Favicon Finder

Simple PHP library to work out the favicon for a site, given an URL.

It currently supports finding the default favicon, if it exists on the host (eg /favicon.ico) as well as some basic HTML parsing of the homepage to hunt for standard favicon tags. Does not support apple type icons or manifests, although it can be extended to do so if necessary (PRs welcome).

This library is based on Arthur Hoaro's work.

Here are the changes you can see in this version:

• Only return favicon paths, when found
• PSR-16: Simple Cache support
• More extensive HTML scraping tests
• PHP 7.3+ support

Requirements

• PHP 7.3
• php-xml extension: parse HTML content
• php-curl
• Guzzle
• GNU Make (or compatible): This is optional, if you want to contribute and use the Makefile targets available for running tests

Installation

composer req luispabon/favicon-finder

Basic usage

require_once('vendor/autoload.php');

$guzzle = new \GuzzleHttp\Client();

// You can use any PSR-16 implementation here - if you have none and don't care
// about caching, simply use the provided dummy cache implementation below
$cache = new \FaviconFinder\DummyCache();

// Cache lifetime in seconds (default is 86400 or 1 day)
$ttl = 60;

$favicon = new \FaviconFinder\Favicon($guzzle, $cache, $ttl);

echo $favicon->get('https://github.com/luispabon/favicon-finder');

// Displays: https://github.com/favicon.ico
var_dump($favicon->get('http://nofavicon.tld'));
// Returns null
