Replace placeholder "name" with "subject"
The `{{name}}` placeholder could represent different things depending on
the state of the Result, and referring to it as `{{name}}` seems
arbitrary. This commit changes it to `{{subject}}`, which is much more
generic and it describes well what that placeholder can mean.

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