How to Obtain Informative Error Messages in PHP
When executing PHP scripts, it's frustrating to encounter blank screens with no indication of errors. Simple syntax errors, failed function calls, and other issues can lead to such cryptic results.
PHP, unlike Java, does not produce helpful error messages by default. To rectify this, three options are available:
1. Error Logging
Enable error logging by setting log_errors to On in the PHP configuration. This will capture all errors in a log file, which can be viewed to identify and troubleshoot the issue.
2. Displaying Errors in Real-Time
To display errors as they occur, add the following lines to your script:
error_reporting(E_ALL); ini_set('display_errors', 'On');
Remember to set display_errors to Off in a live server environment to prevent user exposure. For syntax errors, these commands must be enabled in the php.ini file.
3. Error Checker Editors
Utilize an editor that integrates error checking while you type, such as PhpEd, VSCode, or PHPStorm. These editors provide robust debuggers with detailed information and a user-friendly experience.
