I need to add watermark to a PDF file using PHP without executing external commands like GhostScript.
It must work with PDF 1.7 containing dynamic content (links, forms) so FPDI doesn't work even with its paid version due to the limitations described here https://manuals.setasign.com/fpdi-manual/v2/limitations/ (4.3).
The content is confidential and mustn't be sent to any external API so the watermarking PHP code must be purely on my server.
Any advice?

I just want to ask if there are any free/opensource or are there even any existing PHP class library that can convert HTML to PHP using the tags as its image source?
Because I have created a web app that contains Google Maps in it and now I want to save the generated map, instead of saving it using printscrn I would like to convert it to PDF. Is it even possible?
Can you give me guys a link to the library if ever there are existing ones?
I have already looked for fpdf and tcpdf but on their examples all images is contained on the file directory.
Thanks
There is the library HTML2PDF (on github) licensed under LGPL. It is based on TCPDF and very easy to use.
I have tried and successfully converted html to pdf using wkhtmltopdf[1] binary sometime back (including images).
Download wkhtmltopdf binary which is compatible to your base server o/s and use a php wrapper class similar to this[2] (i haven't tested this wrapper class[2] but it should serve your purpose)
There are plenty of php wrappers available for wkhtmltopdf binary, so you can find one easily if this[2] didn't work well for your purpose.

i'm develop a php application and i need to save a pdf to another pdf but without the images. I need only text of my original pfd. is Possible to do it in php on linux server? I try with pdfbox, but is impossible do it with command line. There are other solutions?
Unless you want text reflow, cpdf is free for non-commercial use.
I have to generate few reports in PDF format with some inventory stats (no graphs, only tables). Additionally, I have to generate some pdf labels for the placed orders and units in a nice tabular format (taking care of landscape orientation and line wrapping) for the web platform. Which PHP API/Library would be best suitable for this purpose. I am using Zend framework but Zend's PDF API is not rich enough to serve the cause.
One option I am considering is to use LateX for generating PDFs.
Advices? Suggestions?
There are several PDF generation libraries and executables.
I've used:
TCPDF
DOMPDF
html2pdf as #redreggae suggested
wkhtmltopdf
Many other alive & dead solutions
They all rendered HTML to PDF. The problem of all (except wkhtmltopdf) was that they all used different (non-standard) rendering engines and results were often different between them and unsatisfying. wkhtmltopdf uses WebKit to interpret the HTML and create a pdf file. I personally prefer wkhtmltopdf after trying/using (in production) all other of the ones listed.. There is one drawback to it - it is an executable and as such it must be called with exec() however this should not be a big issue when proper coding is applied such that you prevent code injection.
If you want something higher level than HTML to PDF converters, you can try PHPJasperXML, it's a renderer for JasperReports on pure PHP.
What I'd like to do
I'd like to allow a user to download a dynamically generated pdf file (certificate). I was thinking of creating a pdf template and just write the user's name on it with PHP, that's the only thing that will be dynamic about this.
How I'd like to do it
Since the application is for a client and I have no idea on what server will he use it I'd like to know if there are ways of achieving this without any extra extensions or whatsoever to be installed on the server. I can assume he has PHP > 5.
Basically read the template pdf and write a string to it then save it to be able to offer for download, all this with PHP?
doing this with pure php on your own will get very messy, so i recommend using FPDF in combination with FPDI (to open your templates). both can easily be added to your projects sources, so you don't need to install any extensions (unless you want to compress your PDFs - in that case you'll need zlib installed).
I need to include pdf files in some webpages, and I'm gettin' in troubles.
The app is a simple newspaper's archive, in which i can read right on page or download as pdf files, one file per page. What my customer can provide me is one pdf file for each page; what my customer wants from me is to navigate them in indexes (with page thumbnail) and have a read from a choosen one direcly in page; I'm using php/mysql.
I started trying out to use the <object> tag with type="application/pdf", but i found it's deprecate 'cause it's not crossplatform at all (there's no support on linux's browsers, but even my windows' firefox 3.5 couldn't show me anything).
I guessed I could transform that pdf in something different (html or simply images are good enough), but the only thing i found is ImageMagick, that I cannot use as I must install on server and I can't, as I'm not admin of that machine.
So, I'm finally looking for suggestions
Thanks
Display the pdf inline using an IFRAME. The thumbnail you can generate with imageMagik. You should be able to use the command line version of ImageMagik to resize and convert to jpg.
edit
Your best bet is to talk to the server admin and have them install php support for ImageMagik then you can use it as a class.
If you can't get support to install on the server, you will have to use the command line version.
You might be able to Google around for a library that wraps the command line, but it would be trivial to write it yourself.
With this in place you can create a large readable black and white png for each page. It should click through to the pdf.
