我试图让 4 个 LED 灯和关闭或组合状态，但这些 LED 中只有 2 个实际工作，即 17 ,22。当我单击按钮时，其余部分似乎没有响应

     LED Control:
     <form method="get" action="gpio.php">
             <input type="submit" value="ON" name="on">
             <input type="submit" value="OFF" name="off">
     </form>
     <?php
     $setmode17 = shell_exec("/usr/local/bin/gpio -g mode 17 out");
     $setmode22 = shell_exec("/usr/local/bin/gpio -g mode 22 out");
     $setmode27 = shell_exec("/usr/local/bin/gpio -g mode 27 out");
     $setmode04 = shell_exec("/usr/local/bin/gpio -g mode 04 out");
     if(isset($_GET['on'])){
             $gpio_on = shell_exec("/usr/local/bin/gpio -g write 17 1");
             $gpio_on = shell_exec("/usr/local/bin/gpio -g write 22 1");
             $gpio_on = shell_exec("/usr/local/bin/gpio -g write 27 1");
             $gpio_on = shell_exec("/usr/local/bin/gpio -g write 04 1");
             echo "LED is on";
         }
         else if(isset($_GET['off'])){
             $gpio_on = shell_exec("/usr/local/bin/gpio -g write 17 0");
             $gpio_on = shell_exec("/usr/local/bin/gpio -g write 22 0");
             $gpio_on = shell_exec("/usr/local/bin/gpio -g write 27 0");
             $gpio_on = shell_exec("/usr/local/bin/gpio -g write 04 0");
             echo "LED is off";
         }
         ?>
         </body>
 </html>

这是我的 LED 控制页面的代码，只有 17 和 22 工作，wiringpi 中实际 raspi3 的接线数/针数是否有差异？还是我做错了什么？
