IterableVal

• IterableVal()

Validates whether the input is an iterable value, in other words, if you can iterate over it with the foreach language construct.

v::iterableVal()->isValid([]); // true
v::iterableVal()->isValid(new ArrayObject()); // true
v::iterableVal()->isValid(new stdClass()); // true
v::iterableVal()->isValid('string'); // false

Note

This validator doesn't behave as PHP's [is_iterable() function because it considers that you can iterate over any object.
