Login remember using cookie in PHP

A cookie, also known as a web cookie, browser cookie, and HTTP cookie, is a piece of text stored on a user’s computer by their web browser. A cookie can be used for authentication, storing site preferences, shopping cart contents, the identifier for a server-based session, or anything else that can be accomplished through storing text data.

Cookie can have up to seven parameters but mostly first three are used.

The first 3 parameters are:

1. name:  refers to cookie name e.g. cookname

2. value: refers to cookie value stored in cookie name e.g. $_COOKIE['cookname'] => ‘cookvalue’

3. expire: refers to time the cookie expires, if omitted cookie expires on browser close e.g. time()+60*60*24*1 – this time will set the cookie to expire in 1day.

Combining the parameters, cookie set command becomes:

setcookie('cookie_username','username_value', time()+60*60*24*1); 

The above set cookie can be accessed by:

echo $_COOKIE'cookie_username'];

    This is EXTREMELY INSECURE. Nobody should use this method to remember a login. Every major browser provides you the ability to manually edit cookies, and an attacked would have a very easy time forcing their way into your site if you use this method.

    This is bad, amateur advice, and very irresponsible.

    actually that’s why I told you about adsense…
