Question

我正在尝试将输出值从最大值返回到最小值。

以下是数组的示例：

array(
    'ACTION' => 'getsupportdepartments',
    'RESULT' => 'success',
    'TOTALRESULTS' => 2,
    'DEPARTMENTS' => array(
      'DEPARTMENT' => array(
        'ID' => 2,
        'NAME' => 'Sales',
        'AWAITINGREPLY' => 5,
        'OPENTICKETS' => 5
      ),
      'DEPARTMENT1' => array(
        'ID' => 1,
        'NAME' => 'Support',
        'AWAITINGREPLY' => 15,
        'OPENTICKETS' => 15

我正在使用的代码是：

if(!empty($_GET['sort'])) {
  $tmpArray = array();
  foreach($arr['WHMCSAPI']['DEPARTMENTS'] as $key => $value) {
    $tmpArray[$value['AWAITINGREPLY']] = $value;
  }
  $arr['WHMCSAPI']['DEPARTMENTS'] = $tmpArray;

  ($_GET['sort'] == 'desc') ? krsort($arr['WHMCSAPI']['DEPARTMENTS']) : ksort($arr['WHMCSAPI']['DEPARTMENTS']);
}


    ($_GET['sort'] == 'desc') ? krsort($arr['WHMCSAPI']['DEPARTMENTS']) : ksort($arr['WHMCSAPI']['DEPARTMENTS']);

  foreach($arr['WHMCSAPI']['DEPARTMENTS'] as $department) {
    echo $department['NAME'].' - '.$department['AWAITINGREPLY'].'<br />';
 }
  echo $exc;

然而，AWAITINGREPLY的输出顺序不是排序。

无需重新发明轮子，已经有一个名为usort的功能：

online demo

function sortDepts(array &$arr,$sort="desc")
{
    if($sort=="desc")
        usort($arr["DEPARTMENTS"],function($a,$b){
            return $b["AWAITINGREPLY"]-$a["AWAITINGREPLY"];
        });
    else
        usort($arr["DEPARTMENTS"],function($a,$b){
            return $a["AWAITINGREPLY"]-$b["AWAITINGREPLY"];
        });
    return $arr;
}

请注意，匿名函数适用于PHP＆gt; = 5.3。如果你需要支持5＆lt; = PHP＆lt; 5.3，你需要先声明该函数。

修改：

对于5＆lt; PHP＆lt; 5.3：

online demo

function asc($a,$b) { return $a["AWAITINGREPLY"]-$b["AWAITINGREPLY"]; } function desc($a,$b) { return $b["AWAITINGREPLY"]-$a["AWAITINGREPLY"]; } function sortDepts(array &$arr,$sort="desc") { if($sort=="desc") usort($arr["DEPARTMENTS"],"desc"); else usort($arr["DEPARTMENTS"],"asc"); return $arr; }

修改＃2：

如果您仍需要密钥（DEPARTMENT，DEPARTMENT1等），请使用uasort代替usort（不需要更改其他代码）。< / p>
