A cookie is often used to identify a user. A cookie is a small file that the server embeds on the user's computer. Each time the same computer requests a page with a browser, it will send the cookie too. With PHP, you can both create and retrieve cookie values. Create Cookies With PHP A cookie is created with the setcookie() function. Syntax setcookie(name, value, expire, path, domain, secure, httponly); Only the name parameter is required. All other parameters are optional. PHP Create/Retrieve a Cookie The following example creates a cookie named "user" with the value "John Doe". The cookie will expire after 30 days (86400 * 30). The "/" means that the cookie is available in entire website (otherwise, select the directory you prefer). We then retrieve the value of the cookie "user" (using the global variable $_COOKIE). We also use the isset() function to find out if the cookie is set: ExampleGet your own PHP Server Cookie named 'user' is not set!
