# Chrome version shows 0.0

 * Hey Folks,
 * With Chrome Browser, PHP Browser Detection plugin (Version 3.1.3) is now reporting
   the version of Chrome as “0.0”. It correctly reports the browser to be Chrome,
   but the version is always showing 0.0.
 * Other browsers are reporting their versions correctly. I’ve tried with Firefox,
   Safari and IE; all report version correctly.
 * I’ve tried on multiple different computers and devices with the same results.
   I’ve tried with the plugin installed on different websites with the same results.
   I’ve tried it on a sandbox development website with basically nothing else installed
   and get the same problem there:
    sandbox.insitewebsite.com
 * (The first line of text in the site there should report browser and version.)
 * When I previously inquired about ALL browsers reporting version as 0.0, you advised
   to uninstall and re-install PHP Browser Detection plugin. I’ve done that but 
   the problem persists.
 * Any ideas what might be going on?
 * Thanks!

 * Thanks for letting us know. We’ll publish an update ASAP, the browscap.ini file
   needs to be updated.

 * Thanks a lot! I appreciate it!
 * This is a little out of my league, but for curiosity’s sake, I’m wondering if
   there might not be some way to avoid the need for you folks to periodically check
   and manually update browsercap.ini?
 * Might it be possible for the plugin to contain some kind of script that would
   periodically check for an updated brosercap.ini file and replace it with a newer
   one if it is available? Something along the lines of this perhaps?

 * I’m sure that you can rattle off a dozen reasons why that is not possible, so
   excuse my naivete, but I’m simply curious…

 * Yes we used to have this feature enabled but had to disable it because so many
   users of the plugin are on shared hosting that does not have enough memory to
   update and cache the browscap.ini file (it is quite large). So in order to prevent
   out of memory errors we removed it. It’s on the roadmap to add a way to manually
   enable it.

 * I understand; thanks!
 * So with your current manual method, do you update the plugin every time there
   is a new version of browscap.ini (how often is that?) or only when it has changed
   enough that it is no longer working to do the things your plugin requires?
 * And a related question (if you don’t mind?):
    Do you use the standard, full or
   lite version of browscap.ini? What is the difference, in a nutshell, between 
   php_browscap.ini and lite_php_browscap.ini ? What _doesn’t_ the lite version 
   do? (Or, if you use the full version, what doesn’t the standard version do?)

 * 1. We’ve been relying on user to let us know when there’s a problem (not ideal)
 * 2. Full PHP version, lite doesn’t provide many of the fields for each user agent
   and doesn’t include many mobile devices.
 * We’ll enable some new options to address the update issue in the next release.

 * Thanks for those answers.
 * Re 1. I’m happy to report problems when I notice them. (But yes, not ideal. Great
   to hear that you’re looking into options.)
 * Re 2. OK, if you’re using the full version of browscap.ini, what does the standard
   version _not_ provide that the full version does? (It is half the size.)
 * I’ve searched around for info on the different versions but I was only able to
   find this kinda ‘work in progress’ item:
    [https://github.com/browscap/browscap/wiki/Proposal—re-arrange-files-for-efficiency](https://github.com/browscap/browscap/wiki/Proposal—re-arrange-files-for-efficiency)
   I’m not sure if that is what ended up in the different versions.
 * Perhaps there could be an option to use a choice of versions? (Easy for me to
   say!!)

 * (Two months later…)
 * Once again, with Chrome Browser, PHP Browser Detection plugin (now version 3.1.4)
   is reporting the version of Chrome as “0.0”.
 * Time to update browsercap.ini file again?
 * Just wondering… have you gotten any further on alternatives to the “wait for 
   someone to report the problem, then update file” system? As previously, I’m happy
   to report this problem but it’s not an ideal solution…
 * Thanks much!

 * [@hommealone](https://wordpress.org/support/users/hommealone/), here are two 
   alternatives…
 * 1. you can always update the browscap.ini manually yourself by downloading and
   replacing it… [http://browscap.org/stream?q=PHP_BrowscapINI](http://browscap.org/stream?q=PHP_BrowscapINI)
 * 2. or just turn on the auto-update switch in /inc/Browscap.php
    `$doautoUpdate
   = true;` and adjust the update interval… `$updateInterval = 432000;`
 * as the existing update functions are still in place, just turned off.
 * as for improving the plugin itself, I think that there could be filters on these
   values so they can be set from outside the class and persist between plugin updates.
   eg:
    `$doAutoUpdate = apply_filters('browsercap_updates',false);` `$updateInterval
   = apply_filters('browsercap_update_interval',2592000);`
 * and make note of these in the readme.txt, rather than adding a UI just for them
   which is probably not necessary.
 * thanks for a great plugin by the way. 🙂

 * [10 years, 9 months ago](https://wordpress.org/support/topic/chrome-version-shows-00/#post-6127900)
 * oh yeah and a filter for `$remoteIniUrl` as well, so the “full” version could
   be used instead if that is wanted. heck, why not add filters to all the config
   variables just for the heck of it, lol.

