PHP Functions - Return values

chinmay.sahoo · Jul 24, 2017

Functions can also be used to return values.

<html>
<body>
<?php
function add($x,$y)
{
$total = $x + $y;
return $total;
}
echo "1 + 16 = " . add(1,16);
?>
</body>
</html>

The output of the code above will be:

1 + 16 = 17

The PHP $_GET and $_POST variables are used to retrieve information from forms, like user input.

If your function is a class method, and you don’t have anything useful to return, it might be worth just returning the instance so you can chain methods.
