What is settimeout proper syntax?

Question

Hi I'm trying to use settimeout but gets an erro "Call to undefined function setTimeout() in". I based my code on w3schools. Here's my code:

<?php

function compareperc(){
    echo "hello";
}

setTimeout(compareperc(), 1000);

?>

To delay execution in PHP, you can use the following code:

<?php

function compareperc(){
    echo "hello";
}

sleep(1);
compareperc();

?>

I wouldn't necessarily say it's advisable, but this would be the equivalent without trying to use JavaScript where it won't work.
