سلام
کدهای کلاس :
class bingo {
function read_test() {
echo 'Bingo';
}
}
فراخوانی :
<?php
$rd = new bingo;
echo $rd->read_test();
خطا :
نقل قول:Fatal error: Cannot declare class read, because the name is already in use in C:xampphtdocsahvazsellclassesclass.php on line 36
یک کلاس جدید ایجاد کردم و نام ها رو تغییر دادم اما فرقی نکرد.
تشکر.
کد کامل رو بگذارین. الان خطا داره میگه این اسم قبلاً استفاده شده. یه اسم جدید باید بدین که از قبل تعریف نشده باشه.
کدهای کامل فایل کلاس :
<?php
require_once 'config/config.php';
?>

بهتره همیشه کلاس‌هاتون رو توی فایلی جدا از ساختار HTML تعریف کنین و هروقت نیاز بهشون داشتین، با require_once فایل کلاس رو ضمیمه کنین و از اشیائی که از اون کلاس ایجاد میکنین استفاده کنین. ضمناً بهتره صراحتاً سطح دسترسی (public یا private یا protected) رو مشخص کنید.
