Here is a simple function which zips folders with all sub folders or only a simple file... the $data var can be a string or an array...
<?php
public function un_zip($data,$arcpf,$mode='zip',$obj=''){
$absoluterpfad = 'YOUR_BASE_PATH';
$arcpf = $absoluterpfad.DS.$arcpf;
if(is_object($obj)==false){
$archiv = new ZipArchive();
$archiv->open($arcpf,ZipArchive::CREATE);
}else{$archiv =& $obj;}
if($mode=='zip'){
if(is_array($data)==true){
foreach($data as $dtmp){
$archiv =& un_zip($dtmp,$arcpf,'zip',&$archiv);
}
}else{
if(is_dir($data)==true){
$archiv->addEmptyDir(str_replace($absoluterpfad.DS,'',$data));
$files = scandir($data);
$bad = array('.','..');
$files = array_diff($files,$bad);
foreach($files as $ftmp){
if(is_dir($data.DS.$ftmp)==true){
$archiv->addEmptyDir(str_replace($absoluterpfad.DS,'',$data.'/'.$ftmp));
$archiv =& un_zip($data.DS.$ftmp,$arcpf,'zip',&$archiv);
}elseif(is_file($data.DS.$ftmp)==true){
$archiv->addFile($data.DS.$ftmp,str_replace($absoluterpfad.DS,'',$data.'/'.$ftmp));
}
}
}elseif(is_file($data)==true){$archiv->addFile($data,str_replace($absoluterpfad.DS,'',$data));}
}
}
if(is_object($obj)==false){$archiv->close();}
else{return $archiv;}
if($mode=='unzip'){$archiv->extractTo($data);}
}
?>
