已经在所有页面设置header为utf-8。乱码导致没办法和数据里的数据就行比较，和原文不相等了。
找到原因，因为写入数据库用函数mysql_real_escape()进行了处理，而取出没有进行反向处理导致中文乱码，使用stripslashes()进行处理后读出正常。
首先你你应该看下文件编码，如果文件编码是gbk，header也木用，header只是告诉客户端以下内容按照utf8解析，跟文件或者内容本身编码无关，至于数据库会不会乱码，这个跟字符集范围有关系，数据库会不会乱码可以举个例子：如果文件是gbk编码，数据库字段是utf8，存储的时候set names utf8,读取出来在utf8的文件中展示的时候设置charset是utf8,我的理解是不会乱码的，因为gbk的字符集范围比utf8小，gbk内容以utf8编码是可以存储下的，而以utf8存储再以utf8展示是不会乱码的，如果以gbk读出来我觉得是会乱码的，虽然文件是gbk，但是是以utf8存储在数据库的，而utf8是占三字节或以上，而gbk是两个字节，所以gbk展示不了utf8的内容，所以会乱码，纸上谈兵，没有实践过，在此谬论，我只是说我是这么理解的！
