I was wondering if there was any documentation or any new libraries which can detect the new iPadOS / iOS 13?
They used to output:
mozilla/5.0 (ipad; cpu iphone os 12_1_3 like mac os x) applewebkit/605.1.15 (khtml, like gecko) version/12.0 mobile/15e148 safari/604.1
But are now outputting:
mozilla/5.0 (macintosh; intel mac os x 10_15) applewebkit/605.1.15 (khtml, like gecko) version/13.0.1 safari/605.1.15
Has anyone come across this? Any new libraries to use?
Best I got as a solution was to use javascript:
// iPad check
if( (window.screen.height / window.screen.width == 1024 / 768) ||
(window.screen.height / window.screen.width == 1112 / 834) ||
(window.screen.height / window.screen.width == 1366 / 1024)
) {
// do stuff here
}
Not as perviously intended, but the best solution I have.
couldn't figure out a php way of doing it, but with javascript this seems to be the most appropriate yet
First detect if device is a mobile one. In recent iOS for iPad, this check returns false, which is practically wrong, but that's due to a desktop user agent.
Second test if the device has touch properties and see if platform contains the 'MacIntel' string
let isMobile = /iPhone|iPad|iPod|Android/i.test(navigator.userAgent);
let isIOSMobile = navigator.platform === 'MacIntel' && navigator.maxTouchPoints > 1;
if (!isMobile && isIOSMobile ) {
//Desktop mode on IPad detected
alert("For the best experience we recommend switching Safari view to mobile");
}
This is a php solution and it works fine for me:
<?php
//Detect special conditions devices
$iPod = stripos($_SERVER['HTTP_USER_AGENT'],"iPod");
$iPhone = stripos($_SERVER['HTTP_USER_AGENT'],"iPhone");
$iPad = stripos($_SERVER['HTTP_USER_AGENT'],"iPad");
$iPadOS = stripos($_SERVER['HTTP_USER_AGENT'],"Macintosh");
$Android = stripos($_SERVER['HTTP_USER_AGENT'],"Android");
//TODO
if( $iPod || $iPhone || $iPad || $iPadOS || $Android){
//your methods
}
How can one detect the search engine bots using php?
I use the following code which seems to be working fine:
function _bot_detected() {
return (
isset($_SERVER['HTTP_USER_AGENT'])
&& preg_match('/bot|crawl|slurp|spider|mediapartners/i', $_SERVER['HTTP_USER_AGENT'])
);
}

added mediapartners
Here's a Search Engine Directory of Spider names
Then you use $_SERVER['HTTP_USER_AGENT']; to check if the agent is said spider.
if(strstr(strtolower($_SERVER['HTTP_USER_AGENT']), "googlebot"))
{
// what to do
}
Check the $_SERVER['HTTP_USER_AGENT'] for some of the strings listed here:
http://www.useragentstring.com/pages/useragentstring.php
Or more specifically for crawlers:
http://www.useragentstring.com/pages/useragentstring.php?typ=Crawler
If you want to -say- log the number of visits of most common search engine crawlers, you could use
$interestingCrawlers = array( 'google', 'yahoo' );
$pattern = '/(' . implode('|', $interestingCrawlers) .')/';
$matches = array();
$numMatches = preg_match($pattern, strtolower($_SERVER['HTTP_USER_AGENT']), $matches, 'i');
if($numMatches > 0) // Found a match
{
// $matches[1] contains an array of all text matches to either 'google' or 'yahoo'
}
You can checkout if it's a search engine with this function :
<?php
function crawlerDetect($USER_AGENT)
{
$crawlers = array(
'Google' => 'Google',
'MSN' => 'msnbot',
'Rambler' => 'Rambler',
'Yahoo' => 'Yahoo',
'AbachoBOT' => 'AbachoBOT',
'accoona' => 'Accoona',
'AcoiRobot' => 'AcoiRobot',
'ASPSeek' => 'ASPSeek',
'CrocCrawler' => 'CrocCrawler',
'Dumbot' => 'Dumbot',
'FAST-WebCrawler' => 'FAST-WebCrawler',
'GeonaBot' => 'GeonaBot',
'Gigabot' => 'Gigabot',
'Lycos spider' => 'Lycos',
'MSRBOT' => 'MSRBOT',
'Altavista robot' => 'Scooter',
'AltaVista robot' => 'Altavista',
'ID-Search Bot' => 'IDBot',
'eStyle Bot' => 'eStyle',
'Scrubby robot' => 'Scrubby',
'Facebook' => 'facebookexternalhit',
);
// to get crawlers string used in function uncomment it
// it is better to save it in string than use implode every time
// global $crawlers
$crawlers_agents = implode('|',$crawlers);
if (strpos($crawlers_agents, $USER_AGENT) === false)
return false;
else {
return TRUE;
}
}
?>
Then you can use it like :
<?php $USER_AGENT = $_SERVER['HTTP_USER_AGENT'];
if(crawlerDetect($USER_AGENT)) return "no need to lang redirection";?>
I'm using this to detect bots:
if (preg_match('/bot|crawl|curl|dataprovider|search|get|spider|find|java|majesticsEO|google|yahoo|teoma|contaxe|yandex|libwww-perl|facebookexternalhit/i', $_SERVER['HTTP_USER_AGENT'])) {
// is bot
}
In addition I use a whitelist to block unwanted bots:
if (preg_match('/apple|baidu|bingbot|facebookexternalhit|googlebot|-google|ia_archiver|msnbot|naverbot|pingdom|seznambot|slurp|teoma|twitter|yandex|yeti/i', $_SERVER['HTTP_USER_AGENT'])) {
// allowed bot
}
An unwanted bot (= false-positive user) is then able to solve a captcha to unblock himself for 24 hours. And as no one solves this captcha, I know it does not produce false-positives. So the bot detection seem to work perfectly.
