R Q

Wrapper

Get the entire contents of the webpage as if it is a local file. 
 
$contents = file_get_contents('http://studyon.minte9.com');
echo $contents;

Stream context

Allows you to add extra parameters to be used with streams. 
 
$postVars = array(
    'comment' => 'Test by stream',
    'page_id' => '328',
    'page_type' => '1',
);
    //echo file_get_contents("http://studyon.minte9.com/login"); die;

$wrapperOptions = array('http' =>
    array(
        'method'  => 'POST',
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'content' => http_build_query($postVars, '', '&'),
        'timeout' => 5,
    )
);

$streamContext = stream_context_create($wrapperOptions);

echo file_get_contents("http://www.fanlafel.ro/add-comment", 0, 
        $streamContext);
    // Insert comment
You can create socket servers and clients using the stream functions. 
 
// server.php

$socket = stream_socket_server("tcp://0.0.0.0:1037");
while ($conn = stream_socket_accept($socket)){
    fwrite($conn, "Hello World");
    fclose($conn);
}
fclose($socket);

 
// client.php

$socket = stream_socket_client("tcp://0.0.0.0:1037");
if ($socket) {
    while(!feof($socket)) {
        echo fread($socket, 100);
    }
    fclose($socket);
}
Finally, we can run our server just like any other PHP script. 
 
$ php ./server.php
$ php ./client.php
Hello World
You can add a filter to the beginning and end to a stream. 
 
// server.php

$socket = stream_socket_server("tcp://0.0.0.0:1037");
while ($conn = stream_socket_accept($socket)){
    
    // add filters
    stream_filter_append($conn, '<span class='keyword_code'>string.toupper</span>');
    stream_filter_append($conn, 'zlib.deflate');
    
    fwrite($conn, "Hello World");
    fclose($conn);
}
fclose($socket);

 
// client.php

$socket = stream_socket_client("tcp://0.0.0.0:1037");

// add filter
stream_filter_append($socket, 'zlib.inflate');

if ($socket) {
    while(!feof($socket)) {
        echo fread($socket, 100);
    }
    fclose($socket);
}
