How Can PHP Libraries Help Extract Data and Coordinates from PDF Files?

Reading and Extracting Data from PDF Files in PHP

To read PDF files and extract text layer coordinates in PHP, you can leverage the capabilities of several libraries.

FPDF and FPDI

FPDF (http://www.fpdf.org/) and FPDI (http://www.setasign.de/products/pdf-php-solutions/fpdi/) are widely used for working with PDFs in PHP. They allow you to open PDF files, search for text layers, retrieve their contents, and extract their coordinates. By utilizing these functions, you can generate a mapping of office furniture locations to x/y coordinates.

TCPDF

TCPDF (https://tcpdf.org/) is another popular PHP library for managing PDFs. It provides similar functionality to FPDF but with additional features. Using TCPDF, you can read PDF files, search for text layers, and retrieve their coordinates. This enables you to efficiently map seat locations within a floor plan.

PDF Parser

PDF Parser (https://github.com/mikehaertl/php-pdfi) is a modern and versatile library for parsing PDF files in PHP. It offers an API for extracting text from PDF documents, including the coordinates of text layers. By integrating PDF Parser into your code, you can quickly and accurately identify office furniture locations within the floor plan PDF.

These libraries provide a range of options for reading PDF files in PHP and extracting text layer data. Select the one that best aligns with your requirements and project constraints.
