I would like to be doing a PHP contactor in which I might be setting a time for the next number to appear. For example, the number 1 appears and then the number 2 appears replacing the number 1. It would be in the sort of a stopwatch.
Can you tell me a function that does this number substitution and another one to determine the time the next number appears?
Thank you in advance.
Well, you need to do the counter in php, something like this:
<?php
$num = isset($_REQUEST["n"]) ? $_REQUEST["n"] : 0; //recebe o numero pela url
$num++; //inclementa o numero
?>
Next comes the JavaScript part (put this at the end of the php file):
<script>
setTimeout(function(){ //faz um teporizador
location.href = location.href + "?n=<?=$num?>"; //atualiza a página com o $num novo
}, 1000); //1000 milisegundos, ou seja 1s
</script>
