PHP does not detect Netscape for Windows ua: Mozilla/4.8 [en] (Windows NT 5.0; U) It did detect Mozilla 1.2 and IE 6 for Windows and Mozilla 1.1 and Netscape 4.7 in Linux.

The latest verion (downloaded January 5 2003) of browsecap.ini was used.

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PHP.

Contact the developer mantaining the browsecap.ini, this is not a PHP bug.

Ilia, I am the developer of the browscap.ini file that PHP recommends to its users. Respectfully, this issue does appear to be a bug in PHP. The user agent in question, Mozilla/4.8 [en] (Windows NT 5.0; U), is in my browscap.ini file and it is recognized when Serge visits my website which uses IIS. To me that suggests a bug in get_browser().

I am suspicious that in certain situations get_browser() has a problem dealing with multiple question marks in a user agent. In an attempt to prove my theory I changed the definition for the user agent in question and asked Serge to see if it works. I'll report back here on his results.

I updated the browscap.ini and the detection works fine now with Netscape for windows:

ua: Mozilla/4.8 [en] (Windows NT 5.0; U)
pattern match: browser_name_pattern Mozilla/4\.8.*(Windows NT 5\.0; U)

Thanks, Serge.

Ilia, I think this is fairly solid proof that my suspicions are correct about get_browser() having a problem dealing with multiple question marks in the user agent.

The old definition in my browscap.ini file: Mozilla/4.8 ???? (Windows NT 5.0; U) fails while the updated definition: Mozilla/4.8*(Windows NT 5.0; U) works fine.

Both definitions work fine with browscap.dll therefore I suspect a problem with get_browser().
