Download the PHP package francerz/exfpdf without Composer

ExFPDF (Extended Free PDF)

This library extends basic functionality of the FPDF class.

FPDF is a PHP class which allows to generate PDF files with pure PHP. F from FPDF stands for Free: you may use it for any kind of usage and modify it to suit your needs.

Installation

The easiest and optimal way to install ExFPDF is by using Composer.

If you already using Composer, just run the next command and will be fully installed.

Extended functionality

Output result as PSR-7 ResponseInterface

The ExFPDF allows to output resultant PDF to PSR-7 compliant ResponseInterface object. Relies on PSR-17 Http Factories to create the instances.

Usage example

Alternative simplified method OutputPsr7WithManager

Alternatively you can use HttpFactoryManager to handle multiple factories instances to reduce parameters, improving reusability.

Usage example

Even simplier with in-home HTTP library

In the following example is used the simplified version with in-home HTTP library francerz/http wich is PSR-7, PSR-17 and PSR-18 compliant.

Relative Positioning and Sizing

Its allowed to use X, Y, Width and Height as percents of current page size.

Also the positioning and sizing can be relative to the page content area, inside the margins.

Therefore, you can get measure calculations with methods CalcX($x), CalcY($y), CalcWidth($w) and CalcHeight($h).

Offset positioning

Allows to increase or decrease current position.

Coordinate Pinning

It's posible to pin coordinates with a name.

Relative Cell Height based on Font Size

Define automatic line height size based on current Font Size.

Simplified content encoding

Allows internal decoding strings without writing on each cell.

Right aligned Cell

Puts a cell aligned to the right margin of the page. Optionally $margin can be set to displace the Cell from the right margin.

Header and Footer

Allows to define Header and Footer using anonymous functions.

• SetHeader(callable $headerFunc, $headerHeight = null)
  Sets a callable function that will execute when Header is loading. If parameter $headerHeight is null, then will be calculated and body content will be displaced. If is set, then content will be displaced $headerHeight plus the top margin.
• SetFooter(callable $footerFunc, $footerHeight = null)
  Sets a callable function that will execute when Footer is loading. If parameter $footerHeight is null, then will be calculated and page break will executed before reaching footer content. If is set, the footer will be displaced from based on page bottom edge.

Note:
It's important to invoke SetHeader() and SetFooter() before AddPage().

Tables

Table PDF creation is simplified and with automatic overflowing when cells overflows in multiple pages.

Barcode support

Using the barcode128 puts the given $code ASCII string at the given $x and $y position. And with given $w (width) and $h (height). This measures are compatible with the relative positioning and sizing.

If no $x or $y is set, then will be the current PDF position.

Using the barcode39 puts the given $code ([-0-9A-Z. *$/+%]) string at the given $x and $y position, with the given $w (width) and $h (height). This meaures are compatible with the relative positioning and sizing.

QR and DataMatrix support
