php arrays multidimension

Question

我剛剛製作了一個刮腳本，它的工作原理。現在我得到這樣的輸出：

Array 
(
    [0] => Array 
     (
      [0] => example stuff 
      [1] => example stuff 
      [2] => example stuff 
      [3] => example stuff 
     ) 

[1] => Array 
    (
     [0] => /spellen/thumbs/a/aladdinwildride_6524.jpg 
     [1] => /spellen/thumbs/t/toystory3_3476.jpg 
     [2] => /spellen/thumbs/f/fred-flintstone-bobsled_2180.jpg 
     [3] => /spellen/thumbs/m/madagascar-2.jpg 
    ) 

[2] => Array 
    (
     [0] => spel Alladin Wide Rit 
     [1] => spel Toy Story 3 
     [2] => spel Bedrock Bobsledding blowout 
     [3] => spel Madagascar 2 Ontsnap naar Afrika 

    ) 

[3] => Array

     [3] => /spellen/cartoons/237/madagascar-2-ontsnap-naar-afrika.html 

    ) 

[4] => Array 
    (
     [0] => l 
     [1] => l 
     [2] => l 
     [3] => l 

    ) 

[5] => Array 
    (
     [0] => Speel Alladin Wide Rit online 
     [1] => Speel Toy Story 3 online 
     [2] => Speel Bedrock Bobsledding blowout online 
     [3] => Speel Madagascar 2 Ontsnap naar Afrika online 

    )

     [1] => e 
     [2] => e 
     [3] => e 

    ) 

[7] => Array 
    (
     [0] => /images/thumb_frame_top.gif 
     [1] => /images/thumb_frame_top.gif 
     [2] => /images/thumb_frame_top.gif 
     [3] => /images/thumb_frame_top.gif 

    ) 

[8] => Array 
    (
     [0] => f 
     [1] => f 
     [2] => f 
     [3] => f 

    ) 

）

現在我想一個簡單的foreach返回我的每$matches[1][0]，$matches[2][0]和$matches[3][0]。

我一直試圖讓這個小時，但沒有運氣。有誰能夠幫助我？

Answer 1

$result = array(); 
foreach ($matches as $match) { 
    $result[] = array(
     $match[1], 
     $match[2], 
     $match[3], 
    ); 
    // or unset($match[0]); if you don't need the original array anymore 
    // or array_splice($match, 0, 1); if you also want to rearrange the keys 
} 

Answer 2

foreach($matches as $match){ 

    // $match[0] is what you need 

} 

如果你想要的結果包裹在一個新的數組，可以減少原來的數組：

$newArray = array_reduce($matches, function(&$result, $match){ 

    $result[] = $match[0]; 

}); 

Answer 3

是這是你想要的嗎？

for ($i = 0; $i < count($matches); $i++) 
{ 
    print $matches[$i][0]; 
} 

Answer 4

foreach ($matches as $j => $match) { 
    foreach ($match as $i => $mi) { 
     if ($i != 0) unset($matches[$j][$i]); 
    } 
} 

Answer 5

如果只想前三：

$newArray = array(
    $matches[1][0], 
    $matches[2][0], 
    $matches[3][0] 
); 

結果：

Array 
    (
     [0] => /spellen/thumbs/a/aladdinwildride_6524.jpg 
     [1] => spel Alladin Wide Rit 
     [2] => /spellen/cartoons/2096/alladin-wide-rit.html 
    )
