Method Listing

[](#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:

```

---

\#####`has()`

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

// true
```

---

\#####`first()`

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

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

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

---

\#####`flatten()`

```

---

\#####`last()`

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

```
$array = [100, 200, 300];

      return $value; // 300
});
```

---

\#####`only()`

Get a subset of the items from the given array:

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

];

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

// ['Desk', 'Chair']
```

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