Difference between calling a python script by terminal and by PHP? Where is the Error?

Question

I have a PHP script, that calls a python script by

$call_python = \"python ../python/lp_3.py \".$author;
$python_output = Null;
$mystring = exec($call_python         


        

Answer 1

$call_python = "/opt/local/bin/python2.6 ../python/lp_3.py ".$author;
$python_output = Null;
$mystring = exec($call_python, $output_python);

did the job. Like @AJ pointed out, I had to tell python which version to chose. I chose a version where MySQLdb was available and all was fine.
