Please, help me to connect WebSocket with php.
I try this code, but I've got 400 Bad Request
$fp = fsockopen("cs.money", 443, $errno, $errstr, 30);
if (!$fp)
{
echo "$errstr ($errno)<br />n";
}
else
{
$out = "GET / HTTP/1.1rnrn";
///Send data
fwrite($fp, $out);
///Receive data - in small chunks :)
while (!feof($fp))
{
echo fgets($fp, 128);
}
fclose($fp);
}
I've solved my problem with js.
var WebSocket = require('ws');
var ws = new WebSocket('wss://cs.money/ws');

I want to read some phrases from an external website which protocol is https.
I've do this for websites with http protocol by this code:
$homepage = file_get_contents('https://www.examlple.com/');
echo $homepage;
but it does not work for https sites. then I used this one:
$fp = fsockopen("https://www.example.com/", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
fwrite($fp, "Data sent by socket");
$content = "";
while (!feof($fp)) { //This looped forever
$content .= fread($fp, 1024);
}
fclose($fp);
echo $content;
}
but I always get an error:
Unable to find the socket transport "http" - did you forget to enable
it when you configured PHP? (2)
actualy the case is to fetch my site's statistics from analytics.
Fsockopen does not know about "http, https". Please remove the http part from your domain and use SSL Port for connection.
See example, this should work:
// open ssl connection - dont add "http or https!"
$host = "ssl://" . "example.com";
$port = 443;
$fp = fsockopen($host,$port);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
fwrite($fp, "Data sent by socket");
$content = "";
while (!feof($fp)) { //This looped forever
$content .= fread($fp, 1024);
}
fclose($fp);
echo $content;
}
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 connect to an application for a push/stream data.
With the following code I have a right answer from the app (outcome=OK|item=THEITEM) but can't figure out how to get the var "last_value" and its updates.
The loop is commented out, I have no echo with it (loop)
$port = ('5333');
$address = ('127.0.0.1');
$fp = stream_socket_client("tcp://$address:$port", $errno, $errstr, 1);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$in = "function=subscribe|item=THEITEM|schema=last_value";
fwrite($fp, $in."\n");
//while (!feof($fp)) {
echo fgets($fp, 1024);
//}
fclose($fp);
}
This returns outcome=OK|item=THEITEM.
The updates should be like THEITEM|last_value.
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.
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);
}
?>
