PHP递归遍历输出任意长度多维数组算法(格式化打印数组算法)

PHP:7.4

首先，先创建一个数组;

$array = array("a"=>"60","b"=>"56","c"=> array("a"=>"60","b"=>"56",array("a"=>"60","b"=>"56","c"=>array("a"=>"60","b"=>"56","c"=>"31"))) );

这个是个多维数组

这是主要函数

function go_array($array,$i = 0,$cut_line = "----|"){//$i当前维度    foreach ($array as $key => $value){//遍历当前数组        $cut = "";//初始化分割线        for ($o = 0; $o < $i; $o++) {//计算维度             $cut .= $cut_line;//当前维度分割线        }        echo $cut."[".$key. "] => " . "[".$value."]
";//输出浏览器(输出终端 把
改成\n)        if(is_array($value)){//判断$value是否维数组            $i = $i + 1;//加1为下一维数组            go_array($value,$i);//执行一次此函数            $i = $i - 1;//减1为当前维数组        }    }}

总代码如下:

"60","b"=>"56","c"=> array("a"=>"60","b"=>"56",array("a"=>"60","b"=>"56","c"=>array("a"=>"60","b"=>"56","c"=>"31"))) );go_array($array);function go_array($array,$i = 0,$cut_line = "----|"){    foreach ($array as $key => $value){        $cut = "";        for ($o = 0; $o < $i; $o++) {             $cut .= $cut_line;        }        echo $cut."[".$key. "] => " . "[".$value."]
";        if(is_array($value)){            $i = $i + 1;            go_array($value,$i);            $i = $i - 1;        }    }}?>

浏览器输出结果 （如果要输出终端的话，请把
改成\n）

[a] => [60]
[b] => [56]
[c] => [Array]
----|[a] => [60]
----|[b] => [56]
----|[0] => [Array]
----|----|[a] => [60]
----|----|[b] => [56]
----|----|[c] => [Array]
----|----|----|[a] => [60]
----|----|----|[b] => [56]
----|----|----|[c] => [31]
