Laravel list()with each()函数错误，函数已弃用 [英] Laravel list() with each() function error with deprecated function

问题描述

由于不推荐使用each()函数，我对此有些困惑，因为我已经意识到这一点，并修复了我项目中的某些while( list() = each() )错误情况.但是，在这种情况下，我还应该使用什么其他选项:

I get a little confuse here on how to alternatively replace the each() function since it was deprecated and I'm aware of that and fixed some of the while( list() = each() ) error case in my project. However, what other option should I use for this case:

foreach($new_id as $new_ids) {
    list($key,$valueAddress) = each($address);
    list($key,$valueCity) = each($city);
    list($key,$valueState) = each($state);
    if(isset($_POST['publicOnly'])) {
        list($key,$valuePublicOnly) = each($publicOnly);
    } else {
        $valuePublicOnly = 0;
    }

    $propertyAddress = PropertyAddressManagement::find($new_ids);
        $propertyAddress->address = $valueAddress;
        $propertyAddress->city = $valueCity;
        $propertyAddress->state = $valueState;
        $propertyAddress->publicOnly = $valuePublicOnly;
    $propertyAddress->save();
}

推荐答案

您不使用键，因此只需获取当前值，然后移至下一个键即可:

You're not using the keys so just get the current value and then move to the next one:

foreach($new_id as $new_ids) {
    $propertyAddress = PropertyAddressManagement::find($new_ids);
        $propertyAddress->address = current($address);
        $propertyAddress->city = current($city);
        $propertyAddress->state = current($state);
        $propertyAddress->publicOnly = isset($_POST['publicOnly']) ? current($publicOnly) : 0;
    $propertyAddress->save();

    next($address); next($city); next($state); next($publicOnly);
}

但是，如果键在所有数组中都相同，那么我认为这确实应该起作用:

However, if the keys are the same in all of the array then I think really this should work:

foreach($new_id as $key => $new_ids) {
    $propertyAddress = PropertyAddressManagement::find($new_ids);
        $propertyAddress->address = $address[$key];
        $propertyAddress->city = $city[$key];
        $propertyAddress->state = $state[$key];
        $propertyAddress->publicOnly = isset($_POST['publicOnly']) ? $publicOnly[$key] : 0;
    $propertyAddress->save();
}
