Php ZipArchive add's extra folder - php

Question

zipping some directory on the server I receive extra folder inside zip-archive under Windows and Linux.
Extra folder "3b84" is the ending of using md5(integer) function to set filename inside getExportPaths() method. If I try to make filename shorter - it makes me a zip archive where all files placed in one directory without their subdirectories like "CSS", "fonts" etc.
And one important thing why I'm using md5() - I need to paste into one directory a lot of zip archives. So their name should be unique.
How to fix this and remove such extra folder with a name like "3b84"?
public function actionExportdocument($id)
{
$model = Order::findOne(['id' => $id, 'user_id' => Yii::$app->user->getId()]);
if (!$model) {
throw new BadRequestHttpException('Export not found.');
}
$paths = Order::getExportPaths($model->id, $model->design->path);
$prepareFiles = Order::prepareFiles($paths, $model);
$zip = new ZipArchive();
$zip->open($paths['exportRoot'] . DIRECTORY_SEPARATOR . $paths['exportFile'],
ZipArchive::CREATE | ZipArchive::OVERWRITE);
$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($paths['exportPath']),
RecursiveIteratorIterator::LEAVES_ONLY
);
foreach ($files as $name => $file)
{
// Skip directories (they would be added automatically)
if (!$file->isDir())
{
$filePath = $file->getRealPath();
$relativePath = substr($filePath, strlen($paths['designPath']) + 1);
$zip->addFile($filePath, $relativePath);
}
}
$zip->close();
FileHelper::sendFile($paths['exportRoot'] . DIRECTORY_SEPARATOR . $paths['exportFile'], 'script.zip');
}
Order class contains:
public static function getExportPaths($modelId, $designPath)
{
$paths['orderIdHash'] = md5($modelId);
$paths['designPath'] = \Yii::getAlias('#app') . DIRECTORY_SEPARATOR . 'designs' . DIRECTORY_SEPARATOR . $designPath;
$paths['exportRoot'] = \Yii::getAlias('#webroot') . DIRECTORY_SEPARATOR . 'export-document';
$paths['exportPath'] = $paths['exportRoot'] . DIRECTORY_SEPARATOR . $paths['orderIdHash'];
$paths['exportFile'] = $paths['orderIdHash'] . '.zip';
return $paths;
}
public static function prepareFiles($paths, $model)
{
$exportDir = \Yii::getAlias('#webroot') . DIRECTORY_SEPARATOR . 'export-document';
if (!is_dir($exportDir)) {
mkdir($exportDir);
}
FileHelper::deleteDirectory($paths['exportPath']);
FileHelper::copyRecursive($paths['designPath'], $paths['exportPath']);
$content = '';
foreach ($model->orderTemplates as $template) {
$content .= $template->value;
}
$str = file_get_contents($paths['exportPath'] . DIRECTORY_SEPARATOR . 'index.html');
$str = str_replace("{{CONTENT}}", $content, $str);
file_put_contents($paths['exportPath'] . DIRECTORY_SEPARATOR . 'index.html', $str);
}

Answer 1

If I've read your question correctly; you wish to remove folders like /3b84/ from being generated.
Look inside your Order class:
public static function getExportPaths($modelId, $designPath)
{
$paths['orderIdHash'] = md5($modelId);
$paths['designPath'] = \Yii::getAlias('#app') . DIRECTORY_SEPARATOR . 'designs' . DIRECTORY_SEPARATOR . $designPath;
$paths['exportRoot'] = \Yii::getAlias('#webroot') . DIRECTORY_SEPARATOR . 'export-document';
$paths['exportPath'] = $paths['exportRoot'] . DIRECTORY_SEPARATOR . $paths['orderIdHash'];
$paths['exportFile'] = $paths['orderIdHash'] . '.zip';
return $paths;
}
See $paths['exportPath'] = $paths['exportRoot'] . DIRECTORY_SEPARATOR . $paths['orderIdHash']; ?
Remove that and you your new path will no longer have folders like /3b84/.

The problem was that I've specified wrong $relativePath.
This string was incorrect
$relativePath = substr($filePath, strlen($paths['designPath']) + 1);
And instead of it
$relativePath = substr($filePath, strlen($paths['exportPath']) + 1);
