Robots Exclusion Protocol Checking Classes v1.0.4

These classes allow you to check all of the different ways you can exclude a URL from search engines.

Classes

You can instantiate the following classes:

• NickMoline\Robots\RobotsTxt : Checks the corresponding robots.txt file for a url
• NickMoline\Robots\Status : Checks the HTTP Status code for an indexable URL
• NickMoline\Robots\Header : Checks the HTTP X-Robots-Tag Header
• NickMoline\Robots\Meta : Checks the <meta name="robots"> tag (as well as bot specific tags)
• NickMoline\Robots\All : Wrapper class that will run all of the above checks

Example Usage

<?php

require NickMoline\Robots\RobotsTxt;
require NickMoline\Robots\Header as RobotsHeader;
require NickMoline\Robots\All as RobotsAll;

$checker = new RobotsTxt("http://www.example.com/test.html");
$allowed = $checker->verify();                              // By default it checks Googlebot
$allowed = $checker->setUserAgent("bingbot")->verify();     // Checks to see if blocked for bingbot by robots.txt file

echo $checker->getReason();              // Get the reason the url is allowed or denied

$checker2 = new RobotsHeader("http://www.example.com/test.html");
$allowed = $checker->verify();           // Same as above but will test the X-Robots-Tag HTTP headers

$checkerAll = new RobotsAll("http://www.example.com/test.html");
$allowed = $checker->verify();           // This one runs all of the available tests
