Whois търсачка

Автор: SandPrince

Ровейки се ин нета случайно попаднах на едно скриптче за whois търсачка. нека да обясня за какво служи въпреки че някои знаят за какво се иползва. Тя служи за проверка дали даден домейн е зает или не.Урока е много лесен и простичук и не изисква кой знае какви познания.

Имаме да създадем два документа:

1. style.css – тои отговаря за външния вид на търсачката

#main {
margin: auto;
border: 1px solid #cccccc;
width: 400px;
background: #F1F3F5;
font-family: Arial, Helvetica, sans-serif;
font-weight:bold;
font-size : 12px;
}

form {
margin-left: 100px;
border: 1px solid #cccccc;
width: 250px;
background: #E9ECEF;
font-family: Arial, Helvetica, sans-serif;
font-weight:bold;
font-size : 12px;
padding:5px;
margin-bottom:10px;
}

#result {
margin-left: 100px;
border: 1px solid #cccccc;
width: 250px;
background: #E9ECEF;
font-family: Arial, Helvetica, sans-serif;
font-weight:bold;
font-size : 12px;
padding:5px;
margin-bottom:50px;
}

.text {
border: 1px solid #cccccc;
}

input {
border: 0px solid #cccccc;
}


#caption{
font-family: Arial, Helvetica, sans-serif;
font-weight:bold;
margin:10px;
font-size : 14px;
color:#C64934;
}

#icon{
width:100px;
height:100px;
float:left;
background-image:url(icon.gif);
background-repeat: no-repeat;
background-position:center center;
}
#icon2{
width:100px;
height:100px;
float:left;
background-image:url(icon2.gif);
background-repeat: no-repeat;
background-position:center center;
}

#source{
text-align:right;
align:right;
padding-right:10px;
font-family: Arial, Helvetica, sans-serif;
font-weight:normal;
font-size : 10px;
color:#CCCCCC;
}

и докумнта който е самата търсачка – microWhois.php

<?php
function checkDomain($domain,$server,$findText){
// Open a socket connection to the whois server
$con = fsockopen($server, 43);
if (!$con) return false;

// Send the requested doman name
fputs($con, $domain."\r\n");

// Read and store the server response
$response = ' :';
while(!feof($con)) {
$response .= fgets($con,128);
}

// Close the connection
fclose($con);

// Check the response stream whether the domain is available
if (strpos($response, $findText)){
return true;
}
else {
return false;
}
}

function showDomainResult($domain,$server,$findText){
if (checkDomain($domain,$server,$findText)){
echo "<tr><td>$domain</td><td>AVAILABLE</td></tr>";
}
else echo "<tr><td>$domain</td><td>TAKEN</td></tr>";
}
?>
