Following script was very helpful to me for compressing A folder (including all sub folders and files in it) using PHP:
<?php
$the_folder = 'path/foldername';
$zip_file_name = 'archived_name.zip';
$download_file= true;
//$delete_file_after_download= true; doesnt work!!
class FlxZipArchive extends ZipArchive {
/** Add a Dir with Files and Subdirs to the archive;;;;; @param string $location Real Location;;;; @param string $name Name in Archive;;; @author Nicolas Heimann;;;; @access private **/
public function addDir($location, $name) {
$this->addEmptyDir($name);
$this->addDirDo($location, $name);
} // EO addDir;
/** Add Files & Dirs to archive;;;; @param string $location Real Location; @param string $name Name in Archive;;;;;; @author Nicolas Heimann
* @access private **/
private function addDirDo($location, $name) {
$name .= '/';
$location .= '/';
// Read all Files in Dir
$dir = opendir ($location);
while ($file = readdir($dir))
{
if ($file == '.' || $file == '..') continue;
// Rekursiv, If dir: FlxZipArchive::addDir(), else ::File();
$do = (filetype( $location . $file) == 'dir') ? 'addDir' : 'addFile';
$this->$do($location . $file, $name . $file);
}
} // EO addDirDo();
}
$za = new FlxZipArchive;
$res = $za->open($zip_file_name, ZipArchive::CREATE);
if($res === TRUE)
{
$za->addDir($the_folder, basename($the_folder));
$za->close();
}
else { echo 'Could not create a zip archive';}
if ($download_file)
{
ob_get_clean();
