[求助!]改端口难!

一般都是修改apache的端口，你为什么要修改mysql的端口号呢？确认my.php中的mysql端口号要改好。

通过那个蓝色的控制程序，将php.ini文件切换到development状态，看看有啥错误输出。

应用环境多种多样.改端口应该是很常见的吧.

php.ini 切换为 development后,访问页面出现:

解决了,
参考:http://www.91php.cn/rewrite.php/read-188.html
真正问题核心如下:

--------------------------------------------------------------------------------------
如果使用utf-8编码，一定要去掉UTF-8中的BOM，这都是因为utf-8编码文件含有的bom原因，而php4,5都是不支持bom的。去掉bom，可以用Notepad++打开转换一下。切记，切记，切记！（这问题害我折腾了半天。）
--------------------------------------------------------------------------------------

cmd下用 edit F:zentaohomezentaoconfigmy.php 把开头的BOM去了就成了。

这是个老问题了,windows下开发几乎每年都能遇到1、2回（经常被同事问），没想到又载这上面了...（PHP不熟悉，没想到到一样也有这问题）

感谢wwccss，赫赫。先用去了，回头有问题再麻烦你，哈哈。

hehehe。
