سلام دوستان
مشکلی برای یکی از اسکریپت هایی که دارم پیش اومده.
توابع استفاده شده در این اسکریپت، از نسخه 5 پشتیبانی می کنه منتها نسخه Php سرور هاستی که استفاده می کنم 7 به بالا هست.
متأسفانه من نمی تونم به دیتابیس وصل بشم.
من تمام sql ها را به sqli تغییر دادم ولی جواب نداد.
زمانی که نسخه Php روی 5 بود این اسکریپت به راحتی کار می کرد ولی الان، فقط یه صفحه ی سیاه ظاهر میشه بدون هیچ نوشته ای.
فایل کلاس اتصال به دیتابیس رو براتون ارسال می کنم.
ممنون میشم توابع این فایل رو برام درست کنید تا قابل استفاده در نسخه های 7 به بالا باشه.
لطفا توابع درون این فایل رو عوض نکنید و فقط توابعی که مربوط به sql هست رو تغییر بدید.
با احترام.
مثل این که نمیشه فایل php رو ارسال کنم. ناچارا کدها رو در این جا قرار میدم:
