write response to browser window

[panini]

hi again,

I'm a php newbie - and am having a problem with the code below.

Basically it's timing out or cutting the request off before it gets a response back from the remote server (which can take up to 10 seconds). I'd also like to write the server response to the screen - can anyone point me in the right direction?

The code is:

<?php
$fp = fsockopen ("192.168.1.24",6100,$errno, $errstr);
if (!$fp)
{
print "Unable to Connect";
}
fputs($fp,"-mc6 -tr0 -ds1\"MAIL\" -rfC -x"); //send data
$ready = fgets($fp, 3);

for ($elapsed = 0; $elapsed < 256; $elapsed++)
{
$script_result = 5;
$tcp_response = fgets($fp,1);
$z = strpos($in_data, "-x");
if ($z != 0) // -x found
{
$elapsed = 256;
$in_data = sprintf("%s%s",$in_data,$tcp_response);
fputs($fp,"ACK\n");
}
else
{
$in_data = sprintf("%s%s",$in_data,$tcp_response);
}
}



fclose($fp);

?>

I would set in intermediate print statements so that you can better understand how far the script is getting:

<?php
$fp = fsockopen ("192.168.1.24",6100,$errno, $errstr);
if (!$fp)
{
    print "Unable to Connect";
}
[COLOR=red]print "Supposed connection....sending data";[/color]
fputs($fp,"-mc6 -tr0 -ds1\"MAIL\" -rfC -x"); //send data
[COLOR=red]print "Data sent. getting..."; [/color]
$ready = fgets($fp, 3);
[COLOR=red]print "initiating 256 gets...";[/color]
for ($elapsed = 0; $elapsed < 256; $elapsed++)   
{
    $script_result = 5;
    $tcp_response = fgets($fp,1);
    $z = strpos($in_data, "-x");
    if ($z != 0) // -x found
    {
    $elapsed = 256;
    $in_data = sprintf("%s%s",$in_data,$tcp_response);
    fputs($fp,"ACK\n");
    }
    else
    {
    $in_data = sprintf("%s%s",$in_data,$tcp_response);
        }
}



fclose($fp);

?>

put in oogles of them so that you will know exactly where the script is hanging....

The other thing that I would check is to see if the remote machine is accepting the connection. Not sure I know how you would check that. Depending on the program you have running over there (if its your program, and you have physical access to the machine) make it print something to the screen everytime something connects.
