(主要用了两个字符串函数implode()和explode)
我制作的域名查询的源代码，主要用了两个字符串函数implode()和explode，利用这两个函数的切割字符串的强大功能,可以查询.com,.net.,org.,cc.,tv下的域名whois。
<?php
echo '<center<form';
echo '<input type="text" name="string"';
echo '<input type="submit" value="查询"';  
echo "</form";
if (isset($string))  
{
$url = "http://networksolutions.com/cgi-bin/whois/whois?STRING=".$string."&STRING=Search";  
$str = implode("",file($url));        
$aa= explode("<pr",$str);      
$bb=$aa[1];
$cc=explode("re",$bb);
$dd= $cc[0];
$ee=explode("e",$dd);
$ff=implode("<pre",$ee);
$hh=explode("</p",$ff);
$jj=implode("</pre",$hh);
$kk=explode("Registrant",$jj);
$ll=implode("<font color=red注册人</font",$kk);
$mm=explode("Domain Name",$ll);
$nn=implode("<font color=red域名</font",$mm);
$oo=explode("Administrative Contact",$nn);
$pp=implode("<font color=red管理联系人</font",$oo);
$qq=explode("Technical Contact",$pp);
$ii=implode("<font color=red技术联系人</font",$qq);
$ss=explode("Record last updated on",$ii);
$tt=implode("<font color=red最后更新日期:</font",$ss);
$uu=explode("Record expires on",$tt);
$vv=implode("<font color=red域名到期日期:</font",$uu);
$ww=explode("Record created on",$vv);
$xx=implode("<font color=red域名注册日期:</font",$ww);
$yy=explode("Database last updated on",$xx);
$zz=implode("<font color=red数据库更新日期:</font",$yy);
$aaa=explode("Record updated on",$zz);
$bbb=implode("<font color=red记录更新日期:</font",$aaa);
$ccc=explode("Admin Name",$bbb);
$ddd=implode("<font color=red管理联系人</font",$ccc);
$eee=explode("Tech Name",$ddd);
$whois=implode("<font color=red技术联系人</font",$eee);
}
echo '<center<table width="50%" border="0" cellspacing="1" cellpadding="0" bgcolor="#FF6666"';
echo '<tr bgcolor="#ffcc33"';
