Comes with other actions:

Unzip the zip file

public  function unzip_file ( $ File , $ dir ) { 

        // instantiate an object 

        $ zip = new new ZipArchive (); 

        // open the zip file, if you open a failure return message 

        IF ( $ zip -> Open ( $ File ) ==! TRUE ) { 

          Die ( "Could not Open Archive" ); 

        } 

        // extract the compressed files to the specified directory 

        $ zip -> extractTo ( $ dir ); 

        // close the zip archive 

        $ zip -> use Close ();   

    }

Get-extracting file directory

public  function loopFun ( $ dir )   

    {   

        $ handle = opendir ( $ dir . "." ); 

        // define the arrays to store the file name 

        $ array_file = Array (); 

        the while ( false ! == ( $ File = readdir ( handle $ ))) 

        { 

            IF ( $ file ! "." && = $ file ! = ".." ) { 

                $ array_file [] = $ the dir .. '/' $ file ; // output filename 

            }

        }

        closedir($handle);

        return $array_file;

        //print_r($array_file);

    }
