README

Connecting to Redis:

RedisLock::connect('tcp://host:port');

Or to just connect to localhost and default port:

RedisLock::connect();

Acquiring a Lock:

$lock = RedisLock::lock('resource');
if($lock) {
    doSomething();
}

This will attempt to acquire a lock for the named resource. If successful, the return value is a RedisLock object. If the resource was already locked, the return value will be +false+.

Releasing the Lock:

RedisLock::release($lock);

Make sure to release the lock once you're done with it, so another client can acquire it.

Lock Expiration

If your client acquires a lock and then dies before releasing it, the lock will expire after a certain amount of time (default 5 minutes). You can set your own lock expiration when acquiring the lock like so: $lock = RedisLock::lock('resource', $expiration_in_seconds);
