Why does the error “expected to be a reference, value given” appear?

Question

It fires out when I try to call function with argument by reference

function test(&$a) ...

through

call_user_func(\'tes         


        

Answer 1

I've just had the same problem, changing (in my case):

$result = call_user_func($this->_eventHandler[$handlerName][$i], $this, $event);

to

$result = call_user_func($this->_eventHandler[$handlerName][$i], &$this, &$event);

seem to work just fine in php 5.3.

It's not even a workaround I think, it's just doing what is told :-)
