Question:Does anyone know how to programmatically add a overlay or stamp to a PDF file in PHP? So far the best I've come up with is calling the some library with the exec command line but I'd prefer an actual PHP method if one exists. Is there any better solution on VeryPDF?

It is an multi-functional tool for programmers to stamp PDF via stamping image to PDF, stamping text to PDF, or stamping graphics to PDF and process secondary development in various program platforms. And you can use this software toolkit together with any programming language like C#, VB .NET, J# via .NET, Java via JNI, MS Visual Basic, Borland Delphi, MS Office products such as Access and C++ via COM, C and C++ via native C. Please check more information of this software on homepage, in the following part, let us check how to use this software.
Step 1. Free download PDF Stamp COM

- When you use this software, please note all variables must be preceded by the slash (\) character. If the \ character is missing, the variable name will appear in the stamped text. If you want to use the \ character in a stamp it must be listed in the stamp file as \\.
Step 2. Add and overlay/stamp to PDF in PHP.

$id = oTest.veryOpenEx("C:\test.pdf", "C:\out.pdf")
If ($id > 0)
{
$code = PdfStamp.veryAddTextEx($id, 3, "Demo Watermark", 0,
0, 0, 0, 0, 0, 0, 300, "", 0, 0, "", 0)
