problems with exec php

Question

I made the following command in php

    $comando="C:\Python27\python.exe programa.py";
    echo $comando;

in the python file

    print resultado;

This result variable has content formed in json

    {
       "algumacoisa":"algumacoisa"
    }

When I do the command prompt:

    python.exe programa.py

It returns the contents correctly, but when I do with php

    php site.php

It only returns the last line of json which is only one

    }

Answer 1

Solved

It worked using the command

    passthru($comando, $resultado); echo $resultado;
