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()->assert([]); // Validation passes successfully v::iterableVal()->assert(new ArrayObject()); // Validation passes successfully v::iterableVal()->assert(new stdClass()); // Validation passes successfully v::iterableVal()->assert('string'); // → "string" must be iterable Note This validator doesn't behave as PHP's is_iterable() function because it considers that you can iterate over any object.
