How to implement automatic jump execution in php

After executing the show in A, it will automatically jump to execute B. How to implement it specifically (⊙o⊙)?

You can write javascript tags
echo " type='text/javascript'>";

echo "window.location.href='https://www.csdn.net'";

echo "< /script>";

Are A and B two pages or what? Is show a server function or a client js function? If it is a server, just execute show and then redirect to B.

thinkphp? Just add a parameter
