collator_asort ( Collator $coll , array &$arr [, int $sort_flag ] ) : bool

This function sorts an array such that array indices maintain their correlation with the array elements they are associated with. This is used mainly when sorting associative arrays where the actual element order is significant. Array elements will have sort order according to current locale rules.
