PHP là ngôn ngữ kịch bản phía máy chủ được thiết kế dành riêng cho phát triển web. Bạn có thể học PHP từ đầu bằng cách làm theo Hướng dẫn PHP và Ví dụ về PHP này
Trả về được sử dụng để làm gì trong PHP?
Mục đích của câu lệnh return trong PHP là để trả lại quyền kiểm soát thực thi chương trình về môi trường mà nó được gọi . Khi quay lại, việc thực thi biểu thức theo sau biểu thức đã gọi hàm hoặc mô-đun khác.
Tiếng vang có giống như trả về PHP không?
Echo dùng để hiển thị, trong khi return dùng để lưu trữ giá trị , giá trị này có thể được sử dụng hoặc không để hiển thị hoặc mục đích sử dụng khác.
Bạn có thể trả lại echo PHP không?
Cả hai đều dùng để xuất dữ liệu ra màn hình. Sự khác biệt là nhỏ. echo không có giá trị trả về trong khi print có giá trị trả về là 1 nên có thể sử dụng nó trong các biểu thức.
Bạn có thể trả về một chuỗi trong PHP không?
PHP. hàm strval[]
. Hàm này trả về một chuỗi . Chuỗi này được tạo bằng cách đánh máy giá trị của biến được truyền cho nó dưới dạng tham số. Các chương trình dưới đây minh họa hàm strval[]. tiếng vang strval [ $var_name ];
