Nãn thật ! bồ cài localhost vào rồi bồ đưa nó vào / giả sử là a.php
Bồ truy cập vào truyền các tham số cho nó:

Code:
http://localhost/a.php?logo=1


Hoặc dùng fopen để tạo 1 file.

Vâng, em xin tiếp thu.

Anh thông cảm chứ em là thợ lái máy ủi đá nên em không được học hành đến nơi đến chốn như anh. Em mày mò chỉ vì đam mê ngành IT mà thôi.

Nếu em được đi học Đại Học, Cao Đẳng như mọi người thì biết đâu em giỏi hơn và cái diễn đàn này lập ra là để ngắm chứ không có ai hỏi.

Nguỵ biện ! bồ không thích IT, không muốn tìm hiểu nó, không muốn học hỏi nó, thì học PHP làm gì cho nó phí giờ ?. Sao không dành công sức master cái máy ủi đá chẳng hơn là đi học thứ mình không rành à ?.

Đừng có nẩy người lên khi người ta xát muối vào, hơi đau đấy nhưng mà vết thương sẽ sớm khép miệng hơn.
