php 遍历目录以及子目录

源码如下： 
<?php 
$dir = "c:/wamp/www/test/";  //目录名称必须是这种格式
$space="";
function fun1($dir,$space="") {
    if(is_dir($dir) && $handle = opendir($dir)){
        $space .= "&nbsp;&nbsp;&nbsp;&nbsp;";
        while(false!== ($file = readdir($handle))){
            if($file=="." || $file=="..") continue;
            if(is_dir($dir.$file.'/')){
                echo "$space|-$file<br>";
                fun1($dir.$file.'/',$space);
            }else
            echo "$space|-$file<br>";
        }
        closedir($handle);
    }else{
        echo "This have a error!";
    }
}
fun1($dir);
?>
遍历效果如下：
 |-1.php
    |-2.php
    |-2010-05-22_101859.jpg
    |-321.html
    |-ci
        |-.htaccess
        |-index.php
        |-system

本地apache虚拟主机的配置

第一步：在 C:\WINDOWS\system32\drivers\etc 下找到 hosts  文件 ，打开并且在最后加上 
127.0.0.1          localhost
127.0.0.1          uc.521-wf.com
127.0.0.1          uch.521-wf.com
第二步：在apache 的配置文件 httpd.conf 的最后加上如下的代码： 
NameVirtualHost 127.0.0.1
<VirtualHost 127.0.0.1:80>
    ServerAdmin admin@521-wf.com
    DocumentRoot c:/wamp/www/
    ServerName localhost
</VirtualHost>

<VirtualHost 127.0.0.1:80>
    ServerAdmin admin@521-wf.com
    DocumentRoot c:/wamp/www/uc/
    ServerName uc.521-wf.com
</VirtualHost>

<VirtualHost 127.0.0.1:80>
    ServerAdmin admin@521-wf.com
    DocumentRoot c:/wamp/www/uch/
    ServerName uch.521-wf.com
</VirtualHost>
但是这是核心的代码，不是固定的写法:
     ServerAdmin   你的邮件地址（不过可以随便写，这也只不过是虚拟环境而已）
      DocumentRoot  这是你项目的路径
      ServerName    这是你的虚拟域名
有时候你把上面的127.0.0.1 换为 * 也可以。但是有时候不行。我建议还是加上。
我习惯于使用 wamp  所以我并没有加在配置文件的最后面，而是加在了以下两行代码之前： 
Include "c:/wamp/apache2/conf/alias/phpmyadmin.conf"
Include "c:/wamp/apache2/conf/alias/sqlitemanager.conf"
当然如果你的操作系统装在了d盘，或者是其他盘，那就看着办吧！ 这个配置我在学校里面配置我好多次，不能说倒背如流，但是可以说是滚光烂熟了吧。但是到了公司，两个多月不用了，突然想装一下uchome ，配置了半天，老是出错 。所以 还是写在这儿，以防以后再忘了。  <<<<<<<<<<<<<<<<<<<<<<<<<<补充，还可以使用以下这种方式，更安全 
<VirtualHost *:80>
    DocumentRoot "D:/wamp/www/framework/webroot"
    ServerName star
    #ServerAlias *.shop.com.cn
    ErrorLog "logs/starland.ifensi-error.log"
    CustomLog "logs/make.openqee.com.cn.log" common  
    <Directory "D:/wamp/www/framework">
    Options FollowSymLinks
    AllowOverride All
    Order deny,allow
    allow from all
    DirectoryIndex index.html index.php
    </Directory>
</VirtualHost>

Linux whois命令寻找未注册域名

域名一直在被注册，好域名已经很少了，几乎没有了，只能高价购买了。一个程序帮助快速批量检测域名注册情况还是有必要的。 

#!/bin/sh

NO_DOMAIN_MATCH="No match for domain"
TMP_FILE="domain_tmp"

#declare -i argsnums
#argsnums= $#

if [ $# -gt 0 ]
then
        whois $1 > $TMP_FILE
        echo -e "$1 \c"
        grep -q "$NO_DOMAIN_MATCH"  $TMP_FILE && echo "is not registered!!!" || echo "is registered........"
else
        declare -a abc=(a b c d e f g h i j k l m n o p q r s t u v w x y z)
        i=1000
        j=1005

        while [ $i -lt $j ]
        do
                domain="$i.com"
                whois $domain > $TMP_FILE
                echo -e "$domain \c"
                grep -q "$NO_DOMAIN_MATCH"  $TMP_FILE && echo "is not registered!!!" || echo "is registered."
                let "i=$i+1"
        done
fi

保存以上文件为 whois.sh 然后执行 

[root@localhost ~]# sh whois.sh 521-wf.com

运行结果很友好，更加强大的功能正在加工中..........
