- PHP code
$json = '[{"name":"a1"},{"name":"a10"},{"name":"a12"},{"name":"a3"},{"name":"a5"},{"name":"b21"},{"name":"b2"},{"name":"b11"}]';natsort($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