Note: My whitelist is based on Facebooks robots.txt.
Because any client can set the user-agent to what they want, looking for 'Googlebot', 'bingbot' etc is only half the job.
The 2nd part is verifying the client's IP. In the old days this required maintaining IP lists. All the lists you find online are outdated. The top search engines officially support verification through DNS, as explained by Google https://support.google.com/webmasters/answer/80553 and Bing http://www.bing.com/webmaster/help/how-to-verify-bingbot-3905dc26
At first perform a reverse DNS lookup of the client IP. For Google this brings a host name under googlebot.com, for Bing it's under search.msn.com. Then, because someone could set such a reverse DNS on his IP, you need to verify with a forward DNS lookup on that hostname. If the resulting IP is the same as the one of the site's visitor, you're sure it's a crawler from that search engine.
I've written a library in Java that performs these checks for you. Feel free to port it to PHP. It's on GitHub: https://github.com/optimaize/webcrawler-verifier
If you really need to detect GOOGLE engine bots you should never rely on "user_agent" or "IP" address because "user_agent" can be changed and acording to what google said in: Verifying Googlebot
To verify Googlebot as the caller:
1.Run a reverse DNS lookup on the accessing IP address from your logs, using the host command.
2.Verify that the domain name is in either googlebot.com or google.com
3.Run a forward DNS lookup on the domain name retrieved in step 1 using the host command on the retrieved domain name. Verify that it is the same as the original accessing IP address from your logs.
Here is my tested code :
<?php
$remote_add=$_SERVER['REMOTE_ADDR'];
$hostname = gethostbyaddr($remote_add);
$googlebot = 'googlebot.com';
$google = 'google.com';
if (stripos(strrev($hostname), strrev($googlebot)) === 0 or stripos(strrev($hostname),strrev($google)) === 0 )
{
//add your code
}
?>
In this code we check "hostname" which should contain "googlebot.com" or "google.com" at the end of "hostname" which is really important to check exact domain not subdomain.
I hope you enjoy ;)
I use this function ... part of the regex comes from prestashop but I added some more bot to it.
public function isBot()

$bot_regex = '/BotLink|bingbot|AhrefsBot|ahoy|AlkalineBOT|anthill|appie|arale|araneo|AraybOt|ariadne|arks|ATN_Worldwide|Atomz|bbot|Bjaaland|Ukonline|borg\-bot\/0\.9|boxseabot|bspider|calif|christcrawler|CMC\/0\.01|combine|confuzzledbot|CoolBot|cosmos|Internet Cruiser Robot|cusco|cyberspyder|cydralspider|desertrealm, desert realm|digger|DIIbot|grabber|downloadexpress|DragonBot|dwcp|ecollector|ebiness|elfinbot|esculapio|esther|fastcrawler|FDSE|FELIX IDE|ESI|fido|H�m�h�kki|KIT\-Fireball|fouineur|Freecrawl|gammaSpider|gazz|gcreep|golem|googlebot|griffon|Gromit|gulliver|gulper|hambot|havIndex|hotwired|htdig|iajabot|INGRID\/0\.1|Informant|InfoSpiders|inspectorwww|irobot|Iron33|JBot|jcrawler|Teoma|Jeeves|jobo|image\.kapsi\.net|KDD\-Explorer|ko_yappo_robot|label\-grabber|larbin|legs|Linkidator|linkwalker|Lockon|logo_gif_crawler|marvin|mattie|mediafox|MerzScope|NEC\-MeshExplorer|MindCrawler|udmsearch|moget|Motor|msnbot|muncher|muninn|MuscatFerret|MwdSearch|sharp\-info\-agent|WebMechanic|NetScoop|newscan\-online|ObjectsSearch|Occam|Orbsearch\/1\.0|packrat|pageboy|ParaSite|patric|pegasus|perlcrawler|phpdig|piltdownman|Pimptrain|pjspider|PlumtreeWebAccessor|PortalBSpider|psbot|Getterrobo\-Plus|Raven|RHCS|RixBot|roadrunner|Robbie|robi|RoboCrawl|robofox|Scooter|Search\-AU|searchprocess|Senrigan|Shagseeker|sift|SimBot|Site