php7 pthread3 線程鎖（基於文件鎖）

線程內$this-> 調用

public $fpath =  __DIR__ . "/flock.xhxx";

public function lock_lock(){
        $this->fmutex = fopen( $this->fpath,"w+");
        flock( $this->fmutex, LOCK_EX );
    }
    
    public function lock_unlock(){
        flock( $this->fmutex, LOCK_UN );
        fclose( $this->fmutex );
        //unlink( $this->fpath );
    }
