Create views of arrays, slice and index using Python-like notation, transform and select your data using chained and fluent operations. Features -------- [](#features) - Array views as an abstraction over an array - Forward and backward array indexing - Selecting and slicing using [Python-like slice notation](https://www.geeksforgeeks.org/python-list-slicing/) - Filtering, mapping, matching and masking - Chaining operations via pipes and fluent interfaces How to install to your project ------------------------------ [](#how-to-install-to-your-project) ``` composer require smoren/array-view ``` Usage ----- [](#usage) ### Indexing [](#indexing) Index into an array forward or backwards using positive or negative indexes. Data1234567*Positive Index*0*1**2**3**4**5**6**Negative Index**-7**-6**-5**-4**-3**-2**-1*``` use Smoren\ArrayView\Views\ArrayView; $view = ArrayView::toView([1, 2, 3, 4, 5, 6, 7]); $view[0]; // 1 $view[1]; // 2 $view[-1]; // 7 $view[-2]; // 6 ``` ### Slices [](#slices) Use [Python-like slice notation](https://www.geeksforgeeks.org/python-list-slicing/) to select a range of elements: `[start, stop, step]`. ``` use Smoren\ArrayView\Views\ArrayView; $originalArray = [1, 2, 3, 4, 5, 6, 7, 8, 9]; $view = ArrayView::toView($originalArray); $view['1:6']; // [2, 3, 4, 5, 6] $view['1:7:2']; // [2, 4, 6] $view[':3']; // [1, 2, 3] $view['::-1']; // [9, 8, 7, 6, 5, 4, 3, 2, 1] ``` Insert into parts of the array. ``` $view['1:7:2'] = [22, 44, 66]; print_r($originalArray); // [1, 22, 3, 44, 5, 66, 7, 8, 9] ``` ### Subviews [](#subviews) Create subviews of the original view using masks, indexes, and slices. ``` use Smoren\ArrayView\Selectors\IndexListSelector; use Smoren\ArrayView\Selectors\MaskSelector; use Smoren\ArrayView\Selectors\SliceSelector; use Smoren\ArrayView\Views\ArrayView; $originalArray = [1, 2, 3, 4, 5]; $view = ArrayView::toView($originalArray); // Object-oriented style $view->subview(new MaskSelector([true, false, true, false, true]))->toArray(); // [1, 3, 5] $view->subview(new IndexListSelector([1, 2, 4]))->toArray(); // [2, 3, 5] $view->subview(new SliceSelector('::-1'))->toArray(); // [5, 4, 3, 2, 1] // Scripting style $view->subview([true, false, true, false, true])->toArray(); // [1, 3, 5] $view->subview([1, 2, 4])->toArray(); // [2, 3, 5] $view->subview('::-1')->toArray(); // [5, 4, 3, 2, 1] $view->subview(new MaskSelector([true, false, true, false, true]))->apply(fn ($x) => x * 10); print_r($originalArray); // [10, 2, 30, 4, 50] ``` ### Subarray Multi-indexing [](#subarray-multi-indexing) Directly select multiple elements using an array-index multi-selection. ``` use Smoren\ArrayView\Selectors\IndexListSelector; use Smoren\ArrayView\Selectors\MaskSelector; use Smoren\ArrayView\Selectors\SliceSelector; use Smoren\ArrayView\Views\ArrayView; $originalArray = [1, 2, 3, 4, 5]; $view = ArrayView::toView($originalArray); // Object-oriented style $view[new MaskSelector([true, false, true, false, true])]; // [1, 3, 5] $view[new IndexListSelector([1, 2, 4])]; // [2, 3, 5] $view[new SliceSelector('::-1')]; // [5, 4, 3, 2, 1] // Scripting style $view[[true, false, true, false, true]]; // [1, 3, 5] $view[[1, 2, 4]]; // [2, 3, 5] $view['::-1']; // [5, 4, 3, 2, 1] $view[new MaskSelector([true, false, true, false, true])] = [10, 30, 50]; print_r($originalArray); // [10, 2, 30, 4, 50] ``` ### Combining Subviews [](#combining-subviews) Combine and chain subviews one after another in a fluent interface to perform multiple selection operations. ``` use Smoren\ArrayView\Selectors\IndexListSelector; use Smoren\ArrayView\Selectors\MaskSelector; use Smoren\ArrayView\Selectors\SliceSelector; use Smoren\ArrayView\Views\ArrayView; $originalArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; // Fluent object-oriented style $subview = ArrayView::toView($originalArray) ->subview(new SliceSelector('::2')) // [1, 3, 5, 7, 9] ->subview(new MaskSelector([true, false, true, true, true])) // [1, 5, 7, 9] ->subview(new IndexListSelector([0, 1, 2])) // [1, 5, 7] ->subview(new SliceSelector('1:')); // [5, 7] $subview[':'] = [55, 77]; print_r($originalArray); // [1, 2, 3, 4, 55, 6, 77, 8, 9, 10] // Fluent scripting style $originalArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; $subview = ArrayView::toView($originalArray) ->subview('::2') // [1, 3, 5, 7, 9] ->subview([true, false, true, true, true]) // [1, 5, 7, 9] ->subview([0, 1, 2]) // [1, 5, 7] ->subview('1:'); // [5, 7] $subview[':'] = [55, 77]; print_r($originalArray); // [1, 2, 3, 4, 55, 6, 77, 8, 9, 10] ``` ### Selectors Pipe [](#selectors-pipe) Create pipelines of selections that can be saved and applied again and again to new array views. ``` use Smoren\ArrayView\Selectors\IndexListSelector; use Smoren\ArrayView\Selectors\MaskSelector; use Smoren\ArrayView\Selectors\SliceSelector; use Smoren\ArrayView\Views\ArrayView; $originalArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; $selector = new PipeSelector([ new SliceSelector('::2'), new MaskSelector([true, false, true, true, true]), new IndexListSelector([0, 1, 2]), new SliceSelector('1:'), ]); $view = ArrayView::toView($originalArray); $subview = $view->subview($selector); print_r($subview[':']); // [5, 7] $subview[':'] = [55, 77]; print_r($originalArray); // [1, 2, 3, 4, 55, 6, 77, 8, 9, 10] ``` Documentation ------------- [](#documentation) For detailed documentation and usage examples, please refer to the [API documentation](https://smoren.github.io/array-view-php/packages/Application.html).