Valet|skymob|SLCrawler\/2\.0|slurp|ESI|snooper|solbot|speedy|spider_monkey|SpiderBot\/1\.0|spiderline|nil|suke|http:\/\/www\.sygol\.com|tach_bw|TechBOT|templeton|titin|topiclink|UdmSearch|urlck|Valkyrie libwww\-perl|verticrawl|Victoria|void\-bot|Voyager|VWbot_K|crawlpaper|wapspider|WebBandit\/1\.0|webcatcher|T\-H\-U\-N\-D\-E\-R\-S\-T\-O\-N\-E|WebMoose|webquest|webreaper|webs|webspider|WebWalker|wget|winona|whowhere|wlm|WOLP|WWWC|none|XGET|Nederland\.zoek|AISearchBot|woriobot|NetSeer|Nutch|YandexBot|YandexMobileBot|SemrushBot|FatBot|MJ12bot|DotBot|AddThis|baiduspider|SeznamBot|mod_pagespeed|CCBot|openstat.ru\/Bot|m2e/i';
$userAgent = empty($_SERVER['HTTP_USER_AGENT']) ? FALSE : $_SERVER['HTTP_USER_AGENT'];
$isBot = !$userAgent || preg_match($bot_regex, $userAgent);
return $isBot;
}
Anyway take care that some bots uses browser like user agent to fake their identity
( I got many russian ip that has this behaviour on my site )
One distinctive feature of most of the bot is that they don't carry any cookie and so no session is attached to them.
( I am not sure how but this is for sure the best way to track them )
Use Device Detector open source library, it offers a isBot() function: https://github.com/piwik/device-detector
You could analyse the user agent ($_SERVER['HTTP_USER_AGENT']) or compare the client’s IP address ($_SERVER['REMOTE_ADDR']) with a list of IP addresses of search engine bots.
I made one good and fast function for this
function is_bot(){
if(isset($_SERVER['HTTP_USER_AGENT']))
{
return preg_match('/rambler|abacho|acoi|accona|aspseek|altavista|estyle|scrubby|lycos|geona|ia_archiver|alexa|sogou|skype|facebook|twitter|pinterest|linkedin|naver|bing|google|yahoo|duckduckgo|yandex|baidu|teoma|xing|java\/1.7.0_45|bot|crawl|slurp|spider|mediapartners|\sask\s|\saol\s/i', $_SERVER['HTTP_USER_AGENT']);
}
return false;
}
This cover 99% of all possible bots, search engines etc.

That would be the ideal way to cloak for spiders. It's from an open source script called [YACG] - http://getyacg.com
Needs a bit of work, but definitely the way to go.

I'm using this code, pretty good. You will very easy to know user-agents visitted your site. This code is opening a file and write the user_agent down the file. You can check each day this file by go to yourdomain.com/useragent.txt and know about new user_agents and put them in your condition of if clause.
$user_agent = strtolower($_SERVER['HTTP_USER_AGENT']);
if(!preg_match("/Googlebot|MJ12bot|yandexbot/i", $user_agent)){
// if not meet the conditions then
// do what you need
// here open a file and write the user_agent down the file. You can check each day this file useragent.txt and know about new user_agents and put them in your condition of if clause
if($user_agent!=""){
$myfile = fopen("useragent.txt", "a") or die("Unable to open file useragent.txt!");
fwrite($myfile, $user_agent);
$user_agent = "\n";
fwrite($myfile, $user_agent);
fclose($myfile);
}
}
This is the content of useragent.txt

Verifying Googlebot
As useragent can be changed...
the only official supported way to identify a google bot is to run a
reverse DNS lookup on the accessing IP address and run a forward DNS
lookup on the result to verify that it points to accessing IP address
and the resulting domain name is in either googlebot.com or google.com
domain.
Taken from here.
so you must run a DNS lookup
Both, reverse and forward.
See this guide on Google Search Central.
function bot_detected() {
if(preg_match('/bot|crawl|slurp|spider|mediapartners/i', $_SERVER['HTTP_USER_AGENT']){
return true;
}
else{
return false;
}
}
might be late, but what about a hidden a link. All bots will use the rel attribute follow, only bad bots will use the nofollow rel attribute.
