Re: [Freeswitch-users] ESL, phpmod

17 Jun 2010

      Hi Samuel,

unfortunately I haven't, yet. I found that the "new_ESLconnection
function doesn't like a php resource as  parameter like a socket, but
rather a file descriptor like a numeric pointer. Unfortunately I have no
idea how to convert a socket to such a file descriptor in php. Maybe
there is a function in the socket object but I don't think so.

So far as we didn't solve this problem here, I using my own php
functions to read and write from/to incomming connections from
freeswitch like this:

function fs_send($csock, $cmd)
{
        if (strlen($cmd) < 1) {
                acd_log(LOG_ERR, "Empty command\n");
                return false;
        }
        $clen=strlen($cmd);
        if ($bytes_written = socket_write($csock, "$cmd\n\n", $clen) ===
false) {
                acd_log(LOG_ERR, "Can't send cmd! Wrote $bytes_written
bytes\n");
                socket_write($csock, "\n\n");
                return false;
        }

        return true;
}

function fs_recv($csock, &$rbuf)
{
        $i=0;
	$buf="";
        do {
                acd_log(LOG_DEBUG, "Reading from socket '$csock'.\n");
                if (($tbuf = socket_read($csock, 10000)) === false) {
                        acd_log(LOG_ERR, "Can't read from client socket!
(".socket_last_error($csock)."/".socket_strerror(socket_last_error($csock)).")\n");
                        return false;
                }
                acd_log(LOG_DEBUG, "Read ".strlen($tbuf)." bytes from
socket '$csock'.\n");

                $buf .= $tbuf;
                $i++;
        } while (substr($buf, -2) != "\n\n" and $i <10);

        foreach (explode("\n", $buf) as $t) {
                list($key, $val) = explode(": ", $t);
                $rbuf[strtolower($key)]=$val;
        }

        return true;
}

acd_log() is just my own logging functions. you can replace it with
echo() or so.

You can build on this functions more abstract functions like
fs_connect(), fs_sendRecv(), ...

The command format is as described on FS wiki
(http://wiki.freeswitch.org/wiki/Event_socket_outbound)

That works quite good, but using the phpmod for esl would be more easy..

Hi Helmut,
I got the same error:
"No matching function for overloaded 'new_ESLconnection' in
/usr/share/php/ESL.php"
Have you solved the problem?
Thanks,

Hi Michael,
ESL is built and installed, phpmod is built and installed.
inbound works, test scripts works
It is just the problem of passing an existing socket to new ESLconnection.
A socket resource is denied, an integer is accepted but is rejected with
"bad file descriptor"

Make sure the ESL is properly built and that the PHP mod is built and
installed. If you did a "make current" recently the you'll need to rebuild
your ESL stuff.

Hello,
I try to setup a php daemon which uses ESL.
I run the sample php scripts successfully (inbound). Now I want to have
it outbound to my php daemon socket.
The forked child process which has to interact with incoming tcp
connection from FS is started successfully. So in this state I have the
client socket which I have to pass now somehow to ESLconnection I guess.
FS ruby wiki gives this as an example:
@con = ESL::ESLconnection.new(client_socket.fileno)
In php I try this:
$con = new ESLconnection($csock);
As a result I got this error:
PHP Fatal error:  No matching function for overloaded
'new_ESLconnection' in /usr/share/pear/ESL.php on line 117
Any ideas?

Helmut
