FPDF is a PHP-based tool that enables the creation of PDF files directly through PHP, making it an alternative to the PDFlib library. The acronym FPDF stands for "free," indicating that it can be utilized and customized without restriction to meet various user requirements. This library functions without the need for additional PHP extensions, aside from Zlib for compression and GD for GIF functionality, and is compatible with PHP versions 5.1 and later, including PHP7 and PHP8. With a range of tutorials available, users can quickly learn to navigate FPDF effectively. Notably, FPDF supports the generation of documents in multiple languages beyond just Western European scripts, accommodating Central, Cyrillic, Greek, and Baltic languages, provided there are suitable TrueType or Type1 fonts available. Additionally, it offers support for UTF-8 encoding. While the document generation speed may not match that of PDFlib, it is still quite reasonable and sufficient for most applications unless specific document precision is required. This versatility makes FPDF a popular choice among developers looking for a straightforward PDF generation solution.
