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).
