a small code with socket for domains name!!!

[kdman]

i make a code to post something in php socket and get the results, but i can't to do it like what i need

my code is to test if the domain is avilabel or not :

<?php
 $socket = fsockopen("whois.afilias.net", 43);
  if(!$socket)
  {
    echo "No Socket<BR>\n";
  }
  else
  {
    fputs($socket,"webhosting.info\r\n");
    while(!feof($socket))
    {
      $results .= fgets($socket,128);
    }
    fclose($socket);
  }
   echo $results;
?>

my problem is i cant put the veriables what i want, i need to make something like this form but in socket :

<form action="http://www.sitename.com/path/folder/search.php">
<input type="text" name="kayword">
<input type="hidden" name="lang" value="en">
<input type="submit" value="search">
</form>

any one know how to put more than one veriable and send it to some page ?
or just tell me to some script like that, thanks.

This might be useful to you. (Some of the newline characters don't have backslashes, so you'll need to add them.)

[kdman]

thank you very much senior Installer
that what i was want it exactlly 🙂

i added the backslashes for n, but i got a small problem :
every site i tried a post on it, i got : Error 13 Permission denied 🙁

anyway thank you agine for your help

[kdman]

ok, i have a small code now :

<?
    $Host = "www.google.com";
    $URI = "/search";
    $v = "al=en&q=test";
//  Generate the request header
    $ReqHeader =
      "POST $URI HTTP/1.1\n".
      "Host: $Host\n".
      "User-Agent: testSearching\n".
      "Content-Type: application/x-www-form-urlencoded\n".
      "Content-Length: 12\n".
      "$v\n";

//  Open the connection to the host
    $socket = fsockopen($Host, 80, &$errno, &$errstr);
    if (!$socket) {
      $Result["errno"] = $errno;
      $Result["errstr"] = $errstr;
      }
    $idx = 0;
    fputs($socket, $ReqHeader);
    while (!feof($socket)) {
      $Result[$idx++] = fgets($socket, 128);
    }

  if (isset($Result["errno"])) {
    $errno = $Result["errno"]; $errstr = $Result["errstr"];
    echo "<B>Error $errno</B> $errstr";
    exit;
  }
  else {
    while (list($key, $val) = each($Result)) echo $val;
  }
?>

anybody know what's the wrong with this code ??? i don't got any respond when i execut it :queasy:

You're missing the blank line between the headers (everything up to the "Content Length") and the content ($v).

Does Google take its queries via POST as well as GET? Or did you just do that for the sake of example?

[Installer]

Here's a script that works for me:

function post($data_arr, $url, &$err_no, &$err_str)
{ 
    if (substr($url, 0, 7) != 'http://') {
        $url = 'http://' . $url;
    }
    $parse_url = parse_url($url);

echo '<b>$parse_url:</b><br />';
foreach ($parse_url as $key => $value) {
    echo '&nbsp;&nbsp;' . $key . ' => ' . $value . '<br />';
}
echo '<br />';

$post_str  = ''; 
foreach ($data_arr as $key => $value) {
    if ($post_str) {
        $post_str .= '&';
    }
    $post_str .= $key . '=' . urlencode($value); 
}

echo '<b>$post_str:</b> ' . $post_str . '<br />';
echo '<br />';

$url  = str_replace('http://', '', $url);

echo '<b>$url:</b> ' . $url . '<br />';
echo '<br />';

$host = substr($url, 0, strpos($url, '/'));

echo '<b>$host:</b> ' . $host . '<br />';
echo '<br />';

$uri  = strstr($url, '/');

echo '<b>$uri:</b> ' . $uri . '<br />';
echo '<br />';

$hdr['POST']            = $parse_url['path'] . ' HTTP/1.0';
$hdr['Accept']          = 'application/x-www-form-urlencoded';
$hdr['Referer']         = 'http://' . $_SERVER['SERVER_NAME'] . 
                          $_SERVER['PHP_SELF'];
$hdr['Accept-Language'] = 'en-us';
$hdr['Content-Type']    = 'application/x-www-form-urlencoded';
$hdr['Accept-Encoding'] = 'gzip, deflate';
$hdr['User-Agent']      = 'Mozilla/4.0 (compatible; MSIE 6.0; ' .
                          'Windows NT 5.1; SV1; .NET CLR 1.1.4322)';
$hdr['Host']            = $parse_url['host'];
$hdr['Content-Length']  = strlen($post_str);
$hdr['Connection']      = 'Keep-Alive';
$hdr['Cache-Control']   = 'no-cache';
$header = '';
foreach ($hdr as $key => $value) {
    if ($key == 'POST') {
        $header .= $key . ' '  . $value . "\r\n";
    } else {
        $header .= $key . ': ' . $value . "\r\n";
    }
}
$request = $header . "\r\n" . $post_str;

echo '<b>$request:</b><br />';
echo nl2br($request) . '<br />';
echo '<br />';

