我正在使用Google Maps地理编码API发送部分地址并接收完整的地址信息。
Google的API在基于其能够匹配的部分地址的数据返回结果的方式上不一致,特别是" address_components"字段中的对象数(ex:有时它将包括'commission_area_lea_level_2',在这种情况下,"国王县")。
我有没有办法使用"类型"字段作为标识符检索特定的" address_component"数据?否则,似乎我必须执行一系列手动检查以确定Google返回了多少个地址_COMPONENTS。
我感兴趣的JSON响应的部分是:
{
"results":[
{
"address_components":[
{
"long_name":"125",
"short_name":"125",
"types":[
"street_number"
]
},
{
"long_name":"Court Street",
"short_name":"Court St",
"types":[
"route"
]
},
{
"long_name":"Brooklyn",
"short_name":"Brooklyn",
"types":[
"political",
"sublocality",
"sublocality_level_1"
]
},
{
"long_name":"Kings County",
"short_name":"Kings County",
"types":[
"administrative_area_level_2",
"political"
]
},
{
"long_name":"New York",
"short_name":"NY",
"types":[
"administrative_area_level_1",
"political"
]
},
{
"long_name":"United States",
"short_name":"US",
"types":[
"country",
"political"
]
},
{
"long_name":"11201",
"short_name":"11201",
"types":[
"postal_code"
]
}
],
非常感谢。
<?php
$addr = json_decode('{json here..}', true);
/**

* @param string $type
* @param array $from
* @return string|array|null

function getByType($name, $type, array $from)
{
foreach($from as $values) {
if (in_array($type, $values['types'])) {
return $values[$name] ?: $values;
}
}
return null;
}
var_dump(getByType('long_name', 'route', $addr['results'][0]['address_components']));

您可以编写一个函数来检索给定类型的组件对象。这样的东西:
$components = ...; // The JSON decoded "address_components" array
/**
* Get a component by type.
*
* @param {string} $type The component type. E.g. 'street_number'.
* @return {null|object} The desired component or null in case there's no
* component for the given type.
*/
$componentByType = function ($type) use ($components) {
$found = array_filter($components, function ($component) use ($type) {
return in_array($type, $component->types);
});
return reset($found);
};
使用问题的回答,以下代码...
$component = $componentByType('route');
echo $component->long_name;
...将输出:
