On my webserver I run a VoIP sever (Ventrilo) and there is a status program that comes with it. I am very new to PHP but am wanting to create a block that will parse the few lines of text that comes out and tell if the server is up (its up if there is text) and how many users are online.
Is there anyone out there who could provide me some direction on how to do this? Thanks.

The command ./ventrilo_status -c2 -t127.0.0.1 returns the following

and when you GREP it ( ./ventrilo_status -c2 -t127.0.0.1 | grep 'CLIENTCOUNT')

try this type of idea--for your lib-custom.php if you create a php block:
function phpblock_voipOutput(){
global $command_output;
if(empty($command_output)){
$retval = '';
} else {
$pos = strpos($command_output,'CLIENTCOUNT') + 14;//accounts for ': '
$clients = substr($command_output, $pos);
$retval = '<p>Clients online: ' . $clients . '</p>';
}
return $retval;
}
I don't know ventrilo so I cant be accurate at all. And I'm not sure how you'll pass your output to the function, but once it's there, something along these lines should help.
just off the top of my head

yes... substr() in the above code will take everything from "clientcount" to the end of the string. If the client count is at the end of the string then all is well, if another piece of data comes after then we have a problem. So we would add a check somehow to create a third parm for substr() telling it where to stop. Perhaps the check would find the position any character not an integer that comes after our count and let that position-1 be substr()'s third parm.
make sense?

Here is the code I have right now
global $command_output;
$command_output = system("./ventrilo/ventrilo_status -c2 -t127.0.0.1 | grep 'CLIENTCOUNT'");
if(empty($command_output)){
$retval = '';
} else {
$pos = strpos($command_output,'CLIENTCOUNT') + 14;//accounts for ': ';
$clients = substr($command_output, $pos);
$retval = '<p>Clients online: ' . $clients . '</p>';
}
return $retval;
}
I have no idea if i have the syntax on the system correct. I never did get how to use ' or "
The ventrilo_status program will only run when it is then folder. How do I make sure the path is correct. The command I have there will run the program as if i were in my home dir.

you wont need the "global" line.
and the quickest way to test a path is right or not is to test the script.
have you run it yet? did it work? any errors?

is the system command correct?
here is the block as i have it in lib-custom.php
function phpblock_voipoutput() {
// global $command_output;
$command_output = system("/home/tupper/ventrilo/ventrilo_status -c2 -t127.0.0.1 | grep 'CLIENTCOUNT'");
if(empty($command_output)) {
$retval = 'NOT ON';
} else {
$pos = strpos($command_output,'CLIENTCOUNT') + 14;//accounts for ':
$clients = substr($command_output, $pos);
$retval = '<p>Clients online: ' . $clients . '</p>';
}
return $retval;

as I said earlier, I don't know the voip software and so the command itself is up to you. But let me make a quick change or two:
//Ventrilo Status
function phpblock_voipoutput() {
//system() only returns last line
$last_line = system("/home/tupper/ventrilo/ventrilo_status -c2 -t127.0.0.1 | grep 'CLIENTCOUNT'", $count);
if(empty($count)) {
$retval = '<p>NOT ON</p>';
} else {
$retval = '<p>Clients online: ' . $count . '</p>';
}
return $retval;
}
adding the 2nd parm to system loads its output into that variable. and because your command uses grep for the clientcount, all the string pos stuff is unnecessary.

It will now spit out Client online but even if there are 2 or more people on it still only says 1.
So obvioulsy the command to the system is working but not the stripping. Would putting the return value in an array and then stripping after the space and returning the digits work, or is that way to inefficient?

if $count doesn't contain the value then it doesn't matter what you do with it, you won't get anything else than TRUE, which it seems to be now.
my last try:
//Ventrilo Status
function phpblock_voipoutput() {
//system() only returns last line
system("/home/tupper/ventrilo/ventrilo_status -c2 -t127.0.0.1 | grep 'CLIENTCOUNT'", $count);
if(empty($count)) {
$retval = '<p>NOT ON</p>';
} else {
$retval = '<p> . $count . '</p>';
}
return $retval;
}
just a noob myself yaknow

Thanks so much for your help. I got it working and this is the final code.
function phpblock_voipoutput() {
//system() only returns last line
$status = exec('./ventrilo_status -c2 -t127.0.0.1 | grep 'CLIENTCOUNT'');
if(empty($status)) {
$retval = '<p>Server address: www.othersideofspecial.com:3784</p><p><strong><font color="#FF0000">OFFLINE</font></strong></p><p><a href="http://www.ventrilo.com">Get Ventrilo</a></p>';

I was going to suggest passthru or exec last time, but didn't want to push my luck.

use eregi_replace() to clean your string of the unwanted text.
e.g.:
$status = eregi_replace('CLIENTCOUNT: ', '', $status);

THIS BLOCK IS FINISHED 
Thank you so much for your help. That last little bit just cleaned it up nice and tidy. I had to do a little variable work cause if there is noone online empty() would return false, but it now works exactly like i want it to.
Here is the final code.
//Ventrilo Status
function phpblock_voipoutput() {
$status = exec('./ventrilo_status -c2 -t127.0.0.1 | grep \'CLIENTCOUNT\'');
// Have to put the status variable so that empty() will not return false if noone is logged on
$srvstatus = $status;
$status = eregi_replace('CLIENTCOUNT: ', '', $status);
if(empty($srvstatus)) {
$retval = '<p>Server address: www.othersideofspecial.com:3784</p><p><strong><font color="#FF0000">OFFLINE</font></strong></p><p><a href="http://www.ventrilo.com">Get Ventrilo</a></p>';
} else {
$retval = '<p>Server address: www.othersideofspecial.com:3784</p><p><strong><font color="#00FF00">ONLINE</font></strong></p><p>Clients Online : ' . $status . '</p></p><p><a href="http://www.ventrilo.com">Get Ventrilo</a></p>';
}
return $retval;
