wp_filter_object_list( array $list, array $args = array(), string $operator = 'and', bool|string $field = false )

Filters a list of objects, based on a set of key => value arguments.


Description Description

Retrieves the objects from the list that match the given arguments. Key represents property name, and value represents property value.

If an object has more properties than those specified in arguments, that will not disqualify it. When using the ‘AND’ operator, any missing properties will disqualify it.

When using the $field argument, this function can also retrieve a particular field from all matching objects, whereas wp_list_filter() only does the filtering.
