thank you for your reply.

but what i really meant is how to modify pdf files witout using FPDFLib library or any other libraries where i have to buy the license.
meaning modifying pdf files using only php scripts.
i just read some articles on creating pdf files using only
php scripts. im just getting into how to modify the files.

i guess i didnt write my questions correctly.
im sorry that i mislead you guys that read the message.

but thank you so much.
