Understanding PHP Errors
Before we dive into how to check PHP errors in Drupal, it is essential to understand what PHP errors are and their implications on your website. PHP errors occur when there is a problem with your code, and the server is unable to execute it. These errors can range from syntax errors, and undefined variables, to memory issues and can cause your website to malfunction or even crash.
Checking for PHP Errors in Drupal
There are several ways to check for PHP errors in Drupal, but we will focus on two methods:
Method 1: Enabling Error Reporting
Enabling error reporting in Drupal is a simple and effective way of checking for PHP errors. Follow the steps below:
- Log in to your Drupal website’s backend.
- Navigate to the “Reports” tab.
- Click on “Recent log messages.”
- Under “Type,” select “PHP.”
- Check if there are any error messages displayed.
If there are no error messages, then your website is functioning correctly. However, if there are error messages, then you will need to address the issues causing them.
Method 2: Enabling PHP Error Logging
Enabling PHP error logging is another effective way of checking for PHP errors in Drupal. Follow the steps below:
- Access your Drupal website’s root directory.
- Locate the “php.ini” file and open it.
- Search for “error_log” and uncomment it by removing the semicolon (;).
- Specify the file path where the error log should be saved.
- Save the changes and exit.
Once you have enabled PHP error logging, you can check for error logs in the specified file path. This method is especially useful when you need to debug your website continuously.
