How can one implement a proper error handling mechanism in PHP to prevent the code from continuing execution after displaying an error message?

To implement a proper error handling mechanism in PHP to prevent the code from continuing execution after displaying an error message, you can use the try-catch block. This allows you to catch any exceptions that occur and handle them gracefully without the code continuing to execute. Within the catch block, you can display an error message and stop further execution.

try {
    // Code that may throw an exception
    // For example, a database query that could fail
} catch (Exception $e) {
    // Display an error message
    echo "An error occurred: " . $e->getMessage();
    // Stop further execution
    exit;
}
