Project Description:
I am needing a PHP code which will take a users input file (.doc, .docx, .pub, or .pdf(if already in that format)+ any others a bonus) and convert it to .pdf on upload. I need the file to be stored in a folder (folder name created as $_SESSION['UserID'], and the file name to be corrected to reflect .pdf extension change and then stored in the database against $_SESSION['UserID']. Any takers?
