如何筛选对象的数组？ [英] How to filter an array of object?
问题描述
我已经有了对象的数组（下面显示），我想编写一个返回同一阵列但随着对象（S）符合标准中删除的功能。
I've got an array of objects (show below) and I would like to write a function that returns the same array but with the "object(s)" that meet the criterion removed.
该函数将：
1检查
2-如果存在，为所需的值，并且如果对象的索引等于该值时，删除整个对象。检查
1- check if the index exists 2- if it exists, checks for the required value and if the object's index is equal to that value, remove the whole object.
例如：
Array
(
[course] => Array
(
[0] => stdClass Object
(
[name] => Programmation Web
[description] =>
[public] => 0
[requests] => 0
[id] => 245
[members] => Array
(
[0] => stdClass Object
(
[id] => 11
[name] => Robert Smith
)
)
[projects] => Array
(
[0] => stdClass Object
(
[id] => 1923
[title] => Sans titre (1)
[type] => portfolio
)
)
[project_count] => 1
[admins] => Array
(
[0] => stdClass Object
(
[member] => 11
[firstname] => Robert
[lastname] => Smith
)
)
[topic_name] => Le PHP
[activites] => Array
(
[0] => stdClass Object
(
[topic_name] =>
[topic_id] => 42
[post_parent] => 107
[post_body] => Oui moi aussi je me demande ça.
[post_id] => 109
)
)
[forums] => Array
(
[0] => stdClass Object
(
[forum_name] => Discussion générale
[forum_id] => 101
)
)
)
[1] => stdClass Object
(
[name] => Les bases de données
[description] =>
[public] => 0
[jointype] => controlled
[grouptype] => course
[membershiptype] => admin
[topic_name] => Difficulté
[activites] => Array
(
[0] => stdClass Object
(
[topic_name] =>
[topic_id] => 44
[post_parent] => 111
[post_body] => Ouah!
[post_id] => 112
)
)
[forums] => Array
(
[0] => stdClass Object
(
[forum_name] => Le MySQL
[forum_id] => 103
)
)
)
)
)
如果有一个对象，它的 admins->成员值等于11，取出对象，并没有这个对象返回数组。因此，返回数组将是：
If there's an object whose admins->member value is equal to 11, remove the object and return the array without this object. The returned array would thus be :
Array
(
[course] => Array
(
[0] => stdClass Object
(
[name] => Programmation Web
[description] =>
[public] => 0
[requests] => 0
[id] => 245
[members] => Array
(
[0] => stdClass Object
(
[id] => 11
[name] => Robert Smith (smithrobert)
)
)
[projects] => Array
(
[0] => stdClass Object
(
[id] => 1923
[title] => Sans titre (1)
[type] => portfolio
)
)
[project_count] => 1
[admins] => Array
(
[0] => stdClass Object
(
[member] => 11
[firstname] => Robert
[lastname] => Smith
)
)
[topic_name] => Le PHP
[activites] => Array
(
[0] => stdClass Object
(
[topic_name] =>
[topic_id] => 42
[post_parent] => 107
[post_body] => Oui moi aussi je me demande ça.
[post_id] => 109
)
)
[forums] => Array
(
[0] => stdClass Object
(
[forum_name] => Discussion générale
[forum_id] => 101
)
)
)
)
)
我怎么会去这样做？
How would I go about doing that ?
在此先感谢您的帮助！ ：O）
Thanks in advance for your help! :o)
推荐答案
要过滤数组？使用 array_filter ！
$new_array = array_filter($array, function($obj){
if (isset($obj->admins)) {
foreach ($obj->admins as $admin) {
if ($admin->member == 11) return false;
}
}
return true;
});
