示例 #1 collator_asort() 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 );
?>
以上例程會(huì )輸出：
array ( 'c' => '7', 'b' => '50', 'a' => '100', )array ( 'a' => '100', 'b' => '50', 'c' => '7', )