$socket = fsockopen($host, 80, $err_no, $err_str, 20); 
if (!$socket) { 
    $err_no  = $result['errno']; 
    $err_str = $result['errstr']; 

    echo '<font color="red"><b>fsockopen() failed.</b></font><br />';
    echo '<br />';

    return false; 
}

echo '<font color="green"><b>fsockopen() succeeded.</b></font><br />';
echo '<br />';

$idx = 0; 
$fwrite = fwrite($socket, $request);

if ($fwrite == false) {
    echo '<font color="red"><b>fwrite() failed.</b></font><br />';
} else {
    echo '<font color="green"><b>fwrite() succeeded.</b></font><br />';
}
echo '<br />';


while (!feof($socket)) { 
    $response[] = fgets($socket, 128); 
} 
return $response; 
}

All the "echo" statements are for testing/debugging only, of course. Also, some elements of the "$hdr" array can be changed or removed.

Here's some code for testing:

$data = array('test' => 'data', 'submit' => 'submit');
$url  = 'http://www.example.com/';
$post_result = post($data, $url, $err_no, $err_str);
if ($post_result === false) {
    echo '<font color="red"><b>Error # ' . 
         $err_no . ': ' . $err_str . '</b></font>';
} else {
    echo '<b>$response: </b>' . '<br />';
    foreach ($post_result as $value) {
        echo nl2br($value);
    }
}

yesssssssssssssss
you did it Installer 🆒

thank you very much, finally i can open a socket succesfully 🙂

i tried it and it's work ok , but on some site the page still opening and the veriables send many times, and at the end i got : page can't be display , or time out.

i'll try to something by myself but the imprtant thing now that the socket had been opened successfully 😉

and thank you Weedpacket for your help .

[Installer]

I'm glad you're having some success. 🙂

Looking at it again, I see I made a coding error (doesn't affect functionality). These lines:

$err_no  = $result['errno'];  

$err_str = $result['errstr'];  

should be deleted altogether. They actually overwrite the error information.

Also, I'd change the "if ($fwrite == false)" block to:

    if ($fwrite == false) { 

    echo '<font color="red"><b>fwrite() failed.</b></font><br />';
    echo '<br />'; 

    $errno = 'xvii';
    $err_str = 'fwrite() error';
    return false;

} else { 
    echo '<font color="green"><b>fwrite() succeeded.</b></font><br />'; 
    echo '<br />'; 
}

That might give you some clue when it doesn't work right.

[kdman]

thank you for edit.

this is the most hard thing to understand in PHP as what i saw.

i did the edits but the same result (noresponding on some site's, but the veriable had been sent) 🙁

i just want to know why the code work ok on this link :
http://www.holotech.net/formdump.php

and got no responding on this :
http://post.smsdriver.com/smshurricane3.0.asp

i just want to send an SMS via Post because they don't accept the GET method 🙁

i recive the SMS but i want to see the result of sending like any other site.

[Installer]

The second server you listed accepts your post, and the sms message in your post successfully received by the end-recipient, but you get nothing back from the server, not even a response header. Is that correct?

I'm afraid I don't know what to suggest, other than contacting the server owner. It may have to so with it being an asp server, or that certain request headers need to be sent, or another reason. Maybe someone else on the forum knows more about it (although I think this is beyond a PHP question now). Or you may be able to find another forum dedicated to the subject. A couple I found:
Here and here

hth

[kdman]

hmmmm
anyway thank you very musch for your help, and i'll try agine and agine :rolleyes:

[kdman]

finally fix it 😃

for more info if anybody have a same problem in socket, he can just read PHP Manual function and he'll find this :

feof
(PHP 3, PHP 4 , PHP 5)

feof -- Tests for end-of-file on a file pointer
Description
bool feof ( resource handle )

Returns TRUE if the file pointer is at EOF or an error occurs (including socket timeout); otherwise returns FALSE.

Warning

If a connection opened by fsockopen() wasn't closed by the server, feof() will wait until a timeout has been reached to return TRUE. The default timeout value is 60 seconds. You may use stream_set_timeout() to change this value.

[Installer]

So what was the problem? 60 seconds wasn't long enough for the server to reply? That's a long time. Or that your script execution time wasn't long enough?

[kdman]

feof function well not got the end of file while the conection didn't closed from the remot server, so it'll wait the time out (60 second).

i just removed feof function and get the data manual like this :

      for ($i=0;$i<18;$i++) {
            $response[$i] = fgets($socket, 100);
      }

i know this can't be usefull for all site's to get the data, but this exactlly what i need for this site no more.
