Zip/Unzip with php - php

Question

I am doing a backup module, I need to zip all the webapp folder, I use this method:
function agregar_zip($dir, $zip){
if (is_dir($dir)) {
if ($da = opendir($dir)) {
while (($archivo = readdir($da))!== false) {
if (is_dir($dir . $archivo) && $archivo!="." && $archivo!=".."){
agregar_zip($dir.$archivo . "/", $zip);
}elseif(is_file($dir.$archivo) && $archivo!="." && $archivo!=".."){
$zip->addFile($dir.$archivo, $dir.$archivo);
}
}
closedir($da);
}
}
}
$zip = new ZipArchive();
$dir = Yii::app()->basePath.'/../';
$rutaFinal="c:/xampp/htdocs/";
$archivoZip = "backup.zip";
if($zip->open($archivoZip,ZIPARCHIVE::CREATE)===true) {
agregar_zip($dir, $zip);
$zip->close();
#rename($archivoZip, "c:/xampp/htdocs/backup.zip");
if (file_exists($rutaFinal.$archivoZip)){
}else{
Yii::app()->params['errores'] = Yii::app()->params['errores']."</br>No se ha creado el ZIP con éxito.";
}
}
When I open the file.zip, I have this structure:
C:/->xampp->htdocs->mywebapp(Here is all I need)
But If I do "extract here" Its unzip the right content, but If I do with php it create a folder in destination called xampp, inside it htdocs, inside it mywebapp(With the right content).
I need to zip only the app folder not all the route. This way when I unzip with php only unzip app folder.

Answer 1

I think you need to remove the "/../" from this line
$dir = Yii::app()->basePath.'/../';
should be
$dir = Yii::app()->basePath;

Answer 2

There is better way to make zip with yii.
Yii has a zip extension.
Usage example from the docs above:
Introduce EZip to Yii. Add definition to CWebApplication config file (main.php)
'components'=>array(
...
'zip'=>array(
'class'=>'application.extensions.zip.EZip',
),
...
),
Now you can access EZip methods as follows:
$zip = Yii::app()->zip;
$zip->makeZip('./','./toto.zip'); // make an ZIP archive
var_export($zip->infosZip('./toto.zip'), false); // get infos of this ZIP archive (without files content)
var_export($zip->infosZip('./toto.zip')); // get infos of this ZIP archive (with files content)
$zip->extractZip('./toto.zip', './1/'); //
