foreach在具有匹配属性的对象数组上

Question

I have an array of objects I'm using to create a menu, and each object has the properties id, video_id and chapter_id.

I'd like to make a for each loop such as

foreach($menu_objects as $object WHERE $object->chapter == $variable)

Is there a way of doing this?

PHP doesn't offer syntax like that, however, you could always make it an if-statement as the first line in the loop:

foreach ($menu_objects as $object) {
    if ($object->chapter != $variable) continue;
    ... process as normal ...
