上面代面什么意思啊，谁能解释一下
你那里能不能运行php? 如果能的话运行这一段就明白了:
<pre>
<?php
$a = array();
echo serialize($a); //显示 a:0{}
echo "<br />";
$b = 'a:3:{s:6:"config";a:7:{s:6:"expire";d:24;s:11:"expire_unit";s:4:"hour";s:11:"separate_by";i:0;s:15:"level_point_all";s:2:"5%";s:15:"level_money_all";s:2:"1%";s:18:"level_register_all";i:2;s:17:"level_register_up";i:60;}s:4:"item";a:4:{i:0;a:2:{s:11:"level_point";s:3:"60%";s:11:"level_money";s:3:"60%";}i:1;a:2:{s:11:"level_point";s:3:"30%";s:11:"level_money";s:3:"30%";}i:2;a:2:{s:11:"level_point";s:2:"7%";s:11:"level_money";s:2:"7%";}i:3;a:2:{s:11:"level_point";s:2:"3%";s:11:"level_money";s:2:"3%";}}s:2:"on";i:1;}';
var_export(unserialize($b));
?>
</pre>
