PHP Html Parser

Version 1.6.1

PHPHtmlParser is a simple, flexible, html parser which allows you to select tags using any css selector, like jQuery. The goal is to assiste in the development of tools which require a quick, easy way to scrap html, whether it's valid or not! This project was original supported by sunra/php-simple-html-dom-parser but the support seems to have stopped so this project is my adaptation of his previous work.

Install

This package can be found on packagist and is best loaded using composer. It does require php 5.4 or higher, so keep that in consideration.

Usage

You can find many examples of how to use the dom parser and any of its parts (which you will most likely never touch) in the tests directory. The tests are done using PHPUnit and are very small, a few lines each, and are a great place to start. Given that, I'll still be showing a few examples of how the package should be used. The following example is a very simplistic usage of the package.

use PHPHtmlParser\Dom;

$dom = new Dom;
$dom->load('<div class="all"><p>Hey bro, <a href="google.com">click here</a><br /> :)</p></div>');
$a = $dom->find('a')[0];
echo $a->text; // "click here"

The above will output "click here". Simple no? There are many ways to get the same result from the dome, such as $dom->getElementsbyTag('a')[0] or $dom->find('a', 0) which can all be found in the tests or in the code itself.

Example With Files

You may also seamlessly load a file into the dom instead of a string, which is much more convinient and is how I except most developers will be loading the html. The following example is taken from our test and uses the "big.html" file found there.

use PHPHtmlParser\Dom;

$dom = new Dom;
$dom->loadFromFile('tests/big.html');
$contents = $dom->find('.content-border');
echo count($contents); // 10

foreach ($contents as $content)
{
	// get the class attr
	$class = $content->getAttribute('class');
	
	// do something with the html
	$html = $content->innerHtml;

	// or refine the find some more
	$child   = $content->firstChild();
	$sibling = $child->nextSibling();
}

This example loads the html from big.html, a real page found online, and gets all the content-border classes to process. It also shows a few things you can do with a node but it is not an exhaustive list of methods that a node has avaiable.

Alternativly, you can always use the load() method to load the file. It will attempt to find the file using file_exists and, if succesfull, will call loadFromFile() for you. The same applies to a URL and loadFromUrl() method.

Static Facade

You can also mount a static facade for the Dom object.

PHPHtmlParser\StaticDom::mount();

Dom::load('tests/big.hmtl');
$objects = Dom::find('.content-border');

The above php block does the same find and load as the first example but it is done using the static facade, which supports all public methods found in the Dom object.
