Looping through an unset statement

[slanton]

I want to loop through an unset statement but can't seem to get the syntax right eg
[code]
for($i=0;$i<14;$i++){
unset($_SESSION['test$i']);
}
[/code]
doesn't work. Is this possible?

[hackerkts]

It's working for me..

[slanton]

Really?
I wonder what the ...I am doing wrong
[code]
<?php
$_SESSION['test1']="test1";
$_SESSION['test2']="test2";

for($i=0;$i<14;$i++){
unset($_SESSION['test$i']);
}

echo $_SESSION['test1'];
echo $_SESSION['test2'];

?>
[/code]

[hackerkts]

Hmm.. Let me try..

[b]Edit[/b]:
OMG >.< Now then I know it's not working in loop, or you wanna use a long way ?
[code]$_SESSION['test1'] = "";
$_SESSION['test2'] = "";[/code]

Your code will not work as PHP is unsetting a session var called 'test$i' it is treating your variable as-is meaning it is not swaping $i with its value.

So change your unset code to this:
[code]unset($_SESSION['test' . $i]);[/code]
Now PHP will parse the variable $i rather than treating it as text.

Also if you want to destroy a session you should use session_destroy();

Thanks..that works.
Doesn't session_destroy kill all session data ..I just want to unset a particular variable.

Yeah session_destory kills the whole session. You'll want to use unset to kill seperate session vars within a session.
