I want to make a cookie in php which does this: Displays a message when I visit the site (for example <h1>Hello!</h1>), and then I can choose if I want to display that message the next time I visit the site.

 

Any tips for how I can make this cookie?

<?php

if( empty( $_COOKIE['visited'] ) )
{
setcookie('display', "Hello!");
setcookie('visited', true);
}


if( isset( $_COOKIE['visited'] ) && !empty( $_COOKIE['display'] ) )
{
echo "<h1> {$_COOKIE['display']} </h1>";

}

if( isset( $_POST['submit'] ) )
{
setcookie('display', false);
}
?>

<form action="" method="post">
<input type="submit" name="submit" value="Don't display" />
</form>

 

Something like this?
