I wish this helpful for you If there really is need for a continuously running background process, you should look into making a service.

Running a Python script in the background from a PHP file

fixed the issue. Will look into that further You could use exec() to kick off the Python interperator and have it send its output to either a file or to /dev/null with redirection. Using the & operator in the exec call will cause the command to be started and PHP to continue without waiting for a result.

Hope this helps I use something like this. It will dump the exception which caused termination to your syslog, which you can see by examining /var/log/syslog after your script has stopped.

code :

import traceback
import syslog

def syslog_trace(trace):
    '''Log a python stack trace to syslog'''

    log_lines = trace.split('\n')
    for line in log_lines:
        if len(line):
            syslog.syslog(line)

def main():
    # Your actual program here

if __name__ == '__main__':
    try:
        main()
    except:
        syslog_trace(traceback.format_exc())
