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

Note

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