but php executed button clicked no

you can use confirm() method request confirmation user. returns boolean can use control logic flow. try this:

$('form').submit(function(e) {    if (!confirm('are sure want submit form?'))      e.preventdefault();  });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <form>    <button>submit</button>  </form>
