Help with commas in RealChat rooms string

[Boofo]

Could anyone please help me add commas to the string of RealChat rooms that the following code generates?

PHP Code:

// REALCHAT WHO'S ONLINE
$port = 10010;
function getServerAPI( $apiCommand ) {
global $port;
$result = "";
$fp = fsockopen("localhost", $port, &$errno, &$errstr, 2);
if(!$fp) {
echo "$errstr ($errno)\n";
} else {
fputs($fp,"GET /?".$apiCommand." HTTP/1.0\n\n");
$header = true;
while(!feof($fp)) {
$line = fgets($fp,128);
if ( $header == false ) $result .= $line;
if ( trim($line) == "" ) $header = false;
}
fclose($fp);
}
return $result;
}
$userCount = getServerAPI( "api.UserCount" );
$roomList = getServerAPI( "api.RoomList" );
// End REALCHAT WHO'S ONLINE 


Right now it looks like this:

Available RealChat Rooms: The Bear's Den The Lobby Fun Staff only! No topic Bear's Den

The rooms are:

The Bear's Den
The Lobby
Fun
Staff only!
No topic
Bear's Den

I would like commas after the names except for the last one.

This is the code that came with it so I have no idea how to add the commas.

Thanks in advance.

Assuming that each channel is being retrieved on its own line, you should be able to:

PHP Code:

function getServerAPI($apiCommand)
{
    global $port;
    
    $result = "";
    
    $fp = fsockopen("localhost", $port, &$errno, &$errstr, 2);
    
    if(!$fp)
    {
        echo "$errstr ($errno)\n";
    }
    else 
    {
        fputs($fp,"GET /?".$apiCommand." HTTP/1.0\n\n");
        
        $header = true;

        while(!feof($fp))
        {
            $line = fgets($fp,128);
            
            // print $line;

            if ($header == false)
                $result .= $line . ', ';

            if (trim($line) == "")
                $header = false;
        }

        fclose($fp);
    }
    
    return substr($result, 0, -2); // trim the last ', '
} 


To get the comma separated list. If it's not separated by a line, uncomment the echo I have in the loop and check the output.

Ok that almost works. We have an extra space between the room name and the commas, though. Like this:

Available RealChat Rooms: The Bear's Den , The Lobby , Fun , Staff only! , No topic

How do I take the extra space out of that?

And thank you, very much, sir.

Replace:

PHP Code:

$result .= $line . ', '; 


With:

PHP Code:

$result .= substr($line, 0, -1) . ', '; 


Should do it.

Excellent! Worked like a charm! Thank you, sir.

you could also use the php trim() function. It removes all surrounding whitespace characters, which is very helpful when dealing with strings.

How would you incorporate that into this?

[Velocd]

Instead of doing:

PHP Code:

$result .= substr($line, 0, -1) . ', '; 


Use:

PHP Code:

$result .= trim($line) . ', '; 


Probably isn't any faster, but it's more appropriate.

Thank you, again, sir.

For future reference, will the trim get rid of whitespace on both sides of the line or just the preceding whitespace?

I am getting a comma after the amount of users in the chat room randonly now. It doesn't happen all the time but every once in a while. Like this:

RealChat Users Connected: 0,

Is there any way to prevent this?
