Question : PHP time diffrence and if statement

Dear Experts,
I need to check the time diffrence, I do not want my user to submit the form over and over again.
I already use Captcha by the way and I'm new to PHP.

$query = "SELECT Email,Date FROM mytable where Email='$visitoremail'";

$result = mysql_fetch_row($query);

$date_comingfrom_database = $result['Date'];

$todaysdate = date('Y-m-d H:i:s');

// I insert the date like this $todayis = date('Y-m-d H:i:s') ;

// I want to check the time diffrence and the email address, if the same email address has submited the form within 300 seconds (5 minutes) then
// echo "your message has already been submitted."
