CrawlerDetect is a PHP class for detecting bots/crawlers/spiders via the user agent and http_from header. Currently able to detect 1,000's of bots/spiders/crawlers.
Run composer require jaybizzle/crawler-detect 1.* or add "jaybizzle/crawler-detect" :"1.*" to your composer.json.
use Jaybizzle\CrawlerDetect\CrawlerDetect;
$CrawlerDetect = new CrawlerDetect;
// Check the user agent of the current 'visitor'
if($CrawlerDetect->isCrawler()) {
// true if crawler user agent detected
}
// Pass a user agent as a string
if($CrawlerDetect->isCrawler('Mozilla/5.0 (compatible; Sosospider/2.0; +http://help.soso.com/webspider.htm)')) {
// true if crawler user agent detected
}
// Output the name of the bot that matched (if any)
echo $CrawlerDetect->getMatches();If you find a bot/spider/crawler user agent that CrawlerDetect fails to detect, please submit a pull request with the regex pattern added to the $data array in Fixtures/Crawlers.php and add the failing user agent to tests/crawlers.txt.
Failing that, just create an issue with the user agent you have found, and we'll take it from there :)
