示例

示例 #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'));
?>

以上示例会输出：

Dr. Phil

示例 #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);
?>

以上示例会输出：

array(2) {
  [0]=>
  bool(false)
  [1]=>
  int(0)
}

注释

注意:

如果函数有参数需为引用，那么它们必须以引用方式传入。
