PHP supper Global variable vedio tutorial($_COOKIE)-part-1

PHP supper Global variable vedio tutorial($_COOKIE)-part-1

<!--Now,I will teach you  $_COOKIE
Supper_GLOBAL_Variable

$GLOBALS
$_SERVER
$_REQUEST
$_POST
$_GET
$_FILES
$_ENV
$_COOKIE
$_SESSION
 -->



1.Q.    What is $_COOKIE ?


A Cookie is often used to identify a user . With PHP you can create and store this user data into cookies by using the $_COOKIE Superglobal variable. In this example we will go over how to setup a cookie (using setcookie(name, value, expire, path, domain);) and request the data later with $_COOKIE.

A cookie is created with the setcookie() function.

Syntax :

setcookie(name, value, expire, path, domain, secure, httponly);


Note: The setcookie() function must appear Before the <html> tag.


Example #1:

<?php

setcookie("user",date("m-d-y"),time()+86400*30 );

echo $_COOKIE['user'];

?>

Output : 
             5-26-2016



Example #2:

<?php

setcookie("user","salraj",time()+60*60*24*30 );

echo $_COOKIE['user'];

?>

Output : 
         salraj



Note:

time() + 60(second) * 60(minute) * 24(hour) *30(day)
                                      or
time() + 50 (day)
                                       or

time() + 86400*30 

I mean that 86400 = 1 Day So, 86400 *30  = 30 Day  


I will see real project . I use $_COOKI  . So our need two page .

setcookie.php


<?php
setcookie("user","salraj",time()+60*60*24*30);

?>

<html>
<head></head>
<body>
<h3>Sending a Cookie</h3>
<form action = "cooike.php" method = "post">
<input type = "submit" name = "submit" value = "sent cookie">
<form>

</body>
</html>



cookie.php

l>
<head>
</head>
<body>

<?php

if($_COOKIE['user1']){
echo "You user name is ".$_COOKIE['user'];;
}
else{
echo "You haven't user name !";
}

?>


</body>
</html>

A session is started with the session_start() function.
Session variables are set with the PHP global variable: $_SESSION.

For Example :

<?php
session_start();
echo $_SESSION['name'] = "Salraj";
