JOIN FETCH có thể chậm hơn N+1 khi xử lý dữ liệu 1-n nhiều quan hệ trong Doctrine. Khi truy vấn nhiều quan hệ OneToMany, JOIN FETCH tạo ra bảng kết quả bùng nổ (ví dụ 3 ảnh × 5 đánh giá = 15 dòng/sản phẩm cho 2000 sản phẩm → ~30k dòng), dù Doctrine ẩn trùng lặp. Giải pháp mới từ bundle Symfony-Aggregated-Queries cho phép tối ưu bằng cách trả về mảng JSON thay vì entity, giảm 70% thời gian và 68% bộ nhớ so với JOIN FETCH. #Doctrine #HiệuSuất #Symfony #PHP #CơSởDữLiệu #API #BảnHiệuChỉnh

Tính năng "dynamic properties" trong PHP đã bị loại bỏ từ PHP 9.0, gây lỗi fatal nếu dùng. Nguyên nhân: dễ gây lỗi do gõ sai, thiếu kiểm soát kiểu dữ liệu, IDE không hỗ trợ. Cách khắc phục: khai báo rõ ràng thuộc tính, dùng constructor promotion, hoặc `$fillable`, `$casts` trong Laravel. Dùng `#[\AllowDynamicProperties]` chỉ cho mã cũ. ✅ PHP hiện đại: rõ ràng, an toàn, dễ bảo trì. #PHP #Laravel #WebDev #Programming #CleanCode #Backend #PHP9 #TypeSafety #Vietnamese #LậpTrình #MãNguồnSạch

@pwaring Probably controversial but I really dislike #PHP’s approach to arrays!

Just spent far too long trying to work out why JavaScript would consider one variable to be of type Array but not another.
Turns out if you have an array but it doesn't start at zero (and maybe is not continuous), JavaScript assumes it's not an Array and won't let you call forEach.
The fix is to reindex the array in PHP (the backend for this project):
$js_array = array_values($php_array);
