README
PHP library for handling chunk uploads. Library contains helper methods for:
- Testing if uploaded file chunk exists.
- Validating file chunk
- Creating separate chunks folder
- Validating uploaded chunks
- Merging all chunks to a single file
This library is compatible with HTML5 file upload library: https://github.com/flowjs/flow.js
How to get started?
Setup Composer: https://getcomposer.org/doc/00-intro.md
Run this command in your project:
composer require flowjs/flow-php-server
This will create a vendor directory for you, which contains an autoload.php file.
Create a new php file named upload.php
:
//Path to autoload.php from current location require_once './vendor/autoload.php'; $config = new \Flow\Config(); $config->setTempDir('./chunks_temp_folder'); $request = new \Flow\Request(); $uploadFolder = './final_file_destination/'; // Folder where the file will be stored $uploadFileName = uniqid()."_".$request->getFileName(); // The name the file will have on the server $uploadPath = $uploadFolder.$uploadFileName; if (\Flow\Basic::save($uploadPath, $config, $request)) { // file saved successfully and can be accessed at $uploadPath } else { // This is not a final chunk or request is invalid, continue to upload. }
Make sure that ./chunks_temp_folder
path exists and is writable. All chunks will be saved in this folder.
If you are stuck with this example, please read this issue: How to use the flow-php-server
Advanced Usage
$config = new \Flow\Config(); $config->setTempDir('./chunks_temp_folder'); $file = new \Flow\File($config); if ($_SERVER['REQUEST_METHOD'] === 'GET') { if ($file->checkChunk()) { header("HTTP/1.1 200 Ok"); } else { header("HTTP/1.1 204 No Content"); return ; } } else { if ($file->validateChunk()) { $file->saveChunk(); } else { // error, invalid chunk upload request, retry header("HTTP/1.1 400 Bad Request"); return ; } } if ($file->validateFile() && $file->save('./final_file_name')) { // File upload was completed } else { // This is not a final chunk, continue to upload }
Delete unfinished files
For this you should setup cron, which would check each chunk upload time. If chunk is uploaded long time ago, then chunk should be deleted.
Helper method for checking this:
\Flow\Uploader::pruneChunks('./chunks_folder');
Cron task can be avoided by using random function execution.
if (1 == mt_rand(1, 100)) { \Flow\Uploader::pruneChunks('./chunks_folder'); }
