PHP : Function Reference : PostScript document creation : ps_get_value

ps_get_value

Gets certain values (PECL ps:1.1.0-1.3.5)
float ps_get_value ( resource psdoc, string name [, float modifier] )


Code Examples / Notes » ps_get_value

tilman dot schroeder

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 ...
PHP version 4.4.4-8, pslib verision 0.2.7-1 (Debian etch)
Bye and a happy new year!
