如何从STDObject中删除数组？

Hello!!

i think its very simple question for those who familier with std objects and arrays in PHP.

对于那些熟悉PHP中的std对象和数组的人来说,我认为这是一个非常简单的问题。

Here is my STD Object array:

这是我的STD对象数组:

Array ( [0] => stdClass Object ( [name] => name1 [description] => [category_id] => 17 [category_publish] => 1 [ordering] => 1 [category_parent_id] => 10 ) [1] => stdClass Object ( [name] => name2 [description] => [category_id] => 8 [category_publish] => 1 [ordering] => 1 [category_parent_id] => 0 ) [2] => stdClass Object ( [name] => name3 [description] =>desc [category_id] => 10 [category_publish] => 1 [ordering] => 2 [category_parent_id] => 0 ) [3] => stdClass Object ( [name] => name3 [description] => [category_id] => 16 [category_publish] => 1 [ordering] => 2 [category_parent_id] => 10 ) )

now, i have different array with numbers for example:

现在,我有不同的数字数组,例如:

$arr=array(17,10);

and i need to check if one of this numbers is equal the [category_id] value (inside the std object), if it is equal, check the next [category_id], and if it's not, remove all values of this object . (of course, Other method is to build a new STD Object only with the numbers in the array)

我需要检查其中一个数字是否等于[category_id]值(在std对象内),如果相等,检查下一个[category_id],如果不相等,则删除该对象的所有值。 (当然,其他方法是仅使用数组中的数字构建新的STD对象)

So the result should be:

所以结果应该是:

Array ( [0] => stdClass Object ( [name] => name1 [description] => [category_id] => 17 [category_publish] => 1 [ordering] => 1 [category_parent_id] => 10 ) [2] => stdClass Object ( [name] => name3 [description] =>desc [category_id] => 10 [category_publish] => 1 [ordering] => 2 [category_parent_id] => 0 ) )

Only the array's with categiry_id =17 and 10 are inside this stdObject..

只有带有categiry_id = 17和10的数组才在此stdObject中。

Thank you very much for your help!!

非常感谢您的帮助!!

#1

Try this

$arr=array(17,10);
foreach ($array as $key => $obj) {
  if (!in_array($obj->category_id, $arr)) {
    unset($array[$key]);
  }
} 
// edited, missing closing bracket

You can use array_filter to filter what you want or what you don't want

您可以使用array_filter过滤您想要的或您不想要的内容

$filterCategory = array(17,10);
$array = array_filter($yourArray,function($var) use($filterCategory) { return in_array($var->category_id, $filterCategory); } );
