如何使用特定鍵對數組進行排序

我想根據MYCOUNT索引對我的數組行進行排序，該索引由我的代碼計算得出。 MYCOUNT計算的匹配字數關鍵字。我有谷歌不同的功能，但我從來沒有得到所需的結果。我是新的PHP我不知道如何做到這一點，我從來沒有在谷歌上找到可以幫助我的結果。如何使用特定鍵對數組進行排序

$word = "red pent"; 
$flag = true; 
$main_flag = true; 
$list = array(); 
$result = $this->db->get('products')->result_array(); 
foreach ($result as $product): 
    $main_flag = true; 
    $keywords = explode(';', $product['product_keyword']); 
    $count = 0; 
    foreach ($keywords as $keys) { 
     $search = explode(' ', $word); 
     $local_f = false; 
     foreach ($search as $w) { 
      if (strtolower(trim($w)) === strtolower(trim($keys))) { 
       $local_f = true; 
       $count++; 
       break; 
      } 
     } 
    } 
    if ($count > 0) { 
     $product['mycount'] = $count; 
     array_push($list, $product); 
    } 
    if ($main_flag) { 
     //array_push($list,$product); 
    } 
endforeach;

陣列數據

當你要根據你使用the sorting functions，使「用戶自定義」分類用戶定義的標準，如uasort排序：

function sortby_mycount_asc($a, $b) { 
    return $a["mycount"] - $b["mycount"]; 
} 
uasort($product, "sortby_mycount_asc");

它在我的情況下工作

function cmp($a, $b) { 

     if ($a['mycount'] == $b['mycount']) { 
      return 0; 
     } 
     return ($a < $b) ? 1 : -1; 
    } 

    uasort($list,"cmp");
