socket read and write in the same time

[alin19]

i have a server to what i connect, and that server sends me data almost all the time,

 

and i have to send some data to it also, so i have developed this code.

 

but my connect program waits for some date to come and after that send's it so if there for some time i don't recive any dates it won't send any, just waiting to read ....

 

can you help me?

 

<?php

$sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_connect($sock,"127.0.0.1", 9191);
socket_set_block($sock);
if (false === ($line = socket_read($sock, 2048))) 
            echo "socket_read() failed: reason: " . socket_strerror(socket_last_error($msgsock)) . "\n";
else
	echo $line."\r\n";

if (false === ($line = socket_read($sock, 2048))) 
            echo "socket_read() failed: reason: " . socket_strerror(socket_last_error($msgsock)) . "\n";
else
	echo $line."\r\n";

$user=toUTF("user");
socket_write($sock, $user);


if (false === ($line = socket_read($sock, 2048))) 
            echo "socket_read() failed: reason: " . socket_strerror(socket_last_error($msgsock)) . "\n";
else
	echo $line."\r\n";

	$parola=toUTF("password");
socket_write($sock, $parola);



while (true)
{

if (false === ($line = socket_read($sock,10000))) 
            echo "socket_read() failed: reason: " . socket_strerror(socket_last_error($msgsock)) .             "\n";
           else	

			     {

				echo $line;	
				} 
	$order="test";
	$order=toUTF($trim);
	if (socket_write($sock, $order)) 
}

function toUTF( $content ) {
$contentLen  = strlen( $content );
$newContent  = pack( "n", $contentLen );
$newContent .= $content;


    for ( $i = 0; $i < strlen( $newContent ); $i++ ) {
        print ord( substr( $newContent, $i, 1 ) )." ";
    }
    print "\n";


return $newContent;
}
