我正在尝试从数组中输出特定值,但是每次运行数组时该值都在不同的位置,如下所示:
在一页上:
Array
(
[id] => 12445
[countries] => Array
(
[0] => Array
(
[iso_3166_1] => GB
[certification] => 12A
[release_date] => 2011-07-07
)
[1] => Array
(
[iso_3166_1] => US
[certification] => PG-13
[release_date] => 2011-07-15
)
[2] => Array
(
[iso_3166_1] => DE
[certification] => 12
[release_date] => 2011-07-12
)
}
在另一页上:
Array
(
[id] => 673
[countries] => Array
(
[0] => Array
(
[iso_3166_1] => US
[certification] => PG
[release_date] => 2004-06-04
)
[1] => Array
(
[iso_3166_1] => GB
[certification] => PG
[release_date] => 2004-05-31
)
[2] => Array
(
[iso_3166_1] => IT
[certification] => T
[release_date] => 2004-06-04
)
}
如您所见,一页上的“GB”字符串位于数组中的位置 0,而在另一页中,它位于位置 1。现在,此代码部署到的页面是动态的,所以我可以t just hard-code $array['countries'][0]['release_date']
,其中'release_date'是我想从数组中提取的实际值,所以我想我需要代码来搜索数组中的'GB'(或'US',或其他country 需要返回),找到包含该字符串的索引号并将其作为 $uk_release_date 或某些此类命名变量动态地放入查询中。
提前致谢!
