PHP Manual :: The SyncSemaphore class



SyncMutex::unlock || SyncSemaphore::__construct || Sync || PHP Manual

(PECL sync >= 1.0.0)

A cross-platform, native implementation of named and unnamed sempahore objects.

A semaphore restricts access to a limited resource to a limited number of instances. Semaphores differ from mutexes in that they can allow more than one instance to access a resource at one time while a mutex only allows one instance at a time.

SyncSemaphore {
/* Methods */
public __construct ([ string $name [, integer $initialval [, bool $autounlock ]]] )
public bool lock ([ integer $wait ] )
public bool unlock ([ integer &$prevcount ] )
}
