What are common pitfalls when using error handlers in PHP projects?

One common pitfall when using error handlers in PHP projects is not properly handling all types of errors, which can lead to unexpected behavior or uncaught exceptions. To solve this, make sure to define error handling for all possible error types, including fatal errors, warnings, and notices. 

// Define a custom error handler function
function customErrorHandler($errno, $errstr, $errfile, $errline) {
    // Handle errors based on error type
    switch ($errno) {
        case E_USER_ERROR:
            // Handle user errors
            break;
        case E_USER_WARNING:
            // Handle user warnings
            break;
        case E_USER_NOTICE:
            // Handle user notices
            break;
        default:
            // Handle other types of errors
            break;
    }
}

// Set custom error handler
set_error_handler("customErrorHandler");
