如何在php中为数组分配一系列值？

我使用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.')'];
    }

果不其然，它将产生如下结果：

但我希望结果是这样的：

如何在PHP中实现这一点？

将数组赋值行更改为：

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

只要每个hash_id是唯一的，这将为每个路由创建一个新的数组元素

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

您可以通过以下方式添加第三个值：

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

换行

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

到

这样做：

$route_selection;
foreach ($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.')' ;
}

这不会产生他想要的输出，他会得到嵌套数组。是的。它起作用了。感谢您的快速解决方案。我是php数组的新手，非常感谢。谢谢。@JayMarz不要忘记接受最适合您的问题的答案，这样其他用户就可以节省时间，好的答案也会得到奖励。@ksjohn是的。还有6分钟检查答案。@JayMarz完美！抱歉，我没注意到问题这么年轻。这些问题回答得很快。@JayMarz没问题，很高兴我能帮上忙！

$route_selection;
foreach ($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.')' ;
