What is the purpose of the exit() function in PHP

The exit() function in PHP is used to terminate the current script and optionally send a message or status code to the calling program. This function is especially useful when you want to stop execution of a script after a certain condition is met or if an error occurs.

Example of the exit() function


        <?php
        // Example of exit() function in PHP
        $condition = true;

        if ($condition) {
            echo "Exiting the script.";
            exit(); // Terminate the script
        }

        echo "This line will not be executed.";
        ?>
