Hướng dẫn dùng gmt-5 time trong PHP

Để giải quyết vấn đề này có nhiều cách, tuy nhiên trong chuyên đề này mình đi về time trong php nên mình sẽ dùng luôn hàm set lại muối giờ:.

Nếu bạn muốn thay đổi cấu hình múi giờ cho PHP script, bạn có thể chèn đoạn mã sau vào phần mã PHP của bạn:

\\ echo “Original Time: “. date(“h:i:s”).”\n”;
putenv(“TZ=US/Eastern”);
\\ echo “New Time: “. date(“h:i:s”).”\n”;
?>

Danh sách các mã múi giờ để sử dụng thay cho giá trị “US/Eastern” trong hàm putenv() có thể tìm thấy ở đây.
