PHP中保留key值把value置0，嵌套数组可用

实现一个把PHP数组中所有元素设置为0的函数，用了递归

public  function setArraytoZero(&$array) {        foreach ($array as &$value){            if(is_array($value)) {                $this->setArraytoZero($value);            }            else {                $value = 0;            }        }    }
Copy after login
