The Best Zip Function

hi
my 6th code is very useful, you can zip your file by this:

<?class dZip{	var $filename;	var $overwrite;		var $zipSignature = "\x50\x4b\x03\x04"; // local file header signature	var $dirSignature = "\x50\x4b\x01\x02"; // central dir header signature	var $dirSignatureE= "\x50\x4b\x05\x06"; // end of central dir signature	var $files_count  = 0;	var $fh;		Function dZip($filename, $overwrite=true){		$this->filename  = $filename;		$this->overwrite = $overwrite;	}	Function addDir($dirname, $fileComments=''){		if(substr($dirname, -1) != '/')			$dirname .= '/';		$this->addFile(false, $dirname, $fileComments);	}	Function addFile($filename, $cfilename, $fileComments='', $data=false){		if(!($fh = &$this->fh))			$fh = fopen($this->filename, $this->overwrite?'wb':'a+b');				// $filename can be a local file OR the data wich will be compressed		if(substr($cfilename, -1)=='/'){			$details['uncsize'] = 0;			$data = '';		}		elseif(file_exists($filename)){			$details['uncsize'] = filesize($filename);			$data = file_get_contents($filename);		}		elseif($filename){			echo "<b>Cannot add $filename.

Hello, I work with my friends on open source project (https://sourceforge.net/directory/os:windows/
wversions) developed in PHP. It can be used for exchange, file management and version control through the web. I have found your source code with class dZip on internet and I would like to request your permission to use in it our project, if it is possible. Looking forward for your responseBest regardspetdin
