To set a cookie in PHP, the setcookie() function is used.The setcookie() function needs to be called prior to any output generated by the script otherwise the cookie will not be set.
setcookie(name, value, expire, path, domain, security);
Parameters: The setcookie() function requires six arguments in general which are:
Creating Cookies: Creating a cookie named Auction_Item and assigning the value Luxury Car to it.The cookie will expire after 2 days(2 days 24 hours 60 mins * 60 seconds).
<?php
setcookie("Auction_Item", "Luxury Car", time()+2*24*60*60);
?>
Note: Only the name argument in the setcookie() function is mandatory.To skip an argument,the argument can be replaced by an empty string(“”).
Checking Whether a Cookie Is Set Or Not: It is always advisable to check whether a cookie is set or not before accessing its value.Therefore to check whether a cookie is set or not, the PHP isset() function is used.
To check whether a cookie “Auction_Item” is set or not,the isset() function is executed as follows:
<?php
if(isset($_COOKIE["Auction_Item"])){
echo "Auction Item is a " . $_COOKIE["Auction_Item"];
} else{
echo "No items for auction.";
}
?>
Output:
Auction Item is a Luxury Car.
Accessing Cookie Values: For accessing a cookie value, the PHP $_COOKIE superglobal variable is used.It is an associative array that contains a record of all the cookies values sent by the browser in the current request.The records are stored as a list where cookie name is used as the key.
To access a cookie named “Auction_Item”,the following code can be executed:
<?php
echo "Auction Item is a " . $_COOKIE["Auction_Item"];
?>
Output:
Auction Item is a Luxury Car.
Deleting Cookies: The setcookie() function can be used to delete a cookie.For deleting a cookie, the setcookie() function is called by passing the cookie name and other arguments or empty strings but however this time, the expiration date is required to be set in the past.
To delete a cookie named “Auction_Item”,the following code can be executed:
<?php
setcookie("Auction_Item", "", time()-60);
?>

Setting cookies in PHP is quite straightforward. You can use the setcookie()
function to do this. Here's a basic example:
<?php
// Set a cookie named "username" with the value "JohnDoe" that expires in 1 hour
setcookie("username", "JohnDoe", time() + 3600);
?>
In this example, we're setting a cookie named "username" with the value "JohnDoe," and it will expire in 1 hour (3600 seconds). You can customize the name, weight, and expiration time according to your needs. Cookies can be accessed in subsequent PHP scripts to retrieve or modify their values.
