Well, you need to store the last time someone sent a POST somewhere. You have several options:

In a cookie - This is not as safe as the other options, as the client can manipulate / remove the cookie.

In server session ($_SESSION) - This is the easiest way, since you don't need to track a specific client by IP or something like that.

In a database - This is the most flexible way, you can easily see and manage your clients.

Each time when someone makes a POST, check in your storage when they last did a post, and deny it if it was to soon.

You could also do this on client side, using javascript. However, that's not as safe as the client can disable/manipulate it.

One technique is to disable the submit button using javascript like so:

<form id="myform" name="myform" onsubmit="disableForATime();">
     <!-- form elements -->
     <input type="submit" value="Submit" id="submitButton" name="submitButton"/>
</form>

<script type="text/javascript">
      function disableForATime(){
             document.getElementById('submitButton').setAttribute('enabled', false);
             setTimeout(enableSubmit, 5000); //modify 5000 to be the number of milliseconds you would like to disable the button for.        
      }

      function enableSubmit(){
             document.getElementById('submitButton').setAttribute('enabled', true);
      }

</script>
