natsort()排列json数据时报错。

PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->$json = '[{"name":"a1"},{"name":"a10"},{"name":"a12"},{"name":"a3"},{"name":"a5"},{"name":"b21"},{"name":"b2"},{"name":"b11"}]';natsort($json);$data = json_decode($json);foreach ($data as $row) {    echo $row->name.'<br>';//}

为什么会提示 Warning: natsort() expects parameter 1 to be array, string given in d:\www\test.php?
另外natsort()和strnatcmp()的区别在哪里?
谢谢。


------解决方案--------------------
natsort 是数组排序函数,不能作用于字符窜

------解决方案--------------------
PHP code
$json = '[{"name":"a1"},{"name":"a10"},{"name":"a12"},{"name":"a3"},{"name":"a5"},{"name":"b21"},{"name":"b2"},{"name":"b11"}]';$data = json_decode($json);usort($data, 'cmp');function cmp($a, $b) {    if ($a->name == $b->name) return 0;    return $a->name > $b->name ? 1 : -1;}foreach ($data as $row) {    echo $row->name.'<br>';//}<div class="clear">
                 
              
              
        
            </div>
