Описание тега asort

asort() takes in an array as argument and sorts this array while maintaining the index associations. Since the passed array is taken as pass-by-reference, the original array itself is updated/sorted.

Short Info

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. The function returns TRUE on success or FALSE on failure.

Usage

bool asort ( array &$array [, int $sort_flags = SORT_REGULAR ] )

• bool is the return value type.
• array is passed variable type.
• $sort_flags is optional parameter to modify sorting feature.

More information on the sort_flags is available here.

Miscellaneous
