Are there any limitations to handling errors in PHP, particularly with fatal errors?

Handling fatal errors in PHP can be challenging as they halt the execution of the script, making it difficult to recover from. One way to mitigate this issue is by using a combination of error handling techniques such as try-catch blocks and error logging to catch and log fatal errors. Additionally, using functions like set_error_handler() can help customize error handling for different types of errors. 

// Set a custom error handler to catch and log fatal errors
function customErrorHandler($errno, $errstr, $errfile, $errline) {
    error_log("Fatal error: $errstr in $errfile on line $errline");
    // Additional error handling logic can be added here
}

set_error_handler("customErrorHandler");

// Trigger a fatal error to test the custom error handler
undefinedFunction(); // This function does not exist and will trigger a fatal error
