How to Start a PHP Session?

You can start a session in PHP by using the session_start() function. This function will, by default, first check for an existing session. If a session already exists, it will do nothing, but it will create one if there’s no pre-existing session available

<?php

session_start();

if( isset( $_SESSION['counter'] ) ) {

$_SESSION['counter'] += 1;

}else {

$_SESSION['counter'] = 1;

}

$count= "This page is visited ". $_SESSION['counter'];

$count.= " time during this session.";

<html>

<head>

<title>Starting a PHP session</title>

</head>

<body>

<?php echo ( $count); ?>

</body>

</html>

How to Destroy a Session in PHP?

Example: Using unset() to Destroy a Session Variable

<?php

unset($_SESSION[‘counter’]);
