(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);

}
