Homephp教程php手册该怎样迅速确定php多维数组的深度?

例如有一个多维数组:


array(
        array(
            array(1,3,4),
            array(
                array(
                    1,2,3
                )
            )
        ),
        array(
            array(1,2),
            array(1)
        )
    )


这个数组的深度就是5,那么如何快速的确定一个数组深度。


(PS:T不错的PHP Q扣峮:276167802,验证:csl)


其实,只是上面的答案应该再进行排序就可以了。下面清源分享一个简单的计算深度函数:


<?php
function array_depth($array) {
        $max_depth = 1;


        foreach ($array as $value) {
            if (is_array($value)) {
                $depth = array_depth($value) + 1;
  

                if ($depth > $max_depth) {
                    $max_depth = $depth;
                }
            }
        }        
        return $max_depth;
 }

$array = array( array("11"), array(),array( array(array("5", "6"), "7", "8")),array( array(array("5", "6"), "7", "8")), "9", "10");
echo array_depth($array);
?>