 * [10 years, 9 months ago](https://wordpress.org/support/topic/chrome-version-shows-00/#post-6127901)
 * actually on further thought you can’t do option 1 above just like that, as the
   cache.php needs to be updated from the new browscap.ini… does not seem that easy
   to trigger… I have:
 *     ```
       global $browscap;
       $browscap->localFile = WP_PLUGIN_DIR.'/php-browser-detection/cache/php_browscap.ini';
       $browscap->updateCache();
       exit;
       ```
   
 * but it crashes at this line (of all places?) in _getRemoteIniFile
    `$browscap
   = explode("\n", $browscap);`
 * perhaps this is the memory usage issue talked about..? it is a rather big file
   to split like that. so I’d like to propose some alternatives…
 * 1. use substr instead of explode… as content variable gets bigger, browscap variable
   gets smaller the, saving memory…
 *     ```
       // $browscap = explode("\n", $browscap);
   
       $pattern  = self::REGEX_DELIMITER . '(' . self::VALUES_TO_QUOTE . ')="?([^"]*)"?$' . self::REGEX_DELIMITER;
   
       if (strstr($browscap,"\n")) {
       	while (strstr($browscap,"\n")) {
       		$pos = strpos($browscap,"\n");
       		$subject = trim(substr($browscap,0,$pos));
       		$content .= preg_replace($pattern, '$1="$2"', $subject)."\n";
       		$browscap = substr($browscap,($pos+1));
       	}
       	if ($browscap != '') {
       		$subject = trim($browscap);
       		$content .= preg_replace($pattern, '$1="$2"', $subject)."\n";
       	}
       } else {throw new Exception("No lines found.");}
       ```
   
 * 2. change the _getRemoteData function to write the file contents to a file, and
   then use fgets on the local file to retrieve it line by line…
 *     ```
       $pattern  = self::REGEX_DELIMITER . '(' . self::VALUES_TO_QUOTE . ')="?([^"]*)"?$' . self::REGEX_DELIMITER;
       $content = '';
       $fh = fopen($url,'r');
       while (!feof($fh)) {
       	$subject = trim(fgets($fh));
       	$content .= preg_replace($pattern, '$1="$2"', $subject) . "\n";
       }
       if (!file_put_contents($path, $content)) {
       	throw new Exception("Could not write .ini content to $path");
       }
       ```
   
 * the first example seems rather slow, but it does finish eventually. the second
   seems much faster but I’m not totally sure if the end result is the same or not(
   and again only works for local file source at the moment.)
 * either way I’m stuck here for now… as the resulting prepared file is still not
   processed into a working cache.php file for reasons unknown as yet… in any case
   I hope this input helps resolve the memory issue.

 * You wrote (to the authors):
 * > thanks for a great plugin by the way
 * And I second that thank you!
 * Thanks, to you, for making these suggestions. I hope that they might be useful
   to the plugin authors. Any methods that might allow the plugin to be updated 
   in a timely fashion would be great.
 * I can’t comment on whether or not your suggestions for auto-updating will work;
   your coding skills are a bit beyond mine, and I can’t evaluate your proposals.
 * The updating method _now _in use – roughly, “Let us know when it’s out of date
   and we’ll update it.” – isn’t working especially well (although that may be due
   to a summer vacation or similar.)
 * Luckily, the first place that the staleness shows up seems to be in the (mis)
   reporting of the Chrome browser version, which is probably not “mission critical”
   to many projects, so I’m just relying on patience instead.

 * well, the underlying phpbrowscap class used is not by the plugin authors, so 
   they can’t really be expected to update that, I didn’t realize it to begin with…
   I posted a separate topic for a memory improvement in the plugin itself, but 
   my suggestions above I might fork it on github instead.
 * [https://github.com/GaretJax/phpbrowscap/](https://github.com/GaretJax/phpbrowscap/)
 * you might also try replacing the Browscap.php class with that version and see
   if the auto-update processes (since it’s part of that class not the plugins so
   much.) but there are other things that may be different (eg. namespace and default
   settings.)
 * as for the Chrome issue, it could also be a fairly safe assumption since is_chrome()
   will still return true, that if the version is returning 0.0, and since 0.0 doesn’t
   exist, that it actually could be used in a *positive sense* to test *for* the
   latest version of Chrome. `is_chrome('0.0')`
    because as at this point (using
   the plugin) Chrome 43 will return 43 fine but Chrome 44 will return 0.0… just
   saying.
