Example: <?php $myStringVariant = new VARIANT("over-write me", VT_BSTR); /* works */ $result = $comobj->DoSomethingTo($myStringVariant ); /* works only with allow_call_time_pass_reference option set to "On" and may not work in a future release of PHP */ $result = $comobj->DoSomethingTo(&$myStringVariant ); /* The value in the variant can be retrieved by: */ $theActualValue = $myStringVariant->value; ?> --was-- Passing parameters by reference in PHP 4.3.2 (and in a future releases of PHP ) In PHP 4.3.2 allow_call_time_pass_reference option is set to "Off" by default and future versions may not support this option any longer.
