@gnganpath I think your prob is about importing Goutte package (check this line require __DIR__ . '/goutte.phar';) !
I hope I'm not too late to reply, did you try updating Goutte to the latest version and importing from composer?

Hi,
Exactly this one kind of search is required for me.
I just copy paste your code. Not working. I have to change any file path or corrections.
