Addition to the last note. in the array I have used array($this, "myMethod") to make it use an internal function in a class. 

I reckon this is how it is meant to work (not tested)

$myObj = new MyObj()

xslt_set_error_handler_($xh, array($myObj, "myErrorMethod"));

To set the error handler to the instance of an object, use the:



xslt_set_error_handler($xh, array($obj, $method))



syntax.
