How can I implement PDF parsing in PHP? by KulfiSoftware
How can I implement PDF parsing in PHP? Try not to re-invent the wheel. Use a library:
Portable Document Format (PDF) is a file format used to present and exchange documents reliably, independent of software, hardware, or operating system. Invented by Adobe, PDF is now an open standard maintained by the International Organization for Standardization (ISO). PDFs can contain links and buttons, form fields, audio, video, and business logic. They can also be signed electronically and are easily viewed using free Acrobat Reader DC software.
In 1991, Adobe co-founder Dr. John Warnock launched the paper-to-digital revolution with an idea he called The Camelot Project. The goal was to enable anyone to capture documents from any application, send electronic versions of these documents anywhere, and view and print them on any machine. By 1992, Camelot had developed into PDF. Today, it is the format trusted by businesses around the world.
Warnock’s vision is alive, well, and evolving. When you save a document or image as an Adobe PDF, it looks just the way you intended it to. While many PDFs are simply pictures of pages, Adobe PDFs preserve all the data in the original file – even when text, graphics, spreadsheets, and more are combined in a single file.
