Collator::sortWithSortKeys -- collator_sort_with_sort_keys — Sort array using specified collator and sort keys
Object oriented style
Procedural style
Similar to collator_sort() but uses ICU sorting keys produced by ucol_getSortKey() to gain more speed on large arrays.
Returns TRUE on success or FALSE on failure.
Example #1 collator_sort_with_sort_keys() example
<?php
$arr = array( 'Köpfe', 'Kypper', 'Kopfe' );
$coll = collator_create( 'sv' );
collator_sort_with_sort_keys( $coll, $arr );
var_export( $arr );
?>
The above example will output:
array ( 0 => 'Kopfe', 1 => 'Kypper', 2 => 'Köpfe', )
