如何爆炸這個數組並顯示給調用變量？

Question

我有一個字符串，它看起來像：

$string = "12,32,23,32-23X.12,32,23,32-20X"; 

我怎樣才能把這個字符串轉換像一個數組：

Array ( 
    [0] => Array ( 
       [0] => Array ( 
          [0] => 12 
          [1] => 32 
          [2] => 23 
          [3] => 32 
         ) 
       [1] => 23X 
      ) 

    [1] => Array ( 
       [0] => Array ( 
          [0] => 11 
          [1] => 31 
          [2] => 21 
          [3] => 31 
         ) 
       [1] => 20X 
      ) 
) 

和結果將是：

12:23X 
32:23X 
23:23X 
32:23X 
11:20X 
31:20X 
21:20X 
31:20X 

Answer 1

<?php 
$string = "12,32,23,32-23X.12,32,23,32-20X"; 
$parts=explode(".",$string); 
foreach($parts as $part){ 
    $innerpart = explode("-",$part); 
    $nums = explode(",",$innerpart[0]); 
    foreach($nums as $num){ 
     echo $num.":".$innerpart[1]; 
    } 
} 
?> 

您必須在嵌套循環中使用三次explode()。
