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); ?>
Copy after login
