针对初学PHP者的疑难问答

1.问:为什么出现“APACHE.EXE: cannot determine local host name.”?
答:
由于Windows版本的Apache默认情况下不指定ServerName,所以运行时会出错。
解决的办法是修改Apache安装目录下的conf目录下的httpd.conf:
- 搜索ServerName
- 去掉前面的#号
- 把ServerName后面的值换成你自己的设置,如localhost之类的
- 保存,重新启动Apache
2.问:PHP代码中函数前面的@是什么意思?
答:
@的作用是忽略调用该函数时产生的错误信息。

问4:为什么在WINDOWS下使用PHP4的SESSION功能老是报路径出错?
答4:
可能是PHP4.0在WINDOWS下的一个BUG。解决办法是把保存SESSION的路径设为当前路径(只有这样,才不会包错)。
方法是修改php.ini,把session.save_path的值设为./
