ايها الاخوة اليكم سكريبت جالب مواقع بسيط بلغة بي اتش بي
اشتغل معي بس مو بالشكل اللازم
الفكرة حلوة انك تحدد الصفحة اللي بدك ياها و لنقل صفحة الطقس في ياهوو و تحددله كود html اللي بدك يجبلك ياه محدث عن طريق تحديد بداية و نهاية الكود
و الباقي عليه
جربوه و بتمنى من الاخوة اللي عندهم سكريبتات فعالة بتعمل نفس العمل ما تبخل علينا فيها
