Note that the modifier parameter is REQUIRED in some (perhaps all) cases where you would not believe it to be required but optional:
<?php
$texty=ps_get_value($ps,'texty'); // does NOT work!
// but this works, however:
$foo=NULL;
$texty=ps_get_value($ps,'texty',$foo); // DOES work!
// this works too:
$texty=ps_get_value($ps,'texty',NULL);
?>
if your script just fails and sends a file with zero length to your browser just try the workaround above. saves time and you will not get upset ;)
would be nice if somebody would be able to tell why pslib behaves this way ...
