PHP implements reminder to jump after a few seconds

php Scheduled jump We need to use the header function to enter html or js code to achieve scheduled jump. Let me introduce a simple example

php The code is as follows:

header("refresh:3;url=//m.sbmmt.com"); print('正在加载，请稍等...
三秒后自动跳转到PHP中文网~~~');

The output html code has the same effect as below.

This achieves automatic jump after 3 seconds.

What needs to be noted here is:If your file is uft-8 encoded, we must be careful not to have output or BOM characters in front of the header, which may cause the jump to fail.
