Run python script from php

manpreet Best Answer 2 years ago

Hello I want to run python script from php. Python script is for reading sensor data. This is python code and it's file name is sensor.py

import bluetooth
bd_addr="(mac address)"
port=1
sock=bluetooth.BluetoothSocket(bluetooth.RFCOMM)
sock.connect((bd_addr.port))
data=""
while 1:
  try:
    data +=sock.recv(1024)
    data_end=data.find('\n')
    if data_end !=-1:
      rec data_end[:data_end]
      print data
      data=data[data_end+1:]
  except Keyboard Interrupt
    break

Now I can read sensor data if I run sensor.py and I want to display sensor data on web server from php without database.

So I save php file in /var/www/html folder. It is code of file and file name is server.php

php
$output=shell_exec('python /home/pi/sensor.py');
echo "
$output
";
?>

And I insert localhost/server.php on web browser but I can't check sensor data because of HTTP 500 ERROR. I thought it is because of permission. So I save another php file in /var/www/html to check my permission and it's file name is test.php

php
echo "HI";
echo date('y-m-d- H:i:s);
?>

And I insert localhost/test.php I can check HI and date. Then why I can't check sensor data if I insert localhost/sensor.php ?
