如何在php中为数组分配一系列值？

Question

我正在使用foreach循环为数组赋值。

$route_selection;
    foreach ($routes as $route) {
        $from_state = $route->fromState->name;
        $to_state = $route->toState->name;
        $from_country = $route->fromCountry->name;
        $to_country = $route->tocountry->name; 
        $route_selection[] = [$route->hash_id => 'From: '.$from_state.' ('.$from_country.') To: '.$to_state.' ('.$to_country.')'];
    }

果然，它会产生这样的结果：

但我希望结果是这样的：

我怎么能用PHP做到这一点？

Answer 1

将阵列分配线更改为：

$route_selection[$route->hash_id] = 'From: '.$from_state.' ('.$from_country.') To: '.$to_state.' ('.$to_country.')';

只要每个hash_id都是唯一的，这将为每条路线创建一个新的数组元素。

Answer 2

$array => array(pWjY=>'Value',
                YA8N=>'Value',);

您可以添加第三个值：

$array['somekey'] = 'Value';

Answer 3

更改此行

$route_selection[] = [$route->hash_id => 'From: '.$from_state.' ('.$from_country.') To: '.$to_state.' ('.$to_country.')'];

到

$route_selection[$route->hash_id] =  'From: '.$from_state.' ('.$from_country.') To: '.$to_state.' ('.$to_country.')';
