The above is the processing file written to the database by PHP.
For example, if the pc value is submitted as "ff" and the PHP file is successfully written to the database after submission, how can I automatically jump to the "ff" value link?

elseif($pc=="ff"){
$url="www.baidu.com";
Header("Location:$url"); 
exit;
}

This is how to automatically jump to this link after the database is successfully written.
------ Solution ----------------------
29 rows: $ pc = intval (R ('PC', 'P '));
All intval, whether it is hh ff or dd, and the last $ pc is 0, so it cannot jump.
In addition, the jump must start with "http: //".
