Cannot get php to work

I posted my code below. I do not get any error that I can see but it does not display on the screen correctly and if I click the link it just errors. I have consulted the oracle (google) without any luck
I verified php is enabeled all the basic standard stuff: etc.

directory structure
/var/www/http

test/192
test/192/images
test/192/images/123test.jpg
test/192/images/thumbs
does not create any of the thumbnails.

I put this same code on an olderversion of linux centos 7.x and it works just fine. any help would be much appreciated:

Thank you
Tony
