Use an asynchronous HTTP request in the JavaScript to load the output of the PHP script.

For example, using the Prototype framework's Ajax.Request, say you have an HTML element with id="notice" and you want to update that based on the script's output (a simple "true" or "false" string).

new Ajax.Request('/validate.php', {
  method: 'get',
  onSuccess: function(transport) {
    var notice = $('notice');
    if (transport.responseText == 'true')
      notice.update('Validation successful');
    else
      notice.update('Validation failed');
  }
});
