Explain me the meaning of this PHP code.

Hi,

as i m not the programmer, i need a lit bit help of yours.

please explain me the 2 piece of code below.

// Directly count file sizes
$handle = opendir ( "../files" );
$totsiz = 0;
$todaysize = 0;
while ( $filee = readdir ( $handle ) ) {
	if ($filee == '.' || $filee == '..' || is_dir($filee) || !file_exists(dirname(__FILE__)."/files/$filee")) continue;
	$timey = filemtime( dirname(__FILE__)."/files/$filee" );
	$siz = filesize ( dirname(__FILE__)."/files/$filee" );
	if (time() - $timey < 86400) {
		$todaysize += $siz;
	}
	
	$filelist [$filee] = $siz;
	$delist [$timey] = $filee;
	$totsiz = $siz + $totsiz;
}
closedir ($handle);
$origtot_size = $totsiz;
$origmax_space = $maximum_space_usage_in_mb;
$tot_size = byteConvert($totsiz);
$maximum_space_usage_in_mb = byteConvert($maximum_space_usage_in_mb);

Code (markup):

And

$REMOTE_ADDR = $_SERVER ['REMOTE_ADDR'];

$res = executeQuery('SELECT * FROM users WHERE ip="'.$REMOTE_ADDR.'"');
if ($res->numRows() == 0) {
	$res = executeQuery('INSERT INTO users (`ip`,`downloads`,`vip`) VALUES ("'.$REMOTE_ADDR.'",0,0)');
	$res = executeQuery('SELECT * FROM users WHERE ip="'.$REMOTE_ADDR.'"');
}
$row = $res->fetchRow();
if ($row['vip'] == 1) $vip = 1;
//$res =executeQuery('SELECT * FROM files WHERE ip="'.$REMOTE_ADDR.'"');
//$heute = $res->numRows();
$res = executeQuery('DELETE FROM downloads WHERE time<'.(time()-3600));
$res = executeQuery('SELECT * FROM downloads WHERE ip="'.$REMOTE_ADDR.'"');
$heute = $res->numRows();

Code (markup):

I want to increase the time how can i do that.

 

First code snippet calculates size of files in a directory.
Second one checks last 1 hour user downloads and sets whether user is vip or not.

Seems like a file hosting script code snippet..

 

Ok from what mastermunj just said and what you have said i gather you want to increase the time that is current 24 hours which would be this part here

if (time() - $timey < 86400) {
		$todaysize += $siz;
                                        }

Code (markup):

86400 is the amount of seconds in a day so if you want to increase the time i suggest you increase this

$res = executeQuery('DELETE FROM downloads WHERE time<'.(time()-3600));

Code (markup):

Or if you want to increase the last hour user downloads then you should increase this because 3600 is the seconds in an hour if im not mistaken.
If i am completely wrong feel free to say so or +rep haha Good luck to you

 

thanks for the above poster.

just look at this

private function SaveInstance() {
		// The file will be a variable in the future
		$DownloadInstance = serialize($this->DownloadInstance);
		$file = fopen('../instance.lst','w');
		fwrite($file,$DownloadInstance);
		fclose($file);
	}
	
	private function PurgeInstance() {
		/*foreach ($this->DownloadInstance as $id => $Instance) {
			if (time() - $Instance['Created'] > 3600 * 5 ) {
				unset($this->DownloadInstance[$id]);
			}
		}
		$this->SaveInstance();*/
		$vhandle = opendir ( "../instances" );
		while ( $filename = readdir ( $vhandle ) ) {
			if ($filename != '.' && $filename != '..' && !is_dir($filename)) {
				$atime = fileatime("../instances/".$filename);
				if (time() - $atime > 3600) {
					unlink("../instances/".$filename);
				}
			}
		}
	}
	
	public function __deconstruct() {
		//$this->SaveInstance();
	}
}

Code (markup):

what this 3600*5
and if (time() - $atime > 3600) {

do here

 

if (time() - $Instance['Created'] > 3600 * 5 ) <== This checks whether 5 hours are passed to creation of this instance of file. If so, unset the download instance id.

if (time() - $atime > 3600) <== checks that if tile was created an hour back, if so, delete the file.
