SplFloat::__construct
Here's a clearer example usage in case anyone else finds the
current documentation confusing (as I did).
<?php
class Fruit extends SplEnum
{
// If no value is given during object construction this value is used
const __default = 1;
// Our enum values
const APPLE = 1;
const ORANGE = 2;
}
$myApple = new Fruit();
$myOrange = new Fruit(Fruit::ORANGE);
$fail = 1;
function eat(Fruit $aFruit)
{
if (Fruit::APPLE == $aFruit) {
echo "Eating an apple.\n";
} elseif (Fruit::ORANGE == $aFruit) {
echo "Eating an orange.\n";
}
}
eat($myApple); // Eating an apple.
eat($myOrange); // Eating an orange.
eat($fail); // PHP Catchable fatal error: Argument 1 passed to eat() must be an instance of Fruit, integer given
?>
The SplEnum class
