如何使用的foreach三维数组在PHP

Question

我有一个三维阵列，需要用它做什么，能够使用简单的解决问题 每个这样的：

for($n=0;$n<count($d["T"]);$n++) 
{ 
$d["T"][$n]["Pay"]=number_format($d["T"][$n]["Pay"], 2, '.', ''); 
} 

Answer 1

foreach ($d["T"] as &$var) { 
    $var['Pay'] = number_format($var['Pay'], 2, '.', ''); 
} 

Answer 2

最简单技术是嵌套的Foreach look ...就像

foreach($arrD as $key => $arrInternal){ 

    foreach($arrInternal as $keyIn => $Data){ 

      //Perform your operation here 
    } 

}
