Consider the following command line script:

#!/usr/local/bin/php -q
<?php

exit( 0 );

?>

With PHP 4.1.2, this returned 0 to the calling
process (e.g. the $? shell variable).  With
PHP 4.2.1, this no longer works - exit(0) returns
255.

I don't know if this is intentional or not, but
now the only way I can use 0 for success and !0
for errors is:

$return_val = whatever();

if ( $return_val === 0 )
  return 0;
else
  exit( $return_val );

Can this be returned to the older way of doing
things?
