php session_start()关于Cannot send session cache limiter

cache headers limiter php session start about

说是已经有输出,用编辑器打,前面明明什么都没有,原来在使用AJAX的 时候,也出现过这种情况,后来,把这个PHP文件放到linux中打开,会发现,在文件的最前面,会出现“锘 ”这样的一个字符(引号内),把它去掉以后,再运行,OK,运行正常。后来在网上搜索一些文件,给的解释是:UTF8文件的BOM(Byte Order Mark)标志,在保存的时候会自动存入!
不管它是干嘛的,现在的目的就是把它去掉,我总结的方法有下面三种:
1、 在Linux下打开,去掉后再保存
2、 用写字板打开,把光标放到最前后回车,然后再敲删除,重新回到第一行,这样最前面的那个字符就会去掉
3、 使用UltraEdit编辑器(很好用的一个编辑器,网上多的是,自己下去),打开高级----配置----Unicode/utf-8 检测,把自动检测UTF-8文件,自动检测没有BOM的Unicode文件等前面的勾全去掉,然后你再打开那个文件,就会发觉“锘 ”这个字符出现了,删除就OK了


笨方法:难道有很多页面的时候,你也这样做吗?
在PHP页面首部直接设置OB_START();,就可以解决!

解决办法:
修改php.ini中的session.auto_start = 0 为 session.auto_start = 1
output_buffering =改为on或者任何数字。
然后别忘记重新启动...
