Snappy is a PHP5 library allowing thumbnail, snapshot or PDF generation from a url or a html page. It uses the excellent webkit-based wkhtmltopdf and wkhtmltoimage available on OSX, linux, windows.

You will have to download wkhtmltopdf 0.11.0 >= rc1 in order to use Snappy.

    "require" :  {
        "knplabs/knp-snappy": "*"
    }
}

Usage

<?php

require_once '/path/to/snappy/src/autoload.php';

use Knp\Snappy\Pdf;

$snappy = new Pdf('/usr/local/bin/wkhtmltopdf');

// or you can do it in two steps
$snappy = new Pdf();
$snappy->setBinary('/usr/local/bin/wkhtmltopdf');

// Display the resulting pdf in the browser
// by setting the Content-type header to pdf
$snappy = new Pdf('/usr/local/bin/wkhtmltopdf');
header('Content-Type: application/pdf');
header('Content-Disposition: attachment; filename="file.pdf"');
echo $snappy->getOutput('http://www.github.com');

// .. or simply save the PDF to a file
$snappy = new Pdf('/usr/local/bin/wkhtmltopdf');
$snappy->generateFromHtml('<h1>Bill</h1><p>You owe me money, dude.</p>', '/tmp/bill-123.pdf');

wkhtmltopdf binary as composer dependencies

If you want to download wkhtmltopdf with composer you add to composer.json:

{
    "require": {
        "google/wkhtmltopdf-i386": "0.11.0-RC1"
    }
}

or this if you are in 64 bit based system:

{
    "require": {
        "google/wkhtmltopdf-amd64": "0.11.0-RC1"
    }
}

NOTE: to be able to use those custom defined packages you need to copy into your composer.json following code:

{
    "repositories": [
        {
            "type": "package",
            "package": {
                "name": "google/wkhtmltopdf-amd64",
                "version": "0.11.0-RC1",
                "dist": {
                    "url": "http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.11.0_rc1-static-amd64.tar.bz2",
                    "type": "tar"
                }
            }
        },
        {
            "type": "package",
            "package": {
                "name": "google/wkhtmltopdf-i386",
                "version": "0.11.0-RC1",
                "dist": {
                    "url": "http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.11.0_rc1-static-i386.tar.bz2",
                    "type": "tar"
                }
            }
        }
    ]
}

And then you can use it

<?php

use Knp\Snappy\Pdf;

$myProjetDirectory = '/path/to/my/project';

$snappy = new Pdf($myProjetDirectory . '/vendor/google/wkhtmltopdf-i386/wkhtmltopdf-i386');

// or

$snappy = new Pdf($myProjetDirectory . '/vendor/google/wkhtmltopdf-amd64/wkhtmltopdf-amd64');
