some help please

[Anon]

OK I am trying to run a mathematical operation on a user inputed number. The source seems valid to me but I keep coming up with strange errors. Any help would be appreciated.

<? php

function BackdoorPW ( $key )
{

$x = (( $key * -1.2456 ) + 1) * 65533;
$x = ( $x / 2 + 7) * 3;
$x /= 2 ;
return ( $x * $x );

}
?>

<?php

function BackdoorPW ( $key )
{

$x = (( $key * -1.2456 ) + 1) * 65533;
$x = ( $x / 2 + 7) * 3;

try this:

<?php

function BackdoorPW ( $key )
{

$x = (( $key -1.2456 ) + 1) 65533;
$x = ( $x / 2 + 7) 3;
$x = $x / 2 ;
return ( $x $x );

}

$x = BackdoorPW(4);

echo ( $x )
?>

you have to call the function some where in there to make it work.
