How should error messages be accurately quoted and addressed in PHP code debugging?

When debugging PHP code, error messages should be accurately quoted and addressed to identify the root cause of the issue. One common practice is to display the error message using the `echo` or `var_dump` function to see the exact error being thrown by PHP. This helps in pinpointing the specific line of code or variable causing the error.

// Example of displaying an error message
try {
    // Your PHP code that might throw an error
} catch (Exception $e) {
    echo 'Error message: ' . $e->getMessage();
}
