PHP数组问题，array_merge() foreach重复问题

Question

How to solve array problem?如何解决数组问题？

$kuponlar = $core->query("SELECT * FROM kupon WHERE kupon_durum = ?", array(0));

if ($kuponlar) {

        foreach($kuponlar as $data) {

            $mac = json_decode($data['kupon_detay']);

            if (isset($mac)) {
                $output = array();
                foreach ($mac as $key) {
                    if (isset($maclar[$key->mac_kod])) {
                        $maclists=$db->prepare("SELECT * FROM maclar WHERE mac_id=?");
                        $maclists->execute(array($key->mac_id));
                        $maclist=$maclists->fetch(PDO::FETCH_ASSOC);

                        $date = strtotime($maclist['mac_zaman']." ".$maclist['mac_saat']);

                        if ($date < time()) {

                            $idsi = $key->mac_uniq;

                            $skor = $maclar[$key->mac_kod];
                            $sonuc = $core->result($donustur[$key->tahmin], $skor,$key->mac_kod);

                            $resultArray =  (array) $mac->$idsi;

                            $new_data = array('durum' => $sonuc);
                            $kupon = array_replace($resultArray, $new_data);
                            $veri = array($maclist['mac_uniq'] => $kupon);
                            $tekrar = array_replace($veri);

                            $output = array_merge($output, $tekrar);

                            echo "<pre>";
                            print_r($output);
                            echo "</pre>";
                        }
                    }
                }
            }
        }
    }

Desired output期望输出

Output To Me输出给我

$output = array_merge($output, $tekrar);

I think I've made a problem here but I get the same result in which way I tried我想我在这里遇到了问题，但我尝试的结果相同

The problem is not in array_merge but in the printing part.问题不在于array_merge而在于打印部分。 You simply need to move the printing out from the foreach loop.您只需要将打印从 foreach 循环中移出即可。 You are printing the $output array every time you iterate over your result set.每次迭代结果集时，您都在打印$output数组。

Do this once after the foreach loop to get the desired output.在 foreach 循环之后执行此操作以获得所需的输出。

foreach ($mac as $key) {
    //..
}
echo "<pre>";
print_r($output);
echo "</pre>";

Update :更新：

foreach ($mac as $key) {
    //..
}
// if you want to print only non-empty results
if (!empty($output)) {
    echo "<pre>";
    print_r($output);
    echo "</pre>";
}
