Edit line values problem in PHP

[ChrisMartino]

Well i have a function to edit find the value in a file using SSH2 and PHP, Here's what i have:

 

My problem is that it won't edit the values for some reason, I've checked and all the directory's that it is fetching are correct but no file editing takes place?.

public function CheckClientConfig($serverid)
	{
		if($this->IsValidGameServer($serverid))
		{
			$ClearID = mysql_real_escape_string($serverid);
			$ObtainDetails = mysql_query("SELECT * FROM gameservers WHERE ServerID = '".$ClearID."'");

			$Fetch = mysql_fetch_array($ObtainDetails);

			$SelectServer = mysql_query("SELECT * FROM servers WHERE ServerName = '".$Fetch[OnServer]."'");

			$FetchServer = mysql_fetch_array($SelectServer);

			$SelectPackage = mysql_query("SELECT * FROM serverpackages WHERE PackageNAME = '".$Fetch[Game]."'");

			$PackageRow = mysql_fetch_array($SelectPackage);

			$ssh = new Net_SSH2($FetchServer['IP']);

     			if (!$ssh->login($FetchServer['RootUsername'], $FetchServer['RootPassword'])) 
			{
         			exit('There was a error Re-Starting the server, Please re-try or contact support.');
     			}		

			$ReadConfig = $ssh->exec("sudo -u root cat /home{$Fetch['Directory']}/{$PackageRow['ConfigFile']}");
			        
			$config_file = explode("\n",trim(str_replace("\r",'',$ReadConfig)));
			$config_done = array();
			$config = '';

			foreach($config_file as $key => $line)
			{
				$line = trim($line);
				$ex = explode(' ',$line);
				if(strlen($ex[0]) != 0)
				{
					if(isset($ex[1])) $config_done[strtolower($ex[0])] = (string)$ex[1];
					else $config_done[strtolower($ex[0])] = true;
					if(strcasecmp($ex[0],'maxplayers') == 0)
					{
						$slots = (int) $ex[1];
						if($slots > $Fetch['Slots'] or $slots == 0)
						{
							$config .= 'maxplayers '.$Fetch['Slots']."\n";
						}
						else
						{
							$config .= 'maxplayers '.$slots."\n";
						}
					}
					elseif(strcasecmp($ex[0],'port') == 0)
					{
						$config .= 'port '.$Fetch['Port']."\n";
					}
					else
					{
						$config .= $line."\n";
					}
				}
			}

			if(!isset($config_done['maxplayers'])) $config .= 'maxplayers '.$Fetch['Slots']."\n";
			elseif($config_done['maxplayers'] === true) $config .= 'maxplayers '.$Fetch['Slots']."\n";

			$ssh->exec("echo '/home{$Fetch[Directory]}/{$PackageRow[ConfigFile]}' > ".$config);

		}
	}

you should use echo like this

echo 'string' > /path/to/file

 

for example

	

$ssh->exec("echo '$config' > /home{$Fetch[Directory]}/{$PackageRow[ConfigFile]}");

 

Also, the code posted in your linux thread should work fine

This way still doesn't seem to work though? :[

You might want to read up on debugging. Here is a nice article that I used when I first started - http://www.ibm.com/developerworks/library/os-debug/ . It is a bit old(2005) but the basic concepts still apply.
