This library is for simultaneous write on a single file with locking mechanism by PHP flock function. It uses the unix semaphore to lock the file and hence a safe application to store data in a single file shared by multiple methods.

composer require ferdous/flock-write

How to add

Add the following operations to the namespace

use Ferdous\FileLockWrite\FileOperation;
use Ferdous\FileLockWrite\LockService;

Now you are ready to add the functionality by creating the object

$lockService = new LockService();
$opObj = new FileOperation($filepath, $filename,  $lockService, $data);

Operations

• Truncate File

  $opObj->truncateFile() 

• Write File with Exclude Lock

• Read File with Shared Lock

  $opObj->readDataFromFile()
