iSelfSchooling - How to read from cookies in PHP?

You read cookies’ value the same as you have been reading POST store method. The following is the format: $_COOKIE[‘name’]; Remember that the cookies’values are accessible to all scripts in your application except the one that sent it.

setcookie (‘name’, ‘Borna and Dana’);
print $_COOKIE[‘name’];

The value on print will be null.

Now, let us write a PHP to view all user’s information. Type the following code into notepad and save it as “view_cookies.php” then upload it to your web server.

<body>

<?php
// always have your error handling turn on.
ini_set (‘display_errors’,1);
error_reporting (E_ALL & ~E_NOTICE);

// check for user information
if (isset ($_COOKIE[‘name’])) {
print “Name: {$_COOKIE[‘name’]};\n”
}
if (isset ($_COOKIE[‘ssn’])) {
print “Social Security Number: {$_COOKIE[‘ssn’]};\n”
}
if (isset ($_COOKIE[‘phone’])) {
