How to Display PHP Errors Using .htaccess Only?

Displaying PHP Errors Using .htaccess

In web development, accurate error display is crucial for troubleshooting issues efficiently. However, errors may not always be visible by default, especially during testing. This article demonstrates how to enable error display using only the .htaccess file, without requiring modifications to PHP configuration files.

Problem:

You are unable to display PHP errors on a website and have access to only the .htaccess file. How do you make all errors visible using this file?

Answer:

To enable PHP error display via .htaccess, follow these steps:

1. Open the .htaccess file in your preferred text editor.
2. Add the following directives:

<code class="htaccess">php_flag display_startup_errors on
php_flag display_errors on
php_flag html_errors on</code>

3. These directives turn on display of startup errors, general errors, and error messages formatted in HTML, respectively.
4. To additionally log errors to a file, add the following directive:

<code class="htaccess">php_value error_log /home/path/public_html/domain/PHP_errors.log</code>

Replace /home/path/public_html/domain/PHP_errors.log with the desired location and filename for the error log.

5. Save the changes to your .htaccess file.

Note:

If you encounter an "Internal server error" message after making these changes, it indicates that there are underlying server configuration issues that need to be addressed. Consult your web hosting provider for assistance.
