Collator::asort - Sort array maintaining index association

       Object oriented style

SYNOPSIS
       public bool Collator::asort (array  &$arr, [int	$sort_flag])

DESCRIPTION
	Procedural style
       bool collator_asort (Collator  $coll, array  &$arr, [int  $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(3).

PARAMETERS
	      o $coll
		-Collator object.

	      o $arr
		-Array of strings to sort.

	      o $sort_flag
		- Optional sorting type, one of the following:

		     o Collator::SORT_REGULAR - compare items normally (don't change types)

		     o Collator::SORT_NUMERIC - compare items numerically

		     o 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.

RETURN VALUES
	Returns TRUE on success or FALSE on failure.

EXAMPLES
       Example #1

	      collator_asort(3)example

	      <?php
	      $coll = collator_create( 'en_US' );
	      $arr = array(
		   'a' => '100',
		   'b' => '50',
		   'c' => '7'
	      );
	      collator_asort( $coll, $arr, Collator::SORT_NUMERIC );
	      var_export( $arr );

	      collator_asort( $coll, $arr, Collator::SORT_STRING );
	      var_export( $arr );
	      ?>

	      The above example will output:

	      array (
		'c' => '7',
		'b' => '50',
		'a' => '100',
	      )array (
		'a' => '100',
		'b' => '50',
		'c' => '7',
	      )
