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 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77338&edit=1
