Robots.txt

Robots.txt parser

Installation

composer require innmind/robots-txt

Usage

use Innmind\RobotsTxt\Parser;
use Innmind\OperatingSystem\Factory;
use Innmind\Url\Url;

$os = Factory::build();
$parse = Parser::of(
    $os->remote()->http(),
    'My user agent',
);
$robots = $parse(Url::of('https://github.com/robots.txt'))->match(
    static fn($robots) => $robots,
    static fn() => throw new \RuntimeException('robots.txt not found'),
);
$robots->disallows('My user agent', Url::of('/humans.txt')); //false
$robots->disallows('My user agent', Url::of('/any/other/url')); //true

Note

Here only the path /humans.txt is allowed because by default github disallows any user agent to crawl there website except for this file.
