Php 数组到格式化文本键：值

Question

我有这个数组：

Array ( [location] => Array ( [country] => India [country_code] => IN [region] => [region_code] => [city] => [zip] => [latitude] => 13.044468 [longitude] => 77.575665 [ip_address] => 123.236.219.154 [timestamp] => 1317496122 [route] => 3rd Cross Rd [neighborhood] => Basaveshwara Layout [sublocality] => BCITS PVT LTD [locality] => Bengaluru [administrative_area_level_2] => Bengaluru Rural [administrative_area_level_1] => Karnataka ) ) 

我想知道是否有一种方法可以将其格式化，如下所示：

country: India
country_code:In

就像 键：值， 键：值， 键：值

Answer 1

类似的事情？

foreach( $array as $key => $value ) {
  echo $key." : ".$value.",";
}

您必须检查最后一个值并删除“，”。
