The "php100 translation" PDF full name Portable Document format, translated as portable, is an Adobe company-launched document format. The PDF has an OS-independent feature that makes it an ideal document format for electronic document distribution and digital information dissemination on the Internet. Today we'll discuss how to create PDF documents using PHP and modify PDFs using PHP.

To use PDF documents in PHP, we need to use the Tcpdf package, a class that PHP uses to read PDFs.

PHP Create PDF document

You can download the Tcpdf package from the link given below.

Tcpdf-php class for pdf:http://sourceforge.net/projects/tcpdf/files/

This is a free and easy-to-use plug-in package, and here are some examples to show how to work with the Tcpdf package.

Example one: Using PHP to generate a simple PDF document

 
 
  1. require_once ('.. /config/lang/eng.php ');
  2. require_once ('.. /tcpdf.php ');
  3. //Create new PDF document
  4. $pdf = New TCPDF (pdf_page_orientation, Pdf_unit, Pdf_page_format, True, ' UTF-8 ', false);
  5. //Set Document information
  6. $pdf ->setcreator (Pdf_creator);
  7. $pdf ->setauthor (' Nicola asuni ');
  8. $pdf ->settitle (' TCPDF Example 002 ');
  9. $pdf ->setsubject (' TCPDF Tutorial ');
  10. $pdf ->setkeywords (' TCPDF, PDF, example, Test, guide ');
  11. //Remove default Header/footer
  12. $pdf ->setprintheader (FALSE);
  13. $pdf ->setprintfooter (FALSE);
  14. //Set default monospaced font
  15. $pdf ->setdefaultmonospacedfont (pdf_font_monospaced);
  16. //set margins
  17. $pdf ->setmargins (Pdf_margin_left, Pdf_margin_top, pdf_margin_right);
  18. //set Auto Page breaks
  19. $pdf ->setautopagebreak (TRUE, Pdf_margin_bottom);
  20. //set Image Scale factor
  21. $pdf ->setimagescale (Pdf_image_scale_ratio);
  22. //set some language-dependent strings
  23. $pdf ->setlanguagearray ($l);
  24. // ---------------------------------------------------------
  25. //Set Font
  26. $pdf ->setfont (' Times ', ' BI ', 20);
  27. //Add a page
  28. $pdf ->addpage ();
  29. //print a line using Cell ()
  30. $pdf ->cell (0, ten, ' Example 002 ', 1, 1, ' C ');
  31. // ---------------------------------------------------------
  32. //close and output PDF document
  33. $pdf ->output (' example_002.pdf ', ' I ');
  34. ?>

  6. $pdf ->setcreator (Pdf_creator);
  7. $pdf ->setauthor (' Nicola asuni ');
  8. $pdf ->settitle (' TCPDF Example 009 ');
  9. $pdf ->setsubject (' TCPDF Tutorial ');
  10. $pdf ->setkeywords (' TCPDF, PDF, example, Test, guide ');
  11. //Set default header data
  12. $pdf ->setheaderdata (Pdf_header_logo, Pdf_header_logo_width, Pdf_header_title, pdf_header_string);
  13. //Set header and footer fonts
  14. $pdf ->setheaderfont (Array (Pdf_font_name_main, ", Pdf_font_size_main));
  15. $pdf ->setfooterfont (Array (pdf_font_name_data, ", Pdf_font_size_data));
  16. //Set default monospaced font
  17. $pdf ->setdefaultmonospacedfont (pdf_font_monospaced);
  18. //set margins
