Zip Extraction

[Stewart]

I'm trying to get hold of some script to extract .zip files and possibly one or 2 other compressed filetypes like Gzip. The problem is it needs to be able to run in environments where the Zip library isn't available. I've been having a look around, but all i could find were scripts using the library.Can anyone help me out here please?

I use this:http://www.phpconcept.net/pclzip/index.en.phpDownload the class definition file (pclzip.lib.php), include that file in your PHP script, and you can work with zip files. Here is a little chunk of code that I use for a gallery when someone uploads a zip file full of images. This will extract the zip file to a temporary directory (zip_temp), automatically chmod each file that gets extracted, and extract all files that are nested in folders or subfolders of the zip archive. And then it adds each image to the database.

if ($errStr == "" && isset($filename))  {	  $zipfile = new PclZip($filename);	  $zipfile->extract(PCLZIP_OPT_PATH, "zip_temp/", PCLZIP_OPT_SET_CHMOD, 0777, PCLZIP_OPT_REMOVE_ALL_PATH);	$path = $temp_save . "zip_temp";	  $dir_handle = opendir($path);	  $path .= "/";	$galID[0] = 0;	if (mysql_query("INSERT INTO `galleries` (`name`, `desc`) VALUES ('" . mysql_escape_string($name) . "', '" . mysql_escape_string($desc) . "');"))	  $galID[0] = mysql_insert_id();	else	  echo mysql_error();	while ($galID[0] != 0 && (false !== ($file = readdir($dir_handle))))	{		$valid = false;	  if ($file != "." && $file != ".." && !is_dir($path . $file))	  {		$components = explode(".", $file);		switch (strtolower($components[count($components) - 1]))		{		  case 'gif':		  case 'jpg':		  case 'jpeg':		  case 'wbmp':		  case 'png':			$valid = true;			break;		}	  }	  if ($valid)	  {		$data = fread(fopen($path . $file, "rb"), filesize($path . $file));		add_image($path . $file, $data, $galID, $file);		$nr++;	  }	  if ($file != "." && $file != "..")	  {		  chmod($path . $file, 0777);		  if (is_dir($path . $file))		  rmdir($path . $file);		else		  unlink($path . $file);	  }	}	closedir($dir_handle);	$i = 1;	$result = mysql_query("SELECT `imgID` FROM `in_gallery` WHERE `galID`={$galID[0]};");	while ($row = mysql_fetch_assoc($result))	{		mysql_query("UPDATE `gallery_images` SET `desc`='$i of $nr' where `imgID`={$row['imgID']};");	  $i++;	}  }
