gb2312的php文件转换为utf-8格式后的一个错误_PHP
GB2312的php文件转换为UTF-8格式后，php程序运行时就会出现header已发送这样的错误提示（试图打开session的时候）。
错误如下：
代码:
| Warning: Cannot modify header information - headers already sent by (output started at /home/yoyo/public_html/blog/index.php:1) in /home/yoyo/public_html/blog/global.php on line 11 ? Warning: Cannot modify header information - headers already sent by (output started at /home/yoyo/public_html/blog/index.php:1) in /home/yoyo/public_html/blog/global.php on line 35 |
这样的错误通常是在打开session之前页面已经有输出时出现，在IE下面看，并没有输出，可是在firefox下面看，在正式页面输出前，有一个字节的乱码。这个乱码就是造成错误的原因（它在session之前就输出了）。
解决的方法：找到你有出错提示的文件，下载下来，用编辑器（推荐用最新版的editplus）打开，拷贝代码，删除这个文件，重建一个新文件，复制刚才的代码进去，存文件的时候，一定要存成UTF-8的，上传覆盖原文件，应该就好了。
