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.
Equivalent to standard PHP asort().
Collator object.
Array of strings to sort.
Optional sorting type, one of the following:
Collator::SORT_REGULAR - compare items normally (don't change types)
Collator::SORT_NUMERIC - compare items numerically
Collator::SORT_STRING - compare items as strings
Default $sort_flag value is Collator::SORT_REGULAR. It is also used if an invalid $sort_flag value has been specified.
Devuelve TRUE si todo se llevó a cabo correctamente, FALSE en caso de fallo.
