I set up a CRUD and posted the message "Record updated successfully." to appear as soon as the registration is completed, but no matter which page I go to, the message continues, I want as soon as I click the button close he clears the message

  <div class="alert alert-<?php echo $_SESSION['type']; ?> alert-dismissible" role="alert">
    <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>    
    <?php echo $_SESSION['message']; ?> 
  </div>  
<?php endif; ?>
php session

If your goal is to present only once the message (and it is not included in the question, but I imagine there is one if(isset($_SESSION['message'])), then just do unset($_SESSION['message']); after displaying the message.

Ex:

<?php if(isset($_SESSION['message'])): ?>
  <div class="alert alert-<?php echo $_SESSION['type']; ?> alert-dismissible" role="alert">
    <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>    
    <?php echo $_SESSION['message']; ?> 
  </div>
<?php endif; ?>

Another option would be to use query strings instead of $_SESSION. Thus the value disappears when another page is loaded (or the same without the query string).
