PHP的:获得数组值而不通过它迭代? [英] php: get array value without iterating through it?

问题描述

我想我失去了理智.

print_r($ location); 列出一些地理数据.

array (
  'geoplugin_city' => 'My City',
  'geoplugin_region' => 'My Region',
  'geoplugin_areaCode' => '0',
  'geoplugin_dmaCode' => '0',
  'geoplugin_countryCode' => 'XY',
  'geopl ...

当我用foreach循环遍历它时，我可以打印每一行.但是，难道不能仅仅从数组中获取一个特定的值吗?

when I iterate through it with a foreach loop I can print each line. However shouldn't it be possible to just get a specific value out of the array?

like print $ location [g4]; 应该打印countryCode吗?谢谢！

like print $location[g4]; should print the countryCode shouldn't it? Thank you!

推荐答案

echo $location['geoplugin_countryCode'];
