I'm correcting a 'few' php-files for a friend, but I got this line of code:
CODE
$ban = ($data->login) ? $lban : $iban;

and I don't know what it does xD

Could someone please explain me what this line does?

Thanks

That is a terniary (sp) statement. Like an IF statement, but very concise.
If the condition [$ban = ($data->login)] is evaluated to true, then perform the assignment following the '?'. [$lban]
If the condition [$ban = ($data->login)] is evaluated to false, then perform the assignment following the ':'. [$iban]

It's the same code as this:

CODE
if ($data->login) {
    $ban = $lban;
}
else {
    $ban = $iban;
}

Excellent... thanks jhaslip. I had bumped into terniary operators on a php tutorial before but the tutorial explained them and I didnt quite get them. I didnt understand. And a search in google didnt help me much either.
