                                    ?>
            使用说明:将上面的代码保存为1.php!
            
            1、在浏览器中输入http://你的网址/1.php?txt=文字  可直接观看效果
            2、在论坛中以这样的形式发帖:{img}http://你的网址/1.php?txt=文字{/img}(实际用时把大括号换为中括号)
            
            PS:如果你的空间不支持mb_convert_encoding函数,你需要有把gb2312转为utf-8的函数才能支持中文!
