I tried ro do math with function in php

Question

<?php
$a = 1
$b = 1
function sayHello() {
echo $a / $b;
}

sayHello(); //call the function

?>

Help, please

Answer 1

the first answer is right, your function don't have access to the "$a" and "$b" variables, you should pass them as parameters

function sayHello($a,$b){
echo $a/$b;
}
sayHello(1,1);

Answer 2

your indentation for the calling of the function? That seems wrong...
