Method Listing

#####add()

Add a given key / value pair to the array if the given key doesn't already exist in the array:

$array = ArrayHelper::add(['card' => 'Visa'], 'price', 200);
// ['card' => 'Visa', 'price' => 200]

#####average()

Get the average value of a given key:

ArrayHelper::average([1, 2, 3, 4, 5]);
// 3

You may also pass a key to the average method:

$array = [
   ['score' => 10],
   ['score' => 30],
   ['score' => 50],
];

ArrayHelper::average($array, 'score');

// 30

#####collapse()

Collapse an array of arrays into a single array:

$array = ArrayHelper::collapse([[1, 2, 3], [4, 5, 6]]);

// [1, 2, 3, 4, 5, 6]

#####except()

Get all of the given array except for a specified array of items:

$array = ['name' => 'Desk', 'price' => 100];

$array = ArrayHelper::except($array, ['price']);

// ['name' => 'Desk']

#####has()

Check if an item exists in an array using "dot" notation:

$array = ['products' => ['desk' => ['price' => 100]]];

$hasDesk = ArrayHelper::has($array, 'products.desk');

// true

#####first()

Return the first element in an array passing a given truth test:

$array = [100, 200, 300];
$value = ArrayHelper::first($array); // 100

// or apply custom callback

$value = ArrayHelper::first($array, function($key, $value) {
      return $value >= 150; // 200
});

#####flatten()

Flatten a multi-dimensional array into a single level:

$array = ['name' => 'Bob', 'languages' => ['PHP', 'Python']];

$array = ArrayHelper::flatten($array);

// ['Bob', 'PHP', 'Python'];

#####last()

Return the last element in an array passing a given truth test:

$array = [100, 200, 300];
$value = ArrayHelper::last($array); // 300

// or apply custom callback

$value = ArrayHelper::last($array, function($key, $value) {
      return $value; // 300
});

#####only()

Get a subset of the items from the given array:

$array = ['name' => 'Desk', 'price' => 100, 'orders' => 10];

$array = ArrayHelper::only($array, ['name', 'price']);

// ['name' => 'Desk', 'price' => 100]

#####prepend()

Push an item onto the beginning of an array:

$array = ['one', 'two', 'three', 'four'];

$array = ArrayHelper::prepend($array, 'zero');

// $array: ['zero', 'one', 'two', 'three', 'four']

#####pluck()

The function retrieves all of the collection values for a given key:

$array = [
   ['product_id' => 'prod-100', 'name' => 'Desk'],
   ['product_id' => 'prod-200', 'name' => 'Chair'],
];


$plucked = ArrayHelper::pluck($array, 'name');

// ['Desk', 'Chair']

You may also specify how you wish the resulting collection to be keyed:

$plucked = ArrayHelper::pluck($array, 'name', 'product_id');

// ['prod-100' => 'Desk', 'prod-200' => 'Chair']

#####pull()

Get a value from the array, and remove it:

$array = ['name' => 'Desk', 'price' => 100];

$name = ArrayHelper::pull($array, 'name');

// $name: Desk

// $array: ['price' => 100]

#####set()

Set an array item to a given value using "dot" notation:

$array = ['products' => ['desk' => ['price' => 100]]];

ArrayHelper::set($array, 'products.desk.price', 200);

// ['products' => ['desk' => ['price' => 200]]]

#####sort()

Sort the array using the given callback:

$array = [
    ['name' => 'Desk'],
    ['name' => 'Chair'],
];

$array = ArrayHelper::sort($array, function ($value) {
    return $value['name'];
});

/*
    [
        ['name' => 'Chair'],
        ['name' => 'Desk'],
    ]
*/

#####sortRecursive()

Recursively sort an array by keys and values:

$array = [
      [
          'Desc',
          'Chair',
      ],
      [
          'PHP',
          'Ruby',
          'JavaScript',
      ],
];

$array = ArrayHelper::sortRecursive($array);
        
/*
  [
      [
         'Chair',
         'Desc',
      ],
      [
         'JavaScript',
         'PHP',
         'Ruby',
      ]
  ];
*/

#####where()

Filter the array using the given Closure.:

$array = ["100", 200, "300"];
$value = ArrayHelper::where($array, function($key, $value) {
   return is_string($value);
});
// Will be return Array ( [0] => 100 [2] => 300 );

#####xmlStrToArray()

Convert xml string to array.

$xml = '<?xml version="1.0"?>
          <root>
            <id>1</id>
            <name>Bob</name>
          </root>';
          
ArrayHelper::xmlStrToArray($xml)

// ['id' => 1, 'name' => 'Bob']

####StringHelper

  • StringHelper::removeStopWords('some text'); - remove stop words from string
  • StringHelper::removePunctuationSymbols('some text'); - Remove punctuation symbols from string