<a style="display:none;" rel="follow" href="javascript:void(0);" onclick="isabot();">.</a>
function isabot(){
//define a variable to pass with ajax to php
// || send bots info direct to where ever.
isabot = true;
}
for a bad bot you can use this:
<a style="display:none;" href="javascript:void(0);" rel="nofollow" onclick="isBadbot();">.</a>
for PHP specific you can remove the onclick attribute and replace the href attribute with a link to your ip detector/ bot detector like so:
<a style="display:none;" rel="follow" href="https://somedomain.com/botdetector.php">.</a>
OR
<a style="display:none;" rel="nofollow" href="https://somedomain.com/badbotdetector.php">.</a>
you can work with it and maybe use both, one detects a bot, while the other proves it to be a bad bot.
hope you find this useful
Hi Im tracking the browsers of the users who are visiting my site with the use of browsecap.ini
the following is the code that i use
if(isset($message['HTTP_USER_AGENT'])){
$get_browser = get_browser($message['HTTP_USER_AGENT'], true);
if (!empty($get_browser)){
$str_values.='".mysql_real_escape_string($get_browser['comment'])."'
But when the users who use the opera browser in a galaxy tab are shown as chrome browser users
can anybody help me to rectify this isse
P.S - Im using the lite version of browsecap.ini file
You kindly provided me with a sample UA string of the offending mobile Opera browser:
Mozilla/5.0 (Linux; Android 4.1.2; GT-P3100 Build/JZO54K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.81 Safari/537.36 OPR/28.0.1764.90386
and the regex returned by get_browser() on that UA is:
$^mozilla/5.0 (.*linux.android.4.1.) applewebkit/.* (khtml, like gecko).*chrome/41..safari/.$
which didn't detect the Opera browser at all. However, I found this function that you can also run to get the browser name. The very first check is for that "OPR/" fragment of the UA string.
When run with the test UA supplied above, the output is "Opera".
<?php
function ExactBrowserName() {
$ExactBrowserNameUA=$_SERVER['HTTP_USER_AGENT'];
If (strpos(strtolower($ExactBrowserNameUA), "safari/") and strpos(strtolower($ExactBrowserNameUA), "opr/")) {
// OPERA
$ExactBrowserNameBR="Opera";
} ElseIf (strpos(strtolower($ExactBrowserNameUA), "safari/") and strpos(strtolower($ExactBrowserNameUA), "chrome/")) {
// CHROME
$ExactBrowserNameBR="Chrome";
} ElseIf (strpos(strtolower($ExactBrowserNameUA), "msie")) {
// INTERNET EXPLORER
$ExactBrowserNameBR="Internet Explorer";
} ElseIf (strpos(strtolower($ExactBrowserNameUA), "firefox/")) {
// FIREFOX
$ExactBrowserNameBR="Firefox";
} ElseIf (strpos(strtolower($ExactBrowserNameUA), "safari/") and strpos(strtolower($ExactBrowserNameUA), "opr/")==false and strpos(strtolower($ExactBrowserNameUA), "chrome/")==false) {
// SAFARI
$ExactBrowserNameBR="Safari";
} Else {
// OUT OF DATA
$ExactBrowserNameBR="OUT OF DATA";
};
return $ExactBrowserNameBR;
}
?>

It works on facebook. But when I want to get my page speed results with google, i get "Sorry, we can only serve to Azerbaijan!" error
This is the one of the user agent of Google Page Speed Insight
Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko; Google Page Speed Insights) Chrome/27.0.1453 Safari/537.36
Change this
!preg_match("/Googlebot/", $agent)
to this
!preg_match("/Google(bot| Page Speed Insights)/", $agent)
I use below code to find user agent,
$user_agent = $_SERVER['HTTP_USER_AGENT'];
if (preg_match('/MSIE/i', $user_agent)) {
echo "Internet Explorer";
}
if (preg_match('/Firefox/i', $user_agent)) {
echo "FireFox";
}
if (strpos( $user_agent, 'Chrome') !== false)
{
echo "Google Chrome";
}
if (strpos( $user_agent, 'Safari') !== false)
{
echo "Safari";
}
if (preg_match('/Opera/i', $user_agent)) {
echo "Opera";
}
?>
But my chrome browser returning below useragent suddenly
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_4) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.155 Safari/537.22
It contains the word safari and chrome.so both the browser names are printed.what is the solution for this.thanks.
Chrome's user agent contains Safari but Safari's user agent doesn't contain Chrome so use if ... elseif:
if (stripos( $user_agent, 'Chrome') !== false)
{
echo "Google Chrome";
}
elseif (stripos( $user_agent, 'Safari') !== false)
{
echo "Safari";
}
Note: use stripos instead of strpos to account for case-variations.
Try this :
$browser = get_browser(null, true);
print_r($browser);
From doc : Attempts to determine the capabilities of the user's browser, by looking up the browser's information in the browscap.ini file.
