从json数组PHP获取数组值

标签： php arrays json google-maps

我正在使用google place json array

我正在使用此代码获取地点名称

 $string = file_get_contents("https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522,151.1957362&rankby=distance&types=food&key=AIzaSyCpOG91fkAzPTZiFq7G9HbLfbmVyW8Wgyc");
$json_a = json_decode($string, true);

echo print_r(array_values($json_a-> results[0]->name[0]));

但结果总是{ 1 }，结果应为 Biaggio Cafe

如果我打印出数组 print_r（$ json_a）

2 个答案:

echo print_r(....);在某种程度上是多余的。 print_r它会以与echo类似的方式将结果自行打印到输出，并返回您正在打印的TRUE。

来自documentation：

mixed print_r ( mixed $expression [, bool $return = false ] )
当return参数为TRUE时，此函数将返回一个字符串。否则，返回值为TRUE。

要么不使用echo，要么将返回参数设置为TRUE。

echo print_r($array, true);

答案 1 :(得分：0)

检查从调用中获取的json的结构，以便访问您想要执行的值。

$string = file_get_contents("https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522,151.1957362&rankby=distance&types=food&key=AIzaSyCpOG91fkAzPTZiFq7G9HbLfbmVyW8Wgyc");
$json_a = json_decode($string, true);

print_r($json_a['results'][0]['name']));

结果是一个数组，您想要访问其第一个元素（[0]）。从第一个元素中获取属性名称。并且元素上的所有属性都在数组中设置，因此您需要通过属性名称来访问它。

您使用对象运算符（->）来访问数组中的元素，这就是它无效的原因。
