Hi,
I'm curious if it's bad coding style for a function to return a value on
success, or simply "false" on fail. Here's what I mean:
<?php
function foo($number)
{
if (is_numeric($number)) {
return $number . ' is a number.';
} else {
return false;
}
}
if ($string = foo(1)) {
echo $string;
} else {
echo 'error';
}
?>
Is this ok?
Thank you,
Beau
