Iter changelog

Changelog History

• v2.1.0 Changes

  September 19, 2020

  • ➕ Added iter\slice() method (#80). This works like explode() but produces an iterator.
  • ➕ Added iter\mapWithKeys() method (#81). This works like iter\map() but also passes keys as second parameter to the callable.

• v2.0.0 Changes

  May 30, 2019

  🚀 This release makes iter compatible with PHP 7.4 by renaming the iter\fn namespace to iter\func.

  • PHP >= 7.1 is now required. Functions are annotated with iterable types. (#52)
  • The iter\fn namespace has been renamed to iter\func. This is necessary for PHP 7.4 compatibility. (#79)
  • 0️⃣ Default $preserveKeys = false in chunk() and add chunkWithKeys() function.
  • Avoid advancing by one additional iteration in slice(). (#75)

• v1.6.0 Changes

  November 10, 2017

  • ➕ Added iter\enumerate() function (#43).
  • ➕ Added iter\isEmpty() function (#46).
  • ➕ Added $preserveKeys parameter to iter\chunk() (#42).

• v1.5.0 Changes

  April 26, 2017

  • ➕ Added $levels argument for flatten().
  • ➕ Added flatMap() function.

• v1.4.0 Changes

  September 27, 2016

  • 🛠 Fixed infinite loop when iter\zip() is called without arguments.
  • ➕ Added additional error checks for various "length" and "count" parameters (usually disallowing negative numbers).
  • The iter\flatten() function now preserves keys.
  • ➕ Added an iter\recurse() function. Example use is iter\recurse('iter\toArray', $data) which will recursively convert an iterator to array.

• v1.3.0 Changes

  October 21, 2015

  • ➕ Added Iterator iter\product(...$iterables):
    Returns the cartesian product iterator of the passed iterators. (#25)
  • ➕ Added bool iter\isIterable(mixed $value):
    Returns whether the value is an array or Traversable.
  • ➕ Added $key parameter to the callback of reduce() and reductions(). (#28)
  • ➕ Added support for <=> to fn\operator(). It is also supported on PHP versions that do not natively provide a <=> operator.
  • All functions now validate that inputs are iterables.

• v1.2.0 Changes

  March 08, 2015

  • ➕ Added new iter functions:
    • mixed search(callable $predicate, iterable $iterable):
      Returns the first value from $iterable which satisfies $predicate, or null if no such element exists.
    • Iterator reductions(callable $function, iterable $iterable, mixed $startValue = null):
      Returns an iterator which contains the intermediate values produced by applying a reduction function to an iterator. Can for example be used to compute cumulative sums.
  • 👍 Added support for the power operator (**) to iter\fn\operator(). Support is available also on older PHP versions which do not have an actual ** operator.

• v1.1.0 Changes

  March 27, 2014

  ➕ Added iter functions:

  • Iterator mapKeys(callable $function, iterable $iterable)
  • Iterator reindex(callable $function, iterable $iterable)
  • Iterator chunk(iterable $iterable, int $size)
  • Iterator flip(iterable $iterable)
  • string join(string $separator, iterable $iterable)

  ➕ Added iter\fn functions:

  • function nested_index(...$indices)

• v1.0.0 Changes
