Summary: get_browser fails on 7.0 with user agent of null

There seems to be a logic error in the detection of the user
agent[1]. zend_is_auto_global_str(ZEND_STRL("_SERVER"))) yields 1,
and so the error is triggered.
Is it supposed to be
!zend_is_auto_global_str(ZEND_STRL("_SERVER")))?
@laruence: Can you please have a look at the issue?

I can confirm this issue for PHP 7.0.0-alpha2 with the CLI server
on Windows. Works fine with PHP 5.6.10, though. I'll do some
debugging.

Perhaps I did not make it clear. The problem only exists when you use a value of NULL for the user
agent parameter. It works when I provide $_SERVER["HTTP_USER_AGENT"] for that parameter.
I don't think that the problem has anything to do with the fastcgi configuration because of two
reasons:
1) I am using Apache 2.4 and php-fpm not nginx
2) It works with the same configuration on the same machine under 5.6.8
The following is the output when I first echo $_SERVER["HTTP_USER_AGENT"] and then call
get_browser(NULL, true). I included 2 "<br>" after echoing
$_SERVER["HTTP_USER_AGENT"] to delineate that output from that of get_browser.
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:38.0) Gecko/20100101 Firefox/38.0
Warning: get_browser(): HTTP_USER_AGENT variable is not set, cannot determine user agent name in
/usr/local/apache2/htdocs/php7testing/browscap_test.php on line 3
The main reason that I am bringing this up is that PHP 7 behavior is different from 5.6 and from the
documentation. I am trying to help eliminate problems for others making the transition from 5.X to
7.

you can check $_SERVER["HTTP_USER_AGENT"] by dumping it before calling get_browse, this
probably relates to some issue of your configuration in nginx fastcgi params

Using the code snippet in this report:
With 5.6.8 I do not get a warning and I get the following output from print_r:
Array ( [browser_name_regex] => ~^mozilla/5\.0 \(.*windows nt 6\.1.*\) gecko.* firefox/38\.0.*$~
[browser_name_pattern] => Mozilla/5.0 (*Windows NT 6.1*) Gecko* Firefox/38.0* [parent] =>
Firefox 38.0 [platform] => Win7 [comment] => Firefox 38.0 [browser] => Firefox [version]
=> 38.0 [device_type] => Desktop [ismobiledevice] => [istablet] => )
With 7.0 Alpha 2 I get the warning listed in this bug report and I do not get any output from
print_r.
The tests are run on the same machine. To change versions I stop php-fpm, run make install for the
version that I want, and then start php-fpm.
