Im trying to do simple math in php and it works for the most part but cant work out how to do power of. For example i have
<?php
//variables and result
function bmi($height, $weight) {
$height = floatval($height);
$weight = floatval($weight);
return
$weight/($height*$height) )
}
?>but instead of $height*$height, i want to use something like $height^2
