The above example will output:
Dr. Phil
Example #2 ReflectionFunction::invokeArgs() with references example
<?php function get_false_conditions(array $conditions, array &$false_conditions) { foreach ($conditions as $condition) { if (!$condition) { $false_conditions[] = $condition; } } } $function_ref = new ReflectionFunction('get_false_conditions'); $conditions = array(true, false, -1, 0, 1); $false_conditions = array(); $function_ref->invokeArgs(array($conditions, &$false_conditions)); var_dump($false_conditions); ?>
The above example will output:
array(2) { [0]=> bool(false) [1]=> int(0) }
Notes
Note:
If the function has arguments that need to be references, then they must be references in the passed argument list.
