假设有这个数组:
Array
(
[0] => Array
(
[title] => this is the newest post
[ssm_featured_post_id] => 70
)
[1] => Array
(
[title] => sdfsfsdf
[ssm_featured_post_id] => 63
)
[2] => Array
(
[title] => test
[ssm_featured_post_id] => 49
)
[3] => Array
(
[title] => Hello world!
[ssm_featured_post_id] => 1
)
ssm_featured_post_id的值对应于第二个数组中的数组项的值。我想按照第二个数组中的项的顺序排序第一个数组中的项。
Array
(
[1] => 63
[0] => 70
[3] => 1
[2] => 49
)
因此,排序后的结果将会是:
Array
(
[0] => Array
(
[title] => sdfsfsdf
[ssm_featured_post_id] => 63
)
[1] => Array
(
[title] => this is the newest post
[ssm_featured_post_id] => 70
)
[2] => Array
(
[title] => Hello world!
[ssm_featured_post_id] => 1
)
[3] => Array
(
[title] => test
[ssm_featured_post_id] => 49
)
)
