Returns an array of the used variables in the Closure.
此函數沒(méi)有參數。
Returns an array of the used variables in the Closure.
示例 #1 ReflectionFunctionAbstract::getClosureUsedVariables() example
<?php
$one = 1;
$two = 2;
$function = function() use ($one, $two) {
static $three = 3;
};
$reflector = new ReflectionFunction($function);
var_dump($reflector->getClosureUsedVariables());
?>
以上例程的輸出類(lèi)似于：
array(2) {
["one"]=>
int(1)
["two"]=>
int(2)
}
