how to run Python script from php

Question

I want to run python script from php. this is my python code. It is saved in /home/pi and name of file is hello.py

#! /usr/bin/python

import bluetooth

bd_addr="xx:xx:xx:xx:xx:xx"
port=1
sock=bluetooth.BluetoothSocket(bluetooth.RFCOMM)
sock.connect((bd_addr.port))
data=""
while 1:
  try:
    data +=sock.recv(1024)
    data_end=data.find('
')
    if data_end!=-1:
      rec=data[:data_end]
      print datas
      data=data[data_end+1:]
    except KeyboardInterrupt:
      break

And here is my php code. It is saved in /var/www/html and name of file is php.php

<?php
$output=shell_exec('ls -l /home/pi/hello.py');
echo "<pre>$output</pre>";
?>

And I insert localhost/php.php in chrome, it displays

-rw-r-r- 1 pi pi 378 Mar 8 12:07 /home/pi/hello.py

what is the problem??

As pointed out by Jon Stirling, you are using "ls" to only listing the content of the folder or to check whether the file exist in that folder. To run the Python code, you need to change the PHP file into something like this:

<?PHP
$output=shell_exec('./hello.py');
echo "<pre>$output</pre>";
?>
