按相同的數組鍵旁邊

Question

問題是這樣的...

現有陣列：

Array(
    [0] => array('sample 1', 'sample 2') 
    [1] => array('cat', 'dog') 
) 

另一個數組：

Array(
    [0] => array('sample 3', 'sample 4') 
) 

我想發生什麼將其添加到0鍵旁邊使其成爲：

Array(
    [0] => array('sample 1', 'sample 2') 
    [1] => array('sample 3', 'sample 4') 
    [2] => array('cat', 'dog') 
) 

你是如何做到這一點的？

@maxhud 我嘗試過，但其結果是這樣的：

Array(
[0] => sample 1 
[1] => sample 2 
[2] => sample 3 
[3] => sample 4 
[4] => cat 
[6] => dog 
) 

這裏是我當前的電流的代碼片段

$new_post_order = array(); 
foreach($the_query['posts'] as $the_post) { 
$portfolio_reorder = ''; 
$portfolio_reorder = get_post_meta($the_post['ID'], 'portfolio_reorder', true); // Get the order on the db 
if(empty($portfolio_reorder)) { // If its empty... 
$portfolio_reorder = 0; // Add default order       
} 
array_splice($new_post_order, $portfolio_reorder, 0, $the_post); 
} 

echo '<pre>'; 
print_r($new_post_order); 
echo '</pre>'; 

Answer 1

您與array_splice做到這一點：

http://php.net/manual/en/function.array-splice.php

Ex充足的：

$input = array("red", "green", "blue", "yellow"); 
array_splice($input, 3, 0, "purple"); 
// $input is now array("red", "green", 
//   "blue", "purple", "yellow"); 

請自己試一試，如果您無法弄清楚，請發表評論，我們會幫您解決。

array_splice($new_post_order, $portfolio_reorder, 0, array($the_post));
