How can error handling be improved in PHP to provide more meaningful error messages?

Error handling in PHP can be improved by using custom error handling functions to provide more meaningful error messages. By creating custom error handlers, developers can catch specific errors, log them, and display user-friendly error messages. This allows for better debugging and troubleshooting of issues within the application. 

// Define custom error handler function
function customErrorHandler($errno, $errstr, $errfile, $errline) {
    // Log error message to a file or database
    $errorMessage = "Error: [$errno] $errstr in $errfile on line $errline";
    error_log($errorMessage);
    
    // Display user-friendly error message
    echo "An error has occurred. Please try again later.";
}

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