Adding subfolders to zip file in php (laravel) - php

Question

I have a function which is working fine to create zip file from folder files. But recently I've had need to add sub-folders into my main folder and now I see my function does not add those sub-folders and files in them into generated zip file.
here is what I have currently:
$zip = new ZipArchive;
if ($zip->open(public_path('Downloads/new_zip.zip'), ZipArchive::CREATE) === TRUE)
{
$files = File::files(public_path('new_zip'), true);
foreach ($files as $key => $value) {
$relativeNameInZipFile = basename($value);
$zip->addFile($value, $relativeNameInZipFile);
}
$zip->close();
}
By using code above, let say I have following structure:
new_zip
sample.txt
It works fine to create zip file for my folder.
But
If my folder structure is like:
new_zip
sample.txt
folder_a
file_a.txt
folder_b
folder_c
file_c.txt
Then it ignores everything from folder_a and beyond.
Any suggestions?

You can use this method
The 1st argument is the path to the directory whose data you want to compress
The 2nd argument is the path to the resulting zip file
for your case:
createZipArchive(public_path('new_zip'), public_path('Downloads/new_zip.zip'))
function createZipArchive(string $sourceDirPath, string $resultZipFilePath): bool
{
$zip = new ZipArchive();
if (true !== $zip->open($resultZipFilePath, ZipArchive::CREATE | ZipArchive::OVERWRITE)) {
return false;
}
/** #var SplFileInfo[] $files */
$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($sourceDirPath),
RecursiveIteratorIterator::LEAVES_ONLY
);
foreach ($files as $file) {
$filePath = $file->getRealPath();
if ($file->isDir() || !$filePath) {
continue;
}
$relativePath = substr($filePath, strlen($sourceDirPath) + 1);
$zip->addFile($filePath, $relativePath);
}
return $zip->close();
}
This method will fully reproduce the folder structure of the source directory.
and a little bit of clarification:
To add the directory "test_dir" and the file "test.txt" to the archive - you just need to do:
$zip->addFile($filePath, "test_dir/test.txt");
The RecursiveDirectoryIterator and RecursiveIteratorIterator are used to recursively traverse the directories of the source folder. They are part of the standard php library. You can read about them in the official php documentation
