[PHP] Hàm phpinfo trong PHP

1. Định nghĩa
- Hàm phpinfo() in ra chi tiết các thông số cấu hình PHP trên máy chủ của bạn. Hàm sẽ hiển thị tất cả các thông tin về PHP như phiên bản, các modules đang bật, đường dẫn php.ini, thông số của từng cấu hình chi tiết,...

2. Cú pháp

Mã nguồn PHP:

phpinfo(int $flags = INFO_ALL): true

- hàm phpinfo() xuất ra một lượng lớn thông tin về trạng thái hiện tại của PHP. Bao gồm thông tin về các tùy chọn và phần mở rộng biên dịch PHP, phiên bản PHP, thông tin máy chủ và môi trường (nếu biên dịch dưới dạng mô-đun), môi trường PHP, thông tin phiên bản hệ điều hành, đường dẫn, giá trị chính và cục bộ của các tùy chọn cấu hình, tiêu đề HTTP và Giấy phép PHP
- vì mỗi hệ thống được thiết lập khác nhau nên phpinfo() thường được sử dụng để kiểm tra các thiết lập cấu hình và các biến được xác định trước có sẵn trên một hệ thống nhất định.
- hàm phpinfo() cũng là một công cụ gỡ lỗi hữu ích vì nó chứa tất cả dữ liệu EGPCS (Môi trường, GET, POST, Cookie, Máy chủ).

3. Tham số
- mặc định không tham số, hàm phpinfo() sẽ xuất ra toàn bộ thông tin cấu hình PHP trên máy chủ đang sử dụng
- tham số tùy chọn $flags các bạn tham khảo bảng dưới đây:

Name (constant) Value Description

INFO_GENERAL 1 Dòng cấu hình, vị trí php.ini , ngày xây dựng, Máy chủ web, Hệ thống và nhiều thông tin khác

INFO_CREDITS 2 Tín dụng PHP. Xem thêm phpcredits()

INFO_CONFIGURATION 4 Giá trị Local và Master hiện tại cho các chỉ thị PHP. Xem thêm ini_get()

INFO_MODULES 8 Các mô-đun đã tải và các thiết lập tương ứng của chúng. Xem thêm get_loaded_extensions()

INFO_ENVIRONMENT 16 Thông tin về Biến môi trường cũng có sẵn trong $_ENV

INFO_VARIABLES 32 Hiển thị tất cả các biến được xác định trước từ EGPCS (Môi trường, GET, POST, Cookie, Máy chủ)

INFO_LICENSE 64 Thông tin về giấy phép PHP. Xem thêm » Câu hỏi thường gặp về giấy phép

INFO_ALL -1 Hiển thị tất cả các nội dung trên

4. Kết quả trả về
- hàm luôn luôn trả về: true.

5. Ví dụ:
- ví dụ 1:
+ input:

Mã nguồn PHP:

<?php // Show all information, defaults to INFO_ALL phpinfo(); // Show just the module information. // phpinfo(8) yields identical results. phpinfo(INFO_MODULES); ?>

+ output:
