I am doing something similar to an eSign and need to find the text tags (e.g. “{{signature}}”) in a PDF document (the page, position in page and the text) and then delete/hide them. I then need to put a signature image in the saved positions.

I have found and have numerous ways to insert the signature image, but I can’t find a way to get the text tag properties and delete it in PHP or with a command line.
