Why is My PHP Script Showing a 500 Internal Server Error Even Though Error Display is Enabled?

Troubleshooting PHP 500 Internal Server Errors

Users facing 500 Internal Server Errors when executing PHP scripts despite prior error display may encounter a server configuration issue. To resolve this, consider the following measures:

PHP Configuration Adjustments:

Examine the "error_reporting", "display_errors", and "display_startup_errors" settings within the php.ini file. Ensure these are set as follows:

• error_reporting: E_ALL
• display_errors: On
• display_startup_errors: Off

Runtime Script Modifications:

Alternatively, you can modify these settings at runtime within the script itself to set them dynamically:

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

Server Restart:

After making these adjustments, restart the web server to apply the changes. This should allow PHP to display errors rather than an internal server error.

Additional Considerations:

• While "display_errors" can be useful for debugging purposes, it is recommended to disable it on production servers to prevent sensitive error details from being exposed publicly.
• Instead of using "display_errors", consider enabling "log_errors" to record errors to a log file for later review.
• If the issue persists, consult the Apache configuration files or debug the script further to identify any additional causes.
