php script works when manually run but only partially works as cron job (will not write files to directory)

I'll start by saying I am very new to linux in general. What I have is a php script I wrote that fetches images from posts on reddit.com hides the post and adds the link to an array, then saves all the images in the array. when I type something like: "php cron.php" as root it runs fine, but whenever crontab runs it the script only hides all the posts but never saves the images. To me it sounds like a problem with permissions by the cron user. Ive been messing with it for hours and recently changed it the www-data user's crontab with: "su -l www-data -c 'crontab -e'" but still no cigar, since its a cron job I suppose its running silently and not giving me any errors. If anyone could show me how to display these messages it would surely help debugging. Thanks.

you're running php cron.php under yourself, but cron works under different user and even if you're trying to run it under www-data it is still different user from yourself

simple solution: check what right has folder where php tries to write, set them to 0777 to test, check if cron script is successful

then you can have different options, like - set folder's owner to cron and set 0755 or move cron user to the same group as you're
