Hi, i found a php updater script
Code PHP:
<h1>DYNAMIC UPDATE SYSTEM</h1>
<?
ini_set('max_execution_time',60);
//Check For An Update
$getVersions = file_get_contents('cmstest/current-release-versions.php') or die ('ERROR');
if ($getVersions != '')
{
	echo '<p>CURRENT VERSION: '.get_siteInfo('CMS-Version').'</p>';
	echo '<p>Reading Current Releases List</p>';
	$versionList = explode("\n", $getVersions);	
	foreach ($versionList as $aV)
	{
		if ( $aV > get_siteInfo('CMS-Version')) {
			echo '<p>New Update Found: v'.$aV.'</p>';
			$found = true;
 
			//Download The File If We Do Not Have It
			if ( !is_file(  $_ENV['site']['files']['includes-dir'].'/UPDATES/MMD-CMS-'.$aV.'.zip' )) {
				echo '<p>Downloading New Update</p>';
				$newUpdate = file_get_contents('cmstest/MMD-CMS-'.$aV.'.zip');
				if ( !is_dir( $_ENV['site']['files']['includes-dir'].'/UPDATES/' ) ) mkdir ( $_ENV['site']['files']['includes-dir'].'/UPDATES/' );
				$dlHandler = fopen($_ENV['site']['files']['includes-dir'].'/UPDATES/MMD-CMS-'.$aV.'.zip', 'w');
				if ( !fwrite($dlHandler, $newUpdate) ) { echo '<p>Could not save new update. Operation aborted.</p>'; exit(); }
				fclose($dlHandler);
				echo '<p>Update Downloaded And Saved</p>';
			} else echo '<p>Update already downloaded.</p>';	
 
			if ($_GET['doUpdate'] == true) {
				//Open The File And Do Stuff
				$zipHandle = zip_open($_ENV['site']['files']['includes-dir'].'/UPDATES/MMD-CMS-'.$aV.'.zip');
				echo '<ul>';
				while ($aF = zip_read($zipHandle) ) 
				{
					$thisFileName = zip_entry_name($aF);
					$thisFileDir = dirname($thisFileName);
 
					//Continue if its not a file
					if ( substr($thisFileName,-1,1) == '/') continue;
 
 
					//Make the directory if we need to...
					if ( !is_dir ( $_ENV['site']['files']['server-root'].'/'.$thisFileDir ) )
					{
						 mkdir ( $_ENV['site']['files']['server-root'].'/'.$thisFileDir );
						 echo '<li>Created Directory '.$thisFileDir.'</li>';
					}
 
					//Overwrite the file
					if ( !is_dir($_ENV['site']['files']['server-root'].'/'.$thisFileName) ) {
						echo '<li>'.$thisFileName.'...........';
						$contents = zip_entry_read($aF, zip_entry_filesize($aF));
						$contents = str_replace("\r\n", "\n", $contents);
						$updateThis = '';
 
						//If we need to run commands, then do it.
						if ( $thisFileName == 'upgrade.php' )
						{
							$upgradeExec = fopen ('upgrade.php','w');
							fwrite($upgradeExec, $contents);
							fclose($upgradeExec);
							include ('upgrade.php');
							unlink('upgrade.php');
							echo' EXECUTED</li>';
						}
						else
						{
							$updateThis = fopen($_ENV['site']['files']['server-root'].'/'.$thisFileName, 'w');
							fwrite($updateThis, $contents);
							fclose($updateThis);
							unset($contents);
							echo' UPDATED</li>';
						}
					}
				}
				echo '</ul>';
				$updated = TRUE;
			}
			else echo '<p>Update ready. <a href="?doUpdate=true">&raquo; Install Now?</a></p>';
			break;
		}
	}
 
	if ($updated == true)
	{
		set_setting('site','CMS',$aV);
		echo '<p class="success">&raquo; CMS Updated to v'.$aV.'</p>';
	}
	else if ($found != true) echo '<p>&raquo; No update is available.</p>';
 
 
}
else echo '<p>Could not find latest realeases.</p>';

where it says
Code PHP:
echo '<p>CURRENT VERSION: '.get_siteInfo('CMS-Version').'</p>';
how would i get the site info in another file to this one?

BTW the reason the files arn't on a website is because im developing through files
