没有mysql按键值排序数组

Question

如何在没有MYSQL订单的情况下对数组进行排序？

我有一个名为sort的键值，这是1,2,3,0等。我打印的数组没问题，但我需要根据排序值将此数组从低到高排序。我怎么能这样做？

    foreach($res as $key=>$value){
        $res[$key]['subaddonsname'] = $this->getValue("addonsname",$CFG['table']['addons'],"id = '".$res[$key]['menuaddons_addonsname']."' ");
        $newArr[$key]['subaddonsort'] = $this->getValue("addonsort",$CFG['table']['addons'],"id = '".$res[$key]['menuaddons_addonsname']."' ");
    }

    echo "<pre>";print_r($res);echo "</pre>";exit();

此结果

Array

Answer 1

您也可以这样做

usort($res, function($a, $b) {
    if ($a['subaddonsort'] == $b['subaddonsort']) return 0;
    return $a['subaddonsort'] < $b['subaddonsort'] ? -1 : 1;
});

Answer 2

PHP的sort functionality非常适合所有场合。

鉴于您的问题和PHP文档的详细信息，您似乎需要使用asort()函数：

asort($res);

die('<pre>' . print_r($res, true) . '</pre>');
