boolean flag not working

[Griffyn]

Hi all,

I'm learning as I go with PHP, and I can't figure out why my boolean code isn't working:

$backflag == false;
$roomspecs = explode ( '/', $roomdetail[1] );
foreach ( $roomspecs as $roomspec ) {
  if ( strtolower ( substr ( $roomspec, 0, 1 ) ) == 'c' ) {
    $backflag == true;
    $return == 'x';
    break;
  }
}
if ( !$backflag ) {
  $return == 'y';
}

The problem is that my $return var is getting set with either 'y' or 'xy', when it should only be 'x' or 'y'. I'm clearly doing something fundamentally wrong. What is it?

argh. Ok, I'm messing up my assigns (=) and my comparisons (==). Easy to fix. Used to Delphi, where it figures out both by just using (=).

Correct, for comparisons its == or even ===. For assignments its just =.

Unknown has caused an Unknown Error on Unknown and must be shutdown to prevent damage to Unknown.

Actually, Delphi uses := for assignment and = for comparisons.
