This simple library provides functionality for [`array_column()`](http://php.net/array_column)to versions of PHP earlier than 5.5. It mimics the functionality of the built-in function in every way.

Usage
-----

[](#usage)

```
array array_column(array $input, mixed $columnKey[, mixed $indexKey])

```

Given a multi-dimensional array of data, `array_column()` returns the values from a single column of the input array, identified by the `$columnKey`. Optionally, you may provide an `$indexKey` to index the values in the returned array by the values from the `$indexKey` column in the input array.

For example, using the following array of data, we tell `array_column()` to return an array of just the last names, indexed by their record IDs.

```
