أستفسار في كود أظهار المتصفح و أصدارة (أرجوا المساعده أثابكم الله)

السلام عليكم ورحمة الله وبركاته

أخواني أثابكم الله وأعانكم على طاعته

لدي كود يظهر نوع المتصفح وأصدارة وهو يعمل والحمد لله في كل المتصفحات لكن المشكلة فقط في متصفح

الأوبرا فلدي الأصدار 10.51 وعند تجربتي للصفحة يعطيني أن أصداره 9.80 وكذلك مع الأصدار الأحدث 10.53

يعطيني نفس النتيجة

ولكن أنظر الي الصفحة التالية فهي تعطي الأصدار الصحيح

http://www.useragentstring.com/index.php

فهل من الممكن التعديل عليه ليعطيني الأصدار الصحيح
