I have already built a database and using PHP I can edit, delete, etc... from the database. I dont need a PDF creator or reader, The PDF will be uploaded and already created, I need to open it to edit NO CREATE I need an app which I can integrate into my app to edit pdf. I should be in such a way that when I click on the name on the database the file will be opened using the PDF editor automatically such that the user can edit the PDF ( The PHP and MySQL part is okay)(PDF is already on server) Can you help by suggestion what PDF editor can I use and how to use it or even alternatives to what I want Also, guide me on how to integrate and use the app Thanks
