[help][php] custom 404 page not working

[Macemore]

Well I'm basically trying to set something like

$_SERVER['HTTP_USER_AGENT'];

as a variable.
but for some reason (don't ask me) it doesn't work.
This is all I'm doing:

$ua = '$_SERVER['HTTP_USER_AGENT']'; //notice the accordingly abbreviated name?

but it doesn't work, any help?

Thanks!

$ua = $_SERVER["HTTP_USER_AGENT"];
echo $ua;

Is the way it should be done although i echoed it out

As Xenous said you can just do that, but to save lines:

<?php
echo $_SERVER["REMOTE_ADDR"];
?>

Also, if you ever wanted to view all the $_SERVER[] values:

<?php
foreach ( $_SERVER as $k => $v )
{
    echo '$_SERVER[' . $k . '] = ' . $v . '<br />';
}
?>

That code can be used for almost everything, $_COOKIE, $_SESSION, $_POST, $_GET etc.
