PHP có các chức năng đơn giản để xử lý tất cả các tệp di chuyển, sao chép và xóa và hoàn toàn đúng - chúng đều là những việc rất phổ biến nên không có lý do gì làm khó chúng. Nếu bạn đang sử dụng Unix, bạn sẽ biết rằng không có lệnh "đổi tên", vì đổi tên tệp về cơ bản giống như di chuyển tệp, vì vậy bạn sử dụng lệnh di chuyển [mv] - lệnh này cũng giống như trong PHP
Các tệp được di chuyển bằng rename[], được sao chép bằng copy[] và bị xóa bằng unlink[]. Ban đầu, Unlink[] có vẻ như là một lựa chọn từ kỳ lạ, nhưng các hệ thống Unix coi tên tệp là "liên kết cứng" với chính các tệp thực tế, vì vậy để hủy liên kết một tệp là xóa nó
Ghi chú của tác giả. cả ba chức năng sẽ hoạt động mà không cần thêm thông tin từ bạn. Nếu bạn chọn chuyển một tệp hiện có sang tham số thứ hai của rename[], nó sẽ đổi tên tệp trong tham số một thành tệp trong tham số hai, ghi đè lên tệp gốc. Điều tương tự cũng áp dụng cho copy[] - bạn sẽ ghi đè lên tất cả các tệp mà không cần thắc mắc miễn là bạn có quyền chính xác

Hàm rename[] trong PHP là một hàm có sẵn dùng để đổi tên một tập tin hoặc thư mục. Nó cố gắng thay đổi tên cũ của tệp hoặc thư mục bằng tên mới do người dùng chỉ định và nó có thể di chuyển giữa các thư mục nếu cần.
Nếu tên mới do người dùng chỉ định đã tồn tại, hàm rename[] sẽ ghi đè lên tên đó. Tên cũ của tệp và tên mới do người dùng chỉ định được gửi dưới dạng tham số cho hàm rename[] và nó trả về True nếu thành công và Sai nếu không thành công.
cú pháp
rename[oldname, newname, context]
Thông số được sử dụng.
Hàm rename[] trong PHP chấp nhận ba tham số.
- tên Cu. Nó là một tham số bắt buộc chỉ định tên cũ của tệp hoặc thư mục
- tên mới. Đây là một tham số bắt buộc chỉ định tên mới của tệp hoặc thư mục
- định nghĩa bài văn. Đây là một tham số tùy chọn chỉ định hành vi của luồng
Giá trị trả về.
Trả về True khi thành công và Sai khi thất bại.
lỗi và ngoại lệ
- Hàm rename[] tạo Cảnh báo nếu tên mới đã tồn tại trong khi đổi tên thư mục
- Trình bao bọc được sử dụng trong tên cũ phải khớp với trình bao bọc được sử dụng trong tên mới
- Nếu hệ thống tệp đích không cho phép thực hiện lệnh gọi hệ thống chown[] và chmod[] trên tệp, thì hàm rename[] có thể tạo Cảnh báo
ví dụ
Input : $old_name = "gfg.txt" ;
$new_name = "newgfg.txt" ;
rename[ $new_name, $old_name] ;
Output : 1
Input : $old_name = "gfg.txt" ;
$new_name = "newgfg.txt" ;
if[file_exists[$new_name]]
{
echo "Error While Renaming $old_name" ;
}
else
{
if[rename[ $old_name, $new_name]]
{
echo "Successfully Renamed $old_name to $new_name" ;
}
else
{
echo "A File With The Same Name Already Exists" ;
}
}
Output : Successfully Renamed gfg.txt to newgfg.txt
