why not use the api? text-processing.com/docs/sentiment.html - user557846
Yeah, if you're happy with what the demo does, then use the API. If not, the source code for the classifier is here, and you can change how it works and the corpus you're using yourself. - Marius

Here is an idea.

You can use File Handling in your Php code and write the content of $data to a file. Then instead of passing $data as argument, read the file contents from your python code, perform whatever algorithm you want to and print the result so that it gets stored in $tmp.

You can wrap $data by single quotes 

$data = htmlentities($data, ENT_QUOTES);
$tmp = exec("/home/Ismath/Desktop/check.py '$data'");

python:

import sys
from HTMLParser import HTMLParser
print HTMLParser().unescape(sys.argv[1])
