Previous/Current iterator
=========================

[](#previouscurrent-iterator)

Allows iteration over an array but returns two items at a time stepping by one item at a time. Thus, the iterator for

```
['a', 'b', 'c', 'd']
```

Will return

```
['previous' => 'a', 'current' => 'b']
['previous' => 'b', 'current' => 'c']
['previous' => 'c', 'current' => 'd']
```

Current/Next iterator
=====================

[](#currentnext-iterator)

Allows iteration over an array but returns two items at a time stepping by one item at a time. Thus, the iterator for

```
['a', 'b', 'c', 'd']
```

Will return

```
['current' => 'a', 'next' => 'b']
['current' => 'b', 'next' => 'c']
['current' => 'c', 'next' => 'd']
['current' => 'd', 'next' => null]
```

Installation
============

[](#installation)

To install it, just include this requirement into your composer.json

```
{
    "require": {
        "crazycodr/previous-current-iterator": "1.*"
    }
}
```

And then run composer install/update as necessary.

Supports
========

[](#supports)

Only PHP 5.5 or more can be supported due to the fact that key() can only return arrays starting with PHP 5.5!

Examples
========

[](#examples)

To use the PreviousCurrentIterator, just instanciate a copy with an array and foreach it!

```
$data = ['a', 'b', 'c', 'd'];
foreach(new PreviousCurrentIterator($data) as $keys => $values) {
    //Compare previous and current
    if ($values['previous'] !== $values['current']) {
        echo 'Not the same';
    }
}
```

To use the CurrentNextIterator, just instanciate a copy with an array and foreach it!

```
$data = ['a', 'b', 'c', 'd'];
foreach(new CurrentNextIterator($data) as $keys => $values) {
    //Compare previous and current
    if ($values['next'] !== null) {
        if ($values['current'] !== $values['next']) {
            echo 'Not the same';
        }
    }
}
```

Use cases
=========

[](#use-cases)

Practical if you need to compare two items together in a previous vs current or current vs next manner.
