Windows下Apache报错:通常每个套接字地址(协议/网络地址/端口)只允许使用一次

刚才sanp在windows平台下配置apache
报了如下一个错误:

(OS 10048)通常每个套接字地址(协议/网络地址/端口)只允许使用一次。 : make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down

导致这个问题的原因如下:

1: 可能是本机同时安装了IIS,占用了80端口,关闭IIS重启Apache
2: 可能是本机开着迅雷或者其他软件占用了80端口,试着关闭相关软件

sanp是因为本机开着迅雷导致这个问题, 关闭了就正常了.

XCHM中文乱码如何解决?

我的xchm打开chm文件时

中文内容是可以显示的

但是目录列表里如果有中文, 则显示乱码

网上搜索了一下. 应该是xchm中文支持不是很好.

推荐安装chmsee

ubuntu 下 sudo apt-get install chmsee 即可

这个可以完美支持中文chm.

当你遇到这个错误的时候
请检查你的php版本
这是一个php的bug

将php升级至php 5.2.9以上即可
或者sql查询不要使用pdo

用下面的方法强制使用php5即可

php正则判断中文字符

$str = “中国”;

//if (preg_match(“/^[".chr(0xa1)."-".chr(0xff)."]+$/”, $str)) { //只能在GB2312情况下使用
if (preg_match(“/^[\x7f-\xff]+$/”, $str)) { //兼容gb2312,utf-8
echo “正确输入”;
} else {
echo “错误输入”;
}

编码表

双字节字符编码范围

1. GBK (GB2312/GB18030)
\x00-\xff GBK双字节编码范围
\x20-\x7f ASCII
\xa1-\xff 中文 gb2312
\x80-\xff 中文 gbk

2. UTF-8 (Unicode)

\u4e00-\u9fa5 (中文)
\x3130-\x318F (韩文
\xAC00-\xD7A3 (韩文)
\u0800-\u4e00 (日文)

如何快速勾引蜘蛛

想更快速的勾引蜘蛛上你的站吗?
秘诀就是自动提交sitemap
经验证,精力最旺盛乃google spider.
提交一次,google蜘蛛就来一次.

$url = urlencode('http://domain.com/sitemap');

$ping_google = file_get_contents("http://www.google.com/webmasters/sitemaps/ping?sitemap=$url");

$ping_live = file_get_contents("http://webmaster.live.com/ping.aspx?siteMap=$url");

$ping_yahoo = file_get_contents("http://search.yahooapis.com/SiteExplorerService/V1/ping?sitemap=url");
?>

每天sitemap更新后自动执行即可
