	How to use cookies in PHP, Saturday, May 17, 2008

	Cookies in PHP is done by using the statement setcookie() , this statement is available from the time when version 3 of PHP. int setcookie (string Name [, string Value [, int Expire [, string Path [, string Domain [, int Secure]]]]]); setcookie() defines a cookie that is sent the information from the header. Cookies are sent before any html tag; therefore, we call one of these statements before any tag <html> or <head>. This is a restriction of cookies, not for PHP. All messages, except the name are optional. Name . Name of the cookie. If we create a cookie only with its name, the cookie name is existing in the Client under said name will be deleted. We can also replace to any argument with an empty string(""). Value . Value to be stored by the cookie in the Client. Expire . The argument expire is an integer argument that indicates the time of the cookie will be deleted in the time format returned by the UNIX statements time() and mktime(). Time() + N seconds of duration is commonly used to specify the duration of the cookie. Path . Subdirectory where the cookie has a value. Domain . Domain where the cookie has a value. If we establish www.yourdomain.com as domain, the cookie is not set for domain.com. Meanwhile, if we establish yourdomain.com as domain, the cookie is set as for yourdomain.com as for www. yourdomain.com. Secure . The secure indicates that the cookie will only be set by a secure HTTPS connection. Example setcookie("Ron", "Victor", time()+3600,"/","yahoo.com"); In this example, we set a user name cookie that has the value Victor , lasts 1 hour (3600 seconds) valid for the whole domain yahoo.com Earthlink Netscape Netvouz RawSugar Shadows Sphinn StumbleUpon Yahoo MyWeb
