There are several libraries and tools available for editing PDF files in PHP. Some popular options include:

- TCPDF: This is another popular, open-source PHP library for generating PDF documents. It has a wide range of features, including support for Unicode, barcodes, encryption, and more.
- pdflib: This is a commercial library for generating and manipulating PDF files in PHP. It offers a range of advanced features, including support for interactive forms, annotations, and layer manipulation.

Before choosing a library or tool for editing PDF files in PHP, it’s important to consider your specific needs and requirements. Some libraries may be more suitable for certain tasks than others, so it’s a good idea to research and compare the different options before making a decision.
Here is a simple example of how you could use the FPDF library to edit a PDF file in PHP:
<?php // include the FPDF library require('fpdf.php'); // create a new PDF document $pdf = new FPDF(); // add a page to the document $pdf->AddPage(); // set the font and font size $pdf->SetFont('Arial', 'B', 16); // add some text to the document $pdf->Cell(40, 10, 'Hello World!'); // save the PDF to a file $pdf->Output('edited.pdf', 'F'); ?>
This code creates a new PDF document, adds a page to it, sets the font and font size, and then adds some text to the document. Finally, it saves the PDF to a file named “edited.pdf”.
You can use similar methods and functions from the FPDF library to add other elements to the PDF, such as images, tables, and shapes. You can also use the library’s formatting options to control the layout and appearance of the document.
Keep in mind that this is just a very basic example, and there are many more features and options available with the FPDF library. You can find more information and examples in the library’s documentation.
