PHP offers a comprehensive system for reporting errors, allowing developers to gain insight into what's going wrong within their code.How to Handle All PHP Errors The error_reporting() function sets the error_reporting directive at runtime, controlling which types of errors are displayed or logged.A Guide To PHP Error Messages For Designers For active development and debugging, it's highly recommended to set this to `E_ALL` to capture every possible issue. This includes:
* Parse errors: These are syntax errors that prevent PHP from parsing your code. They are often the easiest to find and fix as PHP will typically point you directly to the line causing the problem.
* Fatal errors: These are critical errors that halt script execution, such as calling an undefined function or out-of-memory conditions.
* Warnings: These indicate potential problems that don't necessarily stop the script but might lead to unexpected behavior, like using an uninitialized variable.
* Notices: These are similar to warnings but are generally less severe, alerting you to minor issues like using a variable before it has been assigned a value.Troubleshoot PHP errors - Documentation

One of the primary methods to check the error log file is by consulting PHP's dedicated error log.PHP Error Handling Unless logging has been explicitly disabled, this file will contain a record of all errors encountered. The exact location of this log file can be configured in `php.ini`. For developers working with platforms like WordPress, checking the error logs can be done through tools like the WordPress debugging system or via FTP to access the server's log files.

PHP provides several built-in functions that aid in error detection:
* `error_get_last()`: This function retrieves the last error that occurred. While useful, it's important to note that it may not capture all types of errors, such as those preceding a fatal error or errors from certain built-in functions like `mail()`.
* `die()`: For critical errors where script execution should cease immediately, the using die() method can be employed to halt the process and display a user-friendly message.
Effective PHP error reporting and PHP error handling and debugging go beyond just enabling error display. It involves a proactive approach:
* Consistent Logging: Ensure that errors are consistently logged, especially in production environmentsThe Complete Guide to PHP Error Reporting · Raygun Blog.
* Meaningful Error Messages: While PHP provides technical details, consider providing more user-friendly messages to end-users when necessary, especially if errors occur in a customer-facing application.

* Environment-Specific Handling: Adapt your error handling strategy based on the environment. Development environments should be verbose with error display, while production environments should prioritize logging and security.
