How do I return a value from a function?
The first time you create a function you might do something like this and get confused:
<?php
$value = 20;
function timestwo($value) { $result = $value * 2; }
$doubled = timestwo($value);
echo "$value doubled is $doubled";
//prints: 20 doubled is
?>
... and you get no value! That's because you need to use 'return' in the function, and it then works:
<?php
$value = 20;
function timestwo($value) { $result = $value * 2; return $result; }
$doubled = timestwo($value);
echo "$value doubled is $doubled";
//20 doubled is 40
?>
