Create and modify PDF documents using PHP _php tutorial

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

 
 

  
  

  
 
  
  

  

  
  

  
require_once ('.. /config/lang/eng.php '); 
  
  

  
require_once ('.. /tcpdf.php '); 
  
  

  

  
  

  
//Create new PDF document  
  
  

  
$pdf  =  New TCPDF (pdf_page_orientation, Pdf_unit, Pdf_page_format, True,  ' UTF-8 ', false); 
  
  

  

  
  

  
//Set Document information  
  
  

  
$pdf ->setcreator (Pdf_creator); 
  
  

  
$pdf ->setauthor (' Nicola asuni '); 
  
  

  
$pdf ->settitle (' TCPDF Example 002 '); 
  
  

  
$pdf ->setsubject (' TCPDF Tutorial '); 
  
  

  
$pdf ->setkeywords (' TCPDF, PDF, example, Test, guide '); 
  
  

  

  
  

  
//Remove default Header/footer  
  
  

  
$pdf ->setprintheader (FALSE); 
  
  

  
$pdf ->setprintfooter (FALSE); 
  
  

  

  
  

  
//Set default monospaced font  
  
  

  
$pdf ->setdefaultmonospacedfont (pdf_font_monospaced); 
  
  

  

  
  

  
//set margins  
  
  

  
$pdf ->setmargins (Pdf_margin_left, Pdf_margin_top, pdf_margin_right); 
  
  

  

  
  

  
//set Auto Page breaks  
  
  

  
$pdf ->setautopagebreak (TRUE, Pdf_margin_bottom); 
  
  

  

  
  

  
//set Image Scale factor  
  
  

  
$pdf ->setimagescale (Pdf_image_scale_ratio); 
  
  

  

  
  

  
//set some language-dependent strings  
  
  

  
$pdf ->setlanguagearray ($l); 
  
  

  

  
  

  
// ---------------------------------------------------------   
  
  

  

  
  

  
//Set Font  
  
  

  
$pdf ->setfont (' Times ',  ' BI ', 20); 
  
  

  

  
  

  
//Add a page  
  
  

  
$pdf ->addpage (); 
  
  

  

  
  

  
//print a line using Cell ()  
  
  

  
$pdf ->cell (0, ten,  ' Example 002 ', 1, 1,  ' C '); 
  
  

  

  
  

  
// ---------------------------------------------------------   
  
  

  

  
  

  
//close and output PDF document  
  
  

  
$pdf ->output (' example_002.pdf ',  ' I '); 
  
  

  
?>
 
 

Using PHP to modify PDF documents

Here we discuss how to modify PDF documents using PHP. Suppose we need to add a picture to the PDF via a PHP program, the sample code is as follows:

Example two: Adding a picture to a PDF using PHP

 
 

  
  

  
 
  
  

  
require_once ('.. /config/lang/eng.php '); 
  
  

  
require_once ('.. /tcpdf.php '); 
  
  

  

  
  

  
//Create new PDF document  
  
  

  
$pdf  =  New TCPDF (pdf_page_orientation, Pdf_unit, Pdf_page_format, True,  ' UTF-8 ', false); 
  
  

  

  
  

  
//Set Document information  
  
  

  
$pdf ->setcreator (Pdf_creator); 
  
  

  
$pdf ->setauthor (' Nicola asuni '); 
  
  

  
$pdf ->settitle (' TCPDF Example 009 '); 
  
  

  
$pdf ->setsubject (' TCPDF Tutorial '); 
  
  

  
$pdf ->setkeywords (' TCPDF, PDF, example, Test, guide '); 
  
  

  

  
  

  
//Set default header data  
  
  

  
$pdf ->setheaderdata (Pdf_header_logo, Pdf_header_logo_width, Pdf_header_title, pdf_header_string); 
  
  

  

  
  

  
//Set header and footer fonts  
  
  

  
$pdf ->setheaderfont (Array (Pdf_font_name_main,  ", Pdf_font_size_main)); 
  
  

  
$pdf ->setfooterfont (Array (pdf_font_name_data,  ", Pdf_font_size_data)); 
  
  

  

  
  

  
//Set default monospaced font  
  
  

  
$pdf ->setdefaultmonospacedfont (pdf_font_monospaced); 
  
  

  

  
  

  
//set margins  
  
  

  
$pdf ->setmargins (Pdf_margin_left, Pdf_margin_top, pdf_margin_right); 
  
  

  
$pdf ->setheadermargin (Pdf_margin_header); 
  
  

  
$pdf ->setfootermargin (Pdf_margin_footer); 
  
  

  

  
  

  
//set Auto Page breaks  
  
  

  
$pdf ->setautopagebreak (TRUE, Pdf_margin_bottom); 
  
  

  

  
  

  
//set Image Scale factor  
  
  

  
$pdf ->setimagescale (Pdf_image_scale_ratio); 
  
  

  

  
  

  
//set some language-dependent strings  
  
  

  
$pdf ->setlanguagearray ($l); 
  
  

  

  
  

  
// ---------------------------------------------------------   
  
  

  

  
  

  
//Add a page  
  
  

  
$pdf ->addpage (); 
  
  

  

  
  

  
//Set JPEG quality  
  
  

  
$pdf ->setjpegquality (75); 
  
  

  

  
  

  
//Image Example  
  
  

  
$pdf ->image ('.. /images/image_demo.jpg ',   ', ', ', ', ', ', ', ' http://www.tcpdf.org',  ", True, 150); 
  
  

  

  
  

  
// ---------------------------------------------------------   
  
  

  

  
  

  
//close and output PDF document  
  
  

  
$pdf ->output (' example_009.pdf ',  ' I '); 
  
  

  
?>
