What is a preprocessor in PHP?
As it is, PHP does not have a preprocessor; it is a preprocessor that processes form variables and other environmental variables and prints HTML or general text.
How can you declare the variable in PHP?
Variables in PHP do not need to be declared like some languages (e.g. JavaScript). This is all that needs to be done to assign a variable: $variable = "Value";
How do you reset session variables?
<?php // start session session_start(); // Assign value to session $user = $_SESSION['variable_name']; // variable_name = value to store in session // To reset session variable use below method unset($user); // If you want to destroy all session variables use below method session_destroy(); // destroys all session variables ?>
How do you maintain a session in a PHP quiz script?
All you have to do to maintain a session is start it before you call any variables. Once you've started the session, you can store variables for use in later scripts. Beware though, once the user closes the browser, the sessions' over. I'd use the following SCRIPT 1: <?php // Start session session_start(); // Set some variables (this simulates form input) $_SESSION['answers']['Q1'] = 18; $_SESSION['answers']['Q2'] = 36; $_SESSION['answers']['Q4'] = "Fred"; ?> ============================= Hope that helps...
