1.2.907. PHP 7.1 Scalar Typehints¶
A new scalar typehint was introduced : iterable.
It can’t be used before PHP 7.1, and will be confused with classes or interfaces.
<?php
function foo(iterable $iterable) {
foreach ($iterable as $value) {
echo $value.PHP_EOL;
}
}
foo(range(1,20));
// works with array
foo(new ArrayIterator([1, 2, 3]));
// works with an iterator
foo((function () { yield 1; })() );
// works with a generator
?>
