Informations about the package array_column
array_column() for PHP
This simple library provides functionality for array_column()
to versions of PHP earlier than 5.5. It mimics the functionality of the built-in
function in every way.
Usage
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.
If we call print_r()
on $lastNames
, you'll see a resulting array that looks
a bit like this:
Installation
The easiest way to install this library is to use Composer:
Then, when you run composer install
, everything will fall magically into place,
and the array_column()
function will be available to your project, as long as
you are including Composer's autoloader.
However, you do not need Composer to use this library.
This library has no dependencies and should work on older versions of PHP.
Download the code and include src/array_column.php
in your project, and all
should work fine.
When you are ready to run your project on PHP 5.5, everything should continue to run well without conflicts, even if this library remains included in your project.
