Remove Sessions

To remove or delete session we use two function destroy and unset first use unset to remove all sessions and then destroy example:

<!DOCTYPE html>

<html>

<body>

<?php

session_start();

$_SESSION['mysession1']='php-guides1';

$_SESSION['mysession2']='php-guides2';

$_SESSION['mysession3']='php-guides3';

$_SESSION['mysession4']='php-guides4';

$_SESSION['mysession5']='php-guides5';

Session Values=<?php

//Remove Or delete Sessions

session_unset();

session_destroy();

echo "<pre style='color:red'>";

print_r($_SESSION);

echo "</pre>";

</body>

</html>

//print output

Session Values=

Array
(
)

Multiple Session Values

We can set multiple session at one time and easily fetch them in php Example:

<?php

<!DOCTYPE html>

<html>

<body>

<?php

session_start();

$_SESSION['mysession1']='php-guides1';

$_SESSION['mysession2']='php-guides2';

$_SESSION['mysession3']='php-guides3';

$_SESSION['mysession4']='php-guides4';

$_SESSION['mysession5']='php-guides5';

Session Values=<?php

echo "<pre style='color:red'>";

print_r($_SESSION);

echo "</pre>";?>

</body>

</html>

?>

Output Print:

Session

Session stored values in variables, and from this variables we can fetch data on multiple pages .
to create session we should start it first example :

<!DOCTYPE html>

<html>

<body>

<?php

//its start session

session_start();

//set variable for session

$_SESSION['mysession']='php-guides';

Session Value=<?php print($_SESSION['mysession']);?>

</body>

</html>
