How can you ensure that PHP code is only executed when a specific condition is met in a form submission?

To ensure that PHP code is only executed when a specific condition is met in a form submission, you can use an if statement to check the condition before executing the code. This way, the PHP code will only run if the condition evaluates to true.

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Check if the specific condition is met
    if (/* your condition here */) {
        // Execute your PHP code here
    }
}
