What are Cookies?

Cookies are often used to identify users. Cookies are small files that a server leaves on a user's computer. Whenever the same computer requests a page through the browser, it also sends the cookie. With PHP, you can create and retrieve cookie values. (Recommended learning: PHP programming from entry to proficiency)

How to create a cookie?

The setcookie() function is used to set cookies.

Note: The setcookie() function must be located before the tag.

Syntax

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

Example

In the following example, we will create a file named "user" cookie and assign it the value "Alex Porter". We also stipulate that this cookie expires after one hour:

<?php 
setcookie("user", "Alex Porter", time()+3600);
?>

<html>
<body>

</body>
</html>

Note: When sending a cookie, the cookie value will automatically be URL-encoded and automatically decoded when retrieved (for To prevent URL encoding, use setrawcookie() instead).
