ensures that there can only be one call at runtime; prevents multiple calls at runtime.
As long as the runtime takes, Lock prevents multiple calls.
create(string $sKey = '', bool $bReturn = false)
simply note the following command at the place you want to be protected from multiple calls.
In most cases this would be inside a Controller method.
Example
public function index()
{
Lock::create();
...
}This command creates a lock folder inside your cache folder during runtime.
When runtime is over, the lock folder will be removed automatically.
