Question

this is the function:

public function func(&$parameters = array())
{
}

now I need to do this:

$x->func (get_defined_vars());

but that fails. Another way:

$x->func (&get_defined_vars());

it drops an error: Can’t use function return value in write context in …

Then how to do it?

Answer 1

get_defined_vars() returns an array, not a variable. As you can only pass variables by reference you need to write:

$definedVars = get_defined_vars();
func($definedVars);

Though I don’t really see a reason to pass the array by reference here. (If you are doing this for performance, don’t do it, as it won’t help.)
