IterableVal
February 3, 2026 · View on GitHub
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.
