How can i detect hidden text from a pdf file using php. I know that there are different ways on how to hide a text from a pdf file. So I need to know if there is a way to check a pdf file if it has a hidden text in it using php.
I am still not familiar with the php libraries for pdf so I need to know which one does the job for this.

I created a PDF file with some fields. I need users to fill out a HTML form and use these data to populate the fields in this file.
Right now, users have the link to that PDF file. They fill out the form, but they can't save it nor email it. I need the file to keep the values users type (perhaps save those values as the file' default) and allow them to save that copy in their devices, to latter email the file.
I was reading that PHP-PDF is limited and that there's other solutions out there. I am not sure if the default PHP-PDF functions are enough or if I'll need to look for an external PDF solution?
This appears like a simple server-side form filling task.
An industrial-strength solution would be using FDFMerge by Appligent, where you could, for example have already a PDF for gathering the primary information, submit as FDF, and feed this FDF into the "big" Template PDF. Or, if you have to add more data server-side, you might also submit as HTML POST, create the FDF on the fly (pretty easy, because FDF is a structured text format), and feed that into FDFMerge.
If you prefer developing a server-side solution using PDF creating/modifying libraries, you dan do so, using iText, or pdflib or others allowing server-side filling.
It essentially comes to which way would be the most cost and time efficient way to solve the problem.
I have a PDF form and i want to import this PDF Form in PHP and then populate all fields from database then create new PDF.
is that possible?
If yes then please guide me how can i inert data in already make PDF forms.
Here is the PDF form file which i want to Import.

If you do take into account your working time etc. you might actually consider commercial server-side form filling tool, such as FDFMerge by Appligent (for simple filling, the Lite version would be sufficient). In this case, you won't need to noodle around the PDF, trying to interpret it, and attempting to write something back.
In this scenario, you would export an FDF from the database, which is rather easy to accomplish, as FDF is a simple text file. How it has to look can be found with ease as well, by taking the form, filling it out, and exporting the data as FDF. And then, the rest is "filling out the blanks".
For using libraries to do server-side filling, links have already been provided. Just a note: make sure that you will get a good and functional PDF, by relying on well-reputated libraries.
I am trying to use PHP to read the text from a PDF file that is stored in a mysql database. I tried using class.pdf2text.php, which works with an actual file. I tried to use the MYSQL_RESULT variable with the pdf file contents with that class, but it doesn't work. I've got to be missing something really easy, I just know it.
Basically, this is what I'm trying to do:
I have a database with PDF files. I need to convert a PDF from that database to text and then search on that text for certain data. Is there a way to do this without creating external files in PHP?
I have created new PDFs many times using Zend and PHP. But Now I have a patient form in PDF format and I have to fill that form using my application. How can I print text on existing PDF file with already have some text. Is it possible ?
Thanks
I haven't done it, but it certainly seems possible. See Zend_Pdf::load(), for example. It seems like you ought to be able to load the PDF, manipulate it, and save then save it somewhere.
Last time I had to do this, Zend_Pdf wasn't around, and I ended up using fpdf/fpdi, which was ugly but worked fine.
Does the PDF contain form fields ? If so you can use FDF type functions.
See Filling PDF Forms with PHP - there should be a solution in there somewhere.
I am looking for some way to code a function (I'm open to any language or library at this point) to take an already existing PDF file as input and return a modified PDF file that links certain words to different URLs. I know PHP and ColdFusion both have good tools for dealing with PDF's, but I haven't been able to find anything that works.
I've been doing this by going through Acrobat and linking the text by hand and was wondering if there was any way to automate the procedure.
Thanks!
With ColdFusion you can extract the text with DDX (see Extracting text from a PDF document on the page), modify it using search/replace and generate new document.
If I understand what you're trying to do, you should be able to use CFPDF (http://livedocs.adobe.com/coldfusion/8/htmldocs/Tags_p-q_02.html#2922772) to read the pdf file into a ColdFusion variable, replace whatever content you want in that variable, then save the content back to pdf.
