Guys you know that sometimes when browsing a website we use to be directed to another website like bet9ja so I want to ask what's the code to do it

Javascript will do that

Javascript. An example
<script>

//tell the browser where to redirect to
var goto = "https://bet9ja.com";

//redirect after 5 seconds
window.setTimeout(function(){
window.location.href = goto;
}, 5000);

</script>

Hope it helps

let's say for example you want to redirect to www.google.com using PHP, do like this;
inside your php script write

<?php
header('location:https://www.google.com');
?>
