors should be disabled on production servers for security reasons. In such cases, users can enable log_errors instead to capture error messages without displaying them to end-users.
