Calling Python in PHP

Question

I have a Python script I recently wrote that I call using the command line with some options  I now want a very thin web interface to call this script locally on my Mac   I don t want to go through the minor trouble of installing mod python or mod wsgi on my Mac  so I was just going to do a system   or popen   from PHP to call the Python script   Any better ideas  Thanks in advance

You can run a python script via php  and outputs on browser   Basically you have to call the python script this way    command    python  path to python script py 2 gt  amp 1    pid   popen   command  r    while   feof   pid        echo fread  pid  256    flush     ob flush     usleep 100000     pclose  pid     Note  if you run any time sleep   in you python code  it will not outputs the results on browser   For full codes working  visit How to execute python script from php and show output on browser

I do this kind of thing all the time for quick-and-dirty scripts   It s quite common to have a CGI or PHP script that just uses system popen to call some external program   Just be extra careful if your web server is open to the internet at large   Be sure to sanitize your GET POST input in this case so as to not allow attackers to run arbitrary commands on your machine

Depending on what you are doing  system   or popen   may be perfect   Use system   if the Python script has no output  or if you want the Python script s output to go directly to the browser   Use popen   if you want to write data to the Python script s standard input  or read data from the Python script s standard output in php   popen   will only let you read or write  but not both   If you want both  check out proc open    but with two way communication between programs you need to be careful to avoid deadlocks  where each program is waiting for the other to do something   If you want to pass user supplied data to the Python script  then the big thing to be careful about is command injection   If you aren t careful  your user could send you data like    evilcommand    and make your program execute arbitrary commands against your will   escapeshellarg   and escapeshellcmd   can help with this  but personally I like to remove everything that isn t a known good character  using something like  preg replace     a-zA-Z0-9          str

Your call python file php should look like this    lt  php      item  Everything is awesome          tmp   exec  py py  item        echo  tmp    gt    This executes the python script and outputs the result to the browser  While in your python script the  sys argv 1    variable will bring in all your arguments  To display the argv as a string for wherever your php is pulling from so if you want to do a text area   import sys  list1       join sys argv 1     def main      print list1  if   name         main         main
