Examples
Example #1 ReflectionFunction::invokeArgs() example
<?php
function title($title, $name)
{
return sprintf("%s. %s\r\n", $title, $name);
}
$function = new ReflectionFunction('title');
echo $function->invokeArgs(array('Dr', 'Phil'));
?>
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.
