通過php中的多維數組進行迭代

Question

我有多維數組如何遍歷每個元素，對於簡單的數組，我們可以像這樣

 $numbers = array( 1, 2, 3, 4, 5);
foreach( $numbers as $value )
{
  echo "Value is $value <br />";
}

那么如何遍歷以下數組

array(852,array(456,1234,784),array(102,896,121),array(1222,963,123),array(102,896,121),1234,array(102,896,121),676,54654,array(123,4785,123),array(41256,789),741,123,array(4561))

Answer 1

嘗試這種方式

$array=array(852,array(456,1234,784),array(102,896,121),array(1222,963,123),array(102,896,121),1234,array(102,896,121),676,54654,array(123,4785,123),array(41256,789),741,123,array(4561));
    foreach( $array as $value )
    {
     if(is_array($value))
     {
         foreach($value as $v)
         {
             echo "Value is $v <br />";
         }
     }
     else
     {
         echo "Value is $value <br />";
     }
    }

Answer 2

嘗試這個。

$arr = array(852, array(456, 1234, 784), array(102, 896, 121), array(1222, 963, 123), array(102, 896, 121), 1234, array(102, 896, 121), 676, 54654, array(123, 4785, 123), array(41256, 789), 741, 123, array(4561));

foreach ($arr as $val)
{
    if (is_array($val))
    {
        foreach ($val as $valIn){
            echo $valIn."<br>";
        }
    } else
    {
        echo $val."<br>";
    }
}
