collator_asort — Sort array maintaining index association

Description

Object oriented style

bool Collator::asort ( array &$arr [, integer $sort_flag ] )

Procedural style

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

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().
