php如何遍历一个复杂的多维数组
比如有这样一个数组,毫无规律,怎么遍历?

PHP code

你遍历后想做什么? 可以用递归处理
PHP code
// 作为回调函数。 参数将不会是数组function doSomething($value) {     echo $value;}function look(array $array){     foreach($array as $value)     {         // 如果仍为数组,则继续遍历         if(is_array($value))             look($value);         else             call_user_func('doSomething', $value);     }}<div class="clear">
                 
              
              
        
            </div>
