NO PR WILL BE ACCPETED HERE

A class to manipulate arrays in efficient ways to solve real world problems.

Requirement

1. PHP 7.2 or grater.
2. Composer.

Installation

Installing this package is very simple, first ensure you have the right PHP version and composer installed then in your terminal/(command prompt) run: composer require lablnet/arrays

Features

1. Determine whether the given dataSet is really array?

   • Example:

   •   use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $arr = array(2, 2, 3, 4, 4, 4, 4, 8, 8, 6, 6, 9, 9, 9, 9); 
       var_dump(Arrays::isReallyArray($arr)); //True
       var_dump(Arrays::isReallyArray([]));   //False

2. Determine the given array is (sequential)indexes.?

   • Example:

   •   use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $arr = array(2, 2, 3, 4, 4, 4, 4, 8, 8, 6, 6, 9, 9, 9, 9); 
       var_dump(Arrays::isSequential($arr)); //True
       var_dump(Arrays::isSequential(['a' => 1]));   //False

3. Determine the given array is assoc.?

   • Example:

   •   use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $arr = array(2, 2, 3, 4, 4, 4, 4, 8, 8, 6, 6, 9, 9, 9, 9); 
       var_dump(Arrays::isAssoc($arr)); //False
       var_dump(Arrays::isAssoc(['a' => 1]));   //True

4. Determine the given array is multi-dimensional.?

   • Example:

   •   use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $arr = array(2, 2, 3, 4, 4, 4, 4, 8, 8, 6, 6, 9, 9, 9, 9); 
       var_dump(Arrays::isMulti($arr)); //False
       var_dump(Arrays::isMulti(['a' => ['b' => 'c']]));   //True

5. Get the type of array.

   • Example:

   •   use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $arr = array(2, 2, 3, 4, 4, 4, 4, 8, 8, 6, 6, 9, 9, 9, 9); 
       var_dump(Arrays::getType($arr)); //indexes
       var_dump(Arrays::getType(['a' => ['b' => 'c']]));   //multi

6. Add an element to an array using "operation" notation if it doesn't exist.

   • Example:

   •   use Lablnet\Arrays;
       require '../vendor/autoload.php';
       var_dump(Arrays::add(['name' => 'desk', 'price' => null], 'price', 100)); // ['name' => 'desk', 'price' => 100]

7. Set an array item to a given value using "operator" notation.

   • Example:

   • use Lablnet\Arrays;
     require '../vendor/autoload.php';
     $array = ['products' => ['desk' => ['price' => 100]]];
     Arrays::set($array, 'products.desk.price', 200, '.');
     // ['products' => ['desk' => ['price' => 200]]]

8. Get an item from an array using "operator" notation(The Arrays::get method retrieves a value from a deeply nested array using "dot" notation:).

   • Example:

   •   use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $array = ['products' => ['desk' => ['price' => 100]]];
       $price = Arrays::get($array, 'products.desk.price', '.');
       // 100

The Arrays::get method also accepts a default value, which will be returned if the specific key is not found.

1. Determine if an item or items exist in an array using 'Operator' notation.

   • Example:

   •   use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $array = ['product' => ['name' => 'Desk', 'price' => 100]];
       $contains = Arrays::has($array, 'product.name', '.');
       // true
       $contains = Arrays::has($array, ['product.price', 'product.discount'], '.');
       // false

2. Determine if an item or items exist in an array using 'Operator' notation.

   • Example:

   •   use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $array = ['product' => ['name' => 'Desk', 'price' => 100]];
       $assoc = Arrays::multiToAssoc($array);
       // ['name' => 'Desk', 'price' => 100]

3. Converted a multi-dimensional associative array with dot.

   • Example:

   •   use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $array = ['products' => ['desk' => ['price' => 100]]];
       $dot= Arrays::dot($array);
       // ['products.desk.price' => 100]

4. Converted a multi-dimensional associative array with operator.

   • Example:

   •   use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $array = ['products' => ['desk' => ['price' => 100]]];
       $dot = Arrays::multiToAssocWithSpecificOpr($array);
       // ['products.desk.price' => 100]

5. Push an item onto the beginning of an array.

   • Example:

   •   use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $array = ['red', 'green', 'blue'];
       $prepend = Arrays::prepend($array, 'yellow');
       // ['yellow', 'red', 'green', 'blue'];

6. Push an item to the end of array.

   • Example:

   •   use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $array = ['red', 'green', 'blue'];
       $append = Arrays::append($array, 'yellow');
       // ['red', 'green', 'blue', 'yellow'];

7. Get the unique elements from arrays.

   • Example:

   •   use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $array = ['red', 'green', 'blue', 'red'];
       $unique = Arrays::append($array);
       // ['red', green', 'blue'];

8. Get a subset of the items from the given array.

   • Example:

   •   use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $array =  [
           'users' => 
           [
               'id' => 1,
               'name' => "Alex",
               'username' => 'peter',
           ],
           [
               'id' => 2,
               'name' => "Peter Khot",
               'username' => 'peter',
           ],
           [
               'id' => 3,
               'name' => "John",
               'username' => 'test',
           ]
       ];
       $subSetOfArray = Arrays::subSetOfArray($array, 'name');
       // [];

9. Remove one or many array items from a given array using "operator" notation.

   • Example:

   •   use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $array = ['products' => ['desk' => ['price' => 100]]];
       Arrays::forget($array, 'products.desk');
       // ['products' => []]

10. Get all of the given array except for a specified array of keys.

    • Example:

    •  use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $array = ['name' => 'Desk', 'price' => 100]
       $filtered = Arrays::except($array, ['price']);
       // ['name' => 'Desk']

11. Get a value from the array, and remove it.

    • Example:

    •  use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $array = ['name' => 'Desk', 'price' => 100];
       $name = Arrays::pull($array, 'name');
       // $array: ['price' => 100]

12. Changes the case of all keys in an array.

    • Example:

    •  use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $array = ['name' => 'Desk', 'price' => 100];
       $name = Arrays::arrayChangeCaseKey($array, CASE_UPPER);
       // ['NAME' => 'Desk', 'PRICE' => 100]

13. Changes the case of all values in an array.

    • Example:

    •  use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $array = ['name' => 'Alex'];
       $name = Arrays::arrayChangeCaseValue($array, CASE_UPPER);
       // ['name' => 'ALEX']

14. Remove duplicate values from array.

       $array = ````
       $name = Arrays::removeDuplicates($array);
       // $array: ['red', 'green', 'blue']

15. Get the most occurring value from array.

    • Example:

       ];
       $name = Arrays::query($array);
       // foo=bar&baz=boom&cow=milk&php=hypertext+processor

18. Filter the array using the given callback (THIS METION WILL NOT WORKS WITH MULTIDIMESSIONAL ARRAY.).

    • Example:

    •  use Lablnet\Arrays;
       require '../vendor/autoload.php';
       $array = [100, '200', 300, '400', 500];
       $array = Arrays::where($array, function ($value, $key) {
           return is_string($value);
       });
       // [1 => '200', 3 => '400']

19. Get one or a specified number of random values from an array.

    • Example:

       $array = [
           ['developer' => ['id' => 1, 'name' => 'Alex']],
           ['developer' => ['id' => 2, 'name' => 'Peter']],
       ];
       $name = Arrays::pluck($array, 'name');
       // ['Alex', 'Peter'];
