Usage
First, you need to create a builder. With this builder you can create sections for different user agents and add the directives to it.
You can also add a header to the robots.txt and register your sitemap URLs.
Adding Sections
use Becklyn\RobotsTxt\Builder\RobotsTxtBuilder; $builder = new RobotsTxtBuilder(); // adding a section $builder->getSection("google") ->allow("/public") ->disallow("/admin") ->crawlDelay(20); $builder->getSection("bing") ->allow("/public") ->disallow("/admin") ->disallow("/private") ->crawlDelay(15);
If multiple search engines have the same directives, you can add one section for all of them:
$builder->getSection("google", "bing") ->allow("/public") ->disallow("/admin") ->crawlDelay(20);
The builder tries to bundle combine the directives of multiple sections if possible:
$builder->getSection("google") ->allow("/public"); // ... some code ... $builder->getSection("google") ->disallow("/admin") // will produce a single entry: // // User-Agent: google // Allow: /public // Disallow: /admin
Sitemaps
$builder ->addSitemap("https://example.org/sitemap.xml.tar.gz") ->addSitemap("https://example.org/sitemap.xml");
Header
You can also add a header which will be included at the very top:
$builder ->setHeader("This is some example text"); $builder->getSection("google") ->allow("/public"); // Will produce: // // # This is some example text // // User-Agent: google // Allow: /public
Outputting the robots.txt
$content = $builder->getFormatted(); file_put_contents("robots.txt", $content);
