[PHP] DotArray - Accessing arrays using dot notation and asterisk.

//Get all users names with DotArray
$names = $dot->get('users.*.name');

Examples

Traditional way

$array['users']['raggi']['name'] = 'Moamen Eltouny';

echo $array['users']['raggi']['name']; // Moamen Eltouny

DotArray way (with DotArray Object)

$dot = dot(); // Creating DotArray Object
$dot->set('users.raggi.name', 'Moamen Eltouny');

// Getting [DotArray way]
echo $dot->get('users.raggi.name');

// OR Getting [ArrayAccess way]
echo $dot['users.raggi.name'];

Install

Install the latest version using Composer:

$ composer require pharaonic/php-dot-array

Usage

Create a new DotArray object:

$dot = new \Pharaonic\DotArray\DotArray;

// With existing array
$dot = new \Pharaonic\DotArray\DotArray($array);

OR You can use a helper function to create the object:

$dot = dot();

// With existing array
$dot = dot($array);

Methods

DotArray has the following methods:

• set()
• get()
• toJson()
• all()
• delete()
• clear()
• has()
• count()
• isEmpty()
• setArray()
• setReference()

<a name="set"></a>

set()

Sets a given key / value pair:

$dot->set('users.raggi.created_at', date('r', time()));

// ArrayAccess
$dot['users.raggi.created_at'] = date('r', time());

<a name="get"></a>

get()

Returns the value of a given key:

print_r($dot->get('users.*.name'));

// ArrayAccess
print_r($dot['users.*.name']);

Returns a given default value, if the given key doesn't exist:

print_r($dot->get('users.*.name', 'Raggi'));

<a name="tojson"></a>

toJson()

Returns the value of a given key (like get() method) as JSON:

echo $dot->toJson('users');

Returns all the stored items (like get() method) as JSON:

echo $dot->toJson();

<a name="all"></a>

all()

Returns all the stored items as an array:

$values = $dot->all();

<a name="delete"></a>

delete()

Deletes the given key:

$dot->delete('users.*.name');

// ArrayAccess
unset($dot['users.*.name']);

<a name="clear"></a>

clear()

Deletes all the stored items:

$dot->clear();

<a name="has"></a>

has()

Checks if a given key exists (returns boolean):

$dot->has('users.raggi.name');

// ArrayAccess
isset($dot['users.raggi.name']);

<a name="count"></a>

count()

Returns the number of the root Items:

$dot->count();

// Or use count() function [Countable Way]
count($dot);

Returns the number of items in a given key:

$dot->count('users');

<a name="isempty"></a>

isEmpty()

Checks if a given key is empty (returns boolean):

$dot->isEmpty('users.raggi.name');

// ArrayAccess
empty($dot['users.raggi.name']);

Checks the whole DotArray object:

$dot->isEmpty();

<a name="setarray"></a>

setArray()

Replaces all items in DotArray object with a given array:

$dot->setArray($array);

<a name="setreference"></a>

setReference()

Replaces all items in Dot object with a given array as a reference:

$dot->setReference($array);
