This package provides a PHP integration package for the RoadRunner Lock plugin, which allows for easy management of distributed locks in PHP applications. The plugin provides a fast, lightweight, and reliable way to acquire, release, and manage locks in a distributed environment, making it ideal for use in high-traffic web applications and microservices.
Make sure that your server is configured with following PHP version and extensions:
- PHP 8.1+
You can install the package via composer:
composer require roadrunner-php/lockuse RoadRunner\Lock\Lock;
use Spiral\Goridge\RPC\RPC;
require __DIR__ . '/vendor/autoload.php';
$lock = new Lock(RPC::create('tcp:https://127.0.0.1:6001'));Locks a resource so that it can be accessed by one process at a time. When a resource is locked, other processes that attempt to lock the same resource will be blocked until the lock is released.
$id = $lock->lock('pdf:create');
// Acquire lock with ttl - 10 seconds
$id = $lock->lock('pdf:create', ttl: 10);
// or
$id = $lock->lock('pdf:create', ttl: new \DateInterval('PT10S'));
// Acquire lock and wait 5 seconds until lock will be released
$id = $lock->lock('pdf:create', wait: 5);
// or
$id = $lock->lock('pdf:create', wait: new \DateInterval('PT5S'));
// Acquire lock with id - 14e1b600-9e97-11d8-9f32-f2801f1b9fd1
$id = $lock->lock('pdf:create', id: '14e1b600-9e97-11d8-9f32-f2801f1b9fd1');Locks a resource for shared access, allowing multiple processes to access the resource simultaneously. When a resource is locked for shared access, other processes that attempt to lock the resource for exclusive access will be blocked until all shared locks are released.
$id = $lock->lockRead('pdf:create', ttl: 10);
// or
$id = $lock->lockRead('pdf:create', ttl: new \DateInterval('PT10S'));
// Acquire lock and wait 5 seconds until lock will be released
$id = $lock->lockRead('pdf:create', wait: 5);
// or
$id = $lock->lockRead('pdf:create', wait: new \DateInterval('PT5S'));
// Acquire lock with id - 14e1b600-9e97-11d8-9f32-f2801f1b9fd1
$id = $lock->lockRead('pdf:create', id: '14e1b600-9e97-11d8-9f32-f2801f1b9fd1');Releases an exclusive lock or read lock on a resource that was previously acquired by a call to lock()
or lockRead().
// Release lock after task is done.
$lock->release('pdf:create', $id);
// Force release lock
$lock->forceRelease('pdf:create');Checks if a resource is currently locked and returns information about the lock.
$status = $lock->exists('pdf:create');
if($status) {
// Lock exists
} else {
// Lock not exists
}Updates the time-to-live (TTL) for the locked resource.
// Add 10 seconds to lock ttl
$lock->updateTTL('pdf:create', $id, 10);
// or
$lock->updateTTL('pdf:create', $id, new \DateInterval('PT10S'));composer testThe MIT License (MIT). Please see License File for more information.
