First question: why use a separate program and language to call a
socket? PHP has two ways of doing it, using the Socket extension and
using the Stream extension. The Stream extension is a little nicer as
you just use standard PHP file functions on it.

To look here, though, you might want to look at the permissions on
client.py to make sure it as well as the requisite paths to get to the
script are readable and executable by the user running your webserver,
or alternatively, your php scripts if running something like fcgi.
