數據添加到多維PHP數組

Question

我有輸出以下的數組：

Array 
(
    [0] => Array 
     (
      [0] => wordpress 
     ) 

    [1] => Array 
     (
      [0] => wordpress 
      [1] => forms 
     ) 

    [2] => Array 
     (
      [0] => wordpress 
      [1] => galleries 
     ) 

    [3] => Array 
     (
      [0] => wordpress 
      [1] => ecommerce 
     ) 

    [4] => Array 
     (
      [0] => wordpress 
      [1] => ecommerce 
      [2] => wp-e-commerce 
     ) 
) 

我怎麼會去加入一個項目到[0] => Array？

這是我建立了我的陣列方式：

$cats = array(); 
foreach($items as $x=> $item) { 

     $ex = explode("/",$item['path']); 
     $cats[] = explode("/",$item['path']); 

     echo $item['name'].' - '. $item['path']; 
     echo "<br>"; 
    } 

print_r($cats); 

任何幫助將不勝感激！

感謝

Answer 1

如果我理解正確的問題，是這樣的：

array_push($cats[0],'something else'); 

應該工作。
