我有一个来自 WordPress 的数组get_posts()
功能。
$posts:
array(15) {
[0]=>
object(WP_Post)#285 (24) {
["ID"]=>
int(253)
["post_author"]=>
string(1) "1"
["post_date"]=>
string(19) "2014-04-17 18:36:27"
["post_date_gmt"]=>
string(19) "2014-04-17 18:36:27"
["post_content"]=>
string(8) "gsdljdkf"
["post_title"]=>
string(10) "Shortcoded"
["post_excerpt"]=>
string(0) ""
["post_status"]=>
string(7) "publish"
["comment_status"]=>
string(6) "closed"
["ping_status"]=>
string(4) "open"
["post_password"]=>
string(0) ""
["post_name"]=>
string(12) "shortcoded-2"
["to_ping"]=>
string(0) ""
["pinged"]=>
string(0) ""
["post_modified"]=>
string(19) "2014-04-17 18:36:27"

["post_content_filtered"]=>
string(0) ""
["post_parent"]=>
int(0)
["guid"]=>
string(51) "http://XXX.0.0.1:4001/wordpress/board/shortcoded-2/"
["menu_order"]=>
int(0)
["post_type"]=>
string(10) "board_post"
["post_mime_type"]=>
string(0) ""
["comment_count"]=>
string(1) "0"
["filter"]=>
string(3) "raw"
}
[1]=>
object(WP_Post)#284 (24) {
(so on and so forth for all posts)
}
我有一个包含要排除的帖子 ID 的数组。
$ids_of_posts_to_exclude:
array(3) {
[0]=> string(253)
[1]=> string(456)
[2]=> string(789)
}
如何删除其中列出了 id 的帖子$ids_of_posts_to_exclude
from $posts
?
您可以使用 foreach 循环和in_array()
功能。像这样:
foreach($posts as $key => $post) {
// if post id is inside the ids of posts to be excluded
if(in_array($post->ID, $ids_of_posts_to_exclude)) {
unset($posts[$key]); // remove that key
}
}
