DESCRIPTION

	Procedural style
       bool collator_sort_with_sort_keys (Collator  $coll, array  &$arr)

	Similar to collator_sort(3) but uses ICU sorting keys produced by ucol_getSortKey() to gain more speed on large arrays.

		-Array of strings to sort

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

	      <?php
	      $arr  = array( 'Kopfe', 'Kypper', 'Kopfe' );
	      $coll = collator_create( 'sv' );

	      collator_sort_with_sort_keys( $coll, $arr );
	      var_export( $arr );
	      ?>

	      The above example will output:
