I'm writing a proxy server in PHP. The proxy server works and is able to render HTML, but JavaScript code will not work. Based on research I've done, many other proxy servers also have problems with JavaScript.
Here is the code I'm using.
#set_time_limit(60);
$fp = fsockopen(".$page.", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$out = "GET / HTTP/1.1\r\n";
$out .= "Host: ".$hostname."\r\n";
$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
$x=0;
while (!feof($fp)) {
echo fgets($fp, 128);
fclose($fp);
}
}
Help would be greatly appreciated.

Hi I'm trying to write a client-server function. I've written part of the code from the client side asking the server to login, I now need some simple code to start me off that I could use as a response from the server.
Client code:
<?php
$fp = fsockopen("XXXX.XXXXX.com", 1980, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$out = "<UserStatus timestamp='0' type='login' UserID='####' key='XXXX' /> \r\n";
fwrite($fp, $out);
while (!feof($fp)) {
echo fgets($fp, 128);
}
fclose($fp);
}
?>
Please can some give me an example of some code.
I am trying to post parameters from php to another server. When creating the link manually and opening it in the browser it works fine. But when trying to do it from my php-script it doesn't work. The file I am accessing is accessed, but the parameter is not posted.
I guess the problem has to do with how I define and post the parameter ($post_data .= "?companyid=banane";). What is my problem and how do I solve it?
<?php
$fp = fsockopen("192.168.1.102", 80, $errno, $errstr, 30);
error_log("write done");
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$post_data = "GET /cgi-bin/new_instance.pl HTTP/1.1\r\n";
$post_data .= "Host: 192.168.1.102\r\n";
$post_data .= "Connection: Close\r\n\r\n";
$post_data .= "?companyid=banane";
error_log("OUT - - - ".$post_data);
fwrite($fp, $post_data);
error_log("write done");
while (!feof($fp)) {
echo fgets($fp, 128);
}
fclose($fp);
}
?>
Or am I using the wrong approach? I'm thinking, if this is the correct approach then I should be able to find some good examples when googling around.
Try this as the first line instead:
GET /cgi-bin/new_instance.pl?companyid=banane HTTP/1.1\r\n
i need to telnet to a port and send command and write the output into a txt file using PHP.How i do it?
in this forum have a same question name telnet connection using PHP but their have a solution link and the solution link is not open so i have to make the question again.
Also i try the code below from php site but it does not save the proper output into a text file.Code:
<?php
$fp = fsockopen("localhost", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$out = "GET / HTTP/1.1\r\n";
$out .= "Host: localhost\r\n";
$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
while (!feof($fp)) {
echo fgets($fp, 128);
}
fclose($fp);
}
?>
So,please help me to solve the problem.How i telnet to localhost port 80 and send command GET / HTTP/1.1 and write the output into a text file?
With a simple additition, your example script can write the output to a file, of course:
<?php
$fp = fsockopen("localhost", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$out = "GET / HTTP/1.1\r\n";
$out .= "Host: localhost\r\n";
$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
$output = '';
while (!feof($fp)) {
$output .= fgets($fp, 128);
}
fclose($fp);
file_put_contents( 'output.txt', $output );
}
Then again, I agree with Eduard7; it's easier not to do the request manually and just let PHP solve it for you:
<?php
// This is much easier, I imagine?
file_put_contents( 'output.txt', file_get_contents( 'http://localhost' ) );
You really want to do this with telnet? What about:
echo file_get_contents("http://127.0.0.1:80");
Or if You want to customize the request, you can use cURL - http://php.net/manual/en/book.curl.php
How to open TCP connection in PHP and send some String over that connection ( for example "test") ?
You can create a socket with socket_create, open it with socket_connect and write with socket_write. socket_write documentation on php.net
You can try the example from this link:
<?php
$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$out = "GET / HTTP/1.1\r\n";
$out .= "Host: www.example.com\r\n";
$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
while (!feof($fp)) {
echo fgets($fp, 128);
}
fclose($fp);
}
?>
