从json选择选项php获取变量

Question

我在 php 中有一个带有 foreach 的 JSON 解码数组，每次我从这个下拉列表中选择一个选项时，它都会在表单中包含一个选择选项，它会返回列表中的最后一个值。我正在尝试保存 flatnumber、building、address1 变量。我该怎么办？

    $api_url = 'http://rest.api?postcode=' . urlencode($_GET['postcode']);
    $api_json = file_get_contents($api_url);
    $api_array = json_decode($api_json, true);
    $address = $api_array['addresses'];
    foreach($address as $addresses){
    echo '<option>'.$addresses['address'].'</option>';
        $flatnumber = $addresses['flatNumber'];
        $address1 = $addresses['building'];
        $address2 = $addresses['address1'];
        $town = $addresses['town'];
        $county = $addresses['county'];
    }

这是数组：

Answer 1

我所做的就是将所有值放入选项值中，提交表单，然后在提交后分解值。

        $result = $_POST['address1'];
        $result_explode = explode('|', $result);
        $flatnumber = $result_explode[0];
        $building = $result_explode[1];
        $street = $result_explode[2];


        <form method="post">
            <select name="address1">
        foreach($address as $addresses){
            echo '<option value="'.$addresses['flatNumber'].'|'.$addresses['building'].'|'.$addresses['address1'].'|'.$addresses['knownElectricityMeter'].'|'.$addresses['knownGasMeter'].'">'.$addresses['flatNumber'].' '.$addresses['building'].' '.$addresses['address1'].'</option>';  
        }
            </select>
        </form>
