在PHP中組合子數組

我想按鍵組合數組。因此，所有以相同子密鑰開始的子數組將被組合成一個子數組。另外，我想保留匹配值的最小值。在PHP中組合子數組

目前，這是我所：

$statement = Array 
(
    [662_0] => Array 
     (
      [0] => 06-01-2012 
      [1] => 436 
      [2] => MEDIA 
      [3] => 2006 
      [4] => Template Testing 
      [5] => KS 
      [6] => 662 
      [7] => 0 
      [8] => 0 
      [9] => 0 
      [10] => 0 
      [11] => 0 
      [12] => 1290 
      [13] => 1290.00 
      [14] => 0.00 
      [15] => 0 
      [16] => 1290.00 
     ) 

    [662_1] => Array 
     (
      [0] => 06-01-2012 
      [1] => 436 
      [2] => MEDIA 
      [3] => 2006 
      [4] => Template Testing 
      [5] => KS 
      [6] => 662 
      [7] => 295.00 
      [8] => 0 
      [9] => 0 
      [10] => 0 
      [11] => 0 
      [12] => 995 
      [13] => 1290.00 
      [14] => 0.00 
      [15] => 0 
      [16] => 1290.00 
     ) 

    [662_2] => Array 
     (
      [0] => 06-01-2012 
      [1] => 436 
      [2] => MEDIA 
      [3] => 2006 
      [4] => Template Testing 
      [5] => KS 
      [6] => 662 
      [7] => 0 
      [8] => 0 
      [9] => 0 
      [10] => 0 
      [11] => 0 
      [12] => 1290 
      [13] => 1290.00 
      [14] => 0.00 
      [15] => 0 
      [16] => 1290.00 
     ) 

    [663_0] => Array 
     (
      blah blah blah... 
     ) 
);

這是我想擁有的一切：

$statement = Array 
(
    [662] => Array 
     (
      [0] => 06-01-2012 
      [1] => 436 
      [2] => MEDIA 
      [3] => 2006 
      [4] => Template Testing 
      [5] => KS 
      [6] => 662 
      [7] => 295.00 
      [8] => 0 
      [9] => 0 
      [10] => 0 
      [11] => 0 
      [12] => 995 
      [13] => 1290.00 
      [14] => 0.00 
      [15] => 0 
      [16] => 1290.00 
     ) 

    [663] => Array 
     (
      blah blah blah... 
     ) 
);

快樂需要時提供更多信息！謝謝！！！

爲什麼標記爲[tag：mysql]？數據來自MySQL查詢嗎？也許最簡單的解決辦法是從那個方面改變它？ – eggyal

你到目前爲止嘗試過什麼來排序和合並數組並返回結果？ – Jrod

eggyal：是的，數據是從MySQL查詢填充的。我有/正在改變這方面的方法以及.http：//stackoverflow.com/questions/10983362/combine-results-for-sql-query Jrod：我已經嘗試array_merge，array_multisort，並與implode組合但無法獲得理想的結果。我添加了任何有用的信息，但是有很多，這就是爲什麼我沒有把它全部放到一開始。謝謝！ – Drewness

此代碼迭代您的原始數組，削減_以獲取項目的組合標識符並將它們合併在一起，如果新值小於已設置的值，則替換結果數組中的值。

<?php 
$original = array(
     '122_0' => array('k1'=>4, 'k2'=>2), 
     '122_1' => array('k2'=>3, 'k3'=>3), 
     '122_2' => array('k3'=>2, 'k4'=>4), 
     '111_0' => array('k1'=>3, 'k2'=>3), 
     '111_1' => array('k2'=>2, 'k3'=>2), 
     '111_2' => array('k3'=>1, 'k4'=>1) 
); 

foreach ($original as $key=>$sub) { 
    list($realkey, $num) = explode('_', $key); 
    foreach ($sub as $subkey => $value) { 
     if (isset($result[$realkey][$subkey]) 
      && $value < $result[$realkey][$subkey]) { 
      $result[$realkey][$subkey] = $value; 
     } 
    } 
} 
print_r($result);

這太棒了！我很接近！但由於某種原因，我的'print_r（$ result）;'是空白的。有什麼想法嗎..？ – Drewness
