Collation in MySQL Database is a set of rules used in comparisons. Because many people use MySQL with data to be stored in languages other than English, they need to select the rules of comparisons which in turn depends on the character set used for storing that data. In MySQL, data is stored using a specific character set , which can be defind at different levels; i.e., the sever, the database, the table, and the column levels. Each character set has a default collation; for instance, the Latine1 character set uses the latin1_swedish_ci collation which is the Swedish c ase i nsensitive order. Usually, when someone develops an application that involves localization (using the local language; e.g., Arabic) or Internationalization (i.e., using multiple languages), they resort to Unicode (utf-8) which has several collations. In general, it is a good idea to set the character set to utf-8 and select the relevant collation or just accept the default utf8-general-ci.

If you set the variable to " cookies ", then your users  will not have to log in each time they enter your community. The cookie will stay in place within the user’s browser until it is deleted by the user. But Sessions are popularly used, as the there is a chance of your cookies getting blocked if the user browser security setting is set high. If you set the variable to "sessions", then user activity will be tracked using browser sessions, and your users will have to log in each time they re-open their browser. Additionally, if you are using the "sessions" variable, you need to secure the " sessions " directory, either by placing it above the web root or by requesting that your web host make it a non-browsable directory. The Key difference would be cookies are stored in your hard disk whereas a session aren't stored in your hard disk. Sessions are basically like tokens, which are generated at authentication.

Before you can store user information in your PHP session, you must first start up the session. Note : The session_start() function must appear BEFORE the <html> tag. <?php session_start(); // store session data $_SESSION['views']=1; ?> <html> <body> <?php //retrieve session data echo "Pageviews=". $_SESSION['views']; ?> </body> </html>  Destroying a Session <?php unset($_SESSION['views']); ?>    You can also completely destroy the session by calling the session_destroy() function:     <?php session_destroy(); ?> 

first of all what is the need of cookie ? Why we use cookie ? Lets discuss it. With the use of POST and GET method we can fetch the data which is transfer from previous page , but suppose we want that data in all pages of my site mean throughout the site then ? Then the solution is Cookie. When you create a cookie, using the function setcookie, you must specify three arguments. These arguments are setcookie (name, value, expiration):   name : The name of your cookie. You will use this name to later retrieve your cookie, so don't forget it!   value : The value that is stored in your cookie. Common values are username(string) and last visit(date).   expiration :   The date when the cookie will expire and be deleted. If you do not set this expiration date, then it will be treated as a session cookie and be removed when the browser is restarted. Setcookie <?php    //Calculate 60 days in the future //seconds * minutes * hours * days + current time  $inTwoMonths = 60 * 60
