send command to open door

[IrisDande]

thank you for your code, I wanna ask a question about door lock. as normal, when staff scan fingerprint on ZK device, door lock will release and staff able to open door. So my question is could you help me check and write a quick code to sent command open door?

You can't do it because ZK library is only for read the attendance data from the device.

You can use application like Wireshark to see the command sent to your device or you can open API documentation of your device

Actually ZK device has a connection for door open. You don't need any code but a connection to device and buy ZK door contact device too. Search online

Hi, I think this will help you. This code successful works in my system.

define('CMD_UNLOCK', 31); public function dooropen() { $command = CMD_UNLOCK; $byte = chr(10); // duration of delay unlocking $command_string = $byte; return $this->execCommand($command, $command_string); }
