迅速确定php多维数组的深度的方法_PHP
例如有一个多维数组:
复制代码 代码如下:
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:
复制代码 代码如下:
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);
?>
