Description:
------------
I noticed this bug while doing a batch of assertions on PHP 7.3.

get_browser('') will crash PHP.

In PHP 7.2 it would return an array.

Test script:
---------------
<?php
var_dump(get_browser(''));
?>

Expected result:
----------------
object(stdClass)#1 (10) { ["browser_name_regex"]=> string(6) "~^.*$~"
["browser_name_pattern"]=> string(1) "*" ["parent"]=> string(17)
"DefaultProperties" ["comment"]=> string(15) "Default Browser"
["browser"]=> string(15) "Default Browser" ["ismobiledevice"]=>
string(0) "" ["istablet"]=> string(0) "" ["version"]=>
string(3) "0.0" ["platform"]=> string(7) "unknown"
["device_type"]=> string(7) "unknown" }

Actual result:
--------------
Crash
