If I was programming this I would probably create 16 functions for
whatever the formula is supposed to produce. If you believe that a
constant will usually work you can have that as a default.
<?php
define('TABLE_STANDARD_ERROR', 1.6875);
function table_get_length($top, $plumb, $se = null) {
if (null === $se) {
$se = TABLE_STANDARD_ERROR;
}
return $top + $se + $plumb;
}
/** Now the fun begins... assume that $_POST is populated with data and
it has been scrubbed for improper input... */
$length = table_get_length($_POST['top'], $_POST['plumb'], $_POST['se']);
echo "In order to make the table, you need $length inches of wood.\n"
?>
