README

A light-weight library for extracting meta tags from URL or HTML content.

It allows you to:

• get all meta tags from URL or HTML content (including title, charset, and html[lang] attribute),
• set custom cache provider for caching the results of web scraping (using PSR-16 Psr\SimpleCache\CacheInterface),
• set custom HTTP client for web scraping (using PSR-18 Psr\Http\Client\ClientInterface),

This library can be considered as an extended alternative for get_meta_tags() function.

Requirements

• PHP 8.1 or higher
• PHP DOM extension

Installation

composer require martinille/meta-tag-extraction

Usage

use MartinIlle\MetaTagExtraction\MetaTagExtraction;

$url = 'https://example.com';
$metaTagExtraction = new MetaTagExtraction();

$metaTags = $metaTagExtraction->extractFromUrl($url);

foreach ($metaTags as $tag) {
	echo $tag->getName() . ': ' . $tag->getValue() . PHP_EOL;
}
/* output:
charset: utf-8
content-type: text/html; charset=utf-8
viewport: width=device-width, initial-scale=1
title: Example Domain
*/
