DomToArray

This package provides an easy way to convert DOMDocument to PHP array.

DomToArray supports attributes, cdata and array like elements.

Main usage is to convert any XML API response to array. DomToArray consumes good old PHP DOMDocument object. XML API responses are strings which could be flawlessly loaded to DOMDocument with vaclavvanik/dom-loader.

Install

You can install this package via composer.

composer require vaclavvanik/dom-to-array

Usage

Simply pass DOMDocument

<?php

declare(strict_types=1);

use DOMDocument;
use VaclavVanik\DomToArray;

$doc = new DOMDocument();
$doc->loadXML('<root/>');

$result = DomToArray::toArray($doc);
// $result = ['root' => ''];

Array elements

Multiple elements with same name will create multidimensional array.

<root>
    <name>guy collection</name>
    <good_guy>
        <name>Luke Skywalker</name>
        <weapon>Lightsaber</weapon>
    </good_guy>
    <good_guy>
        <name>Gandalf</name>
        <weapon>Staff</weapon>
    </good_guy>
    <bad_guy>
        <name>Saruman</name>
        <weapon>Staff</weapon>
    </bad_guy>
    <bad_guy>
        <name>Sauron</name>
        <weapon>Ring</weapon>
    </bad_guy>
</root>

This will result in:

$result = [
    'root' => [
        'name' => 'guy collection',
        'good_guy' => [
            [
                'name' => 'Luke Skywalker',
                'weapon' => 'Lightsaber',
            ],
            [
                'name' => 'Gandalf',
                'weapon' => 'Staff',
            ],
        ],
        'bad_guy' => [
            [
                'name' => 'Saruman',
                'weapon' => 'Staff',
            ],
            [
                'name' => 'Sauron',
                'weapon' => 'Ring',
            ],
        ],
    ],
];

Attributes

Element attributes create key => value like element_name@attribute_name => attribute_value

<root attr="val">
    <single type="any"/>
    <collection type="any1"/>
    <collection type="any2"/>
    <author lang="English">Tolkien</author>
    <guy lang="Black Speech">
        <name weapon="Ring">Sauron</name>
        <weapon>Ring</weapon>
    </guy>
    <guy lang="Elvish">
        <name weapon="Staff">Gandalf</name>
        <weapon>Staff</weapon>
    </guy>
    <bad_guy lang="Unknown">
        <name weapon="Staff">Saruman</name>
        <name weapon="Ring">Sauron</name>
    </bad_guy>
</root>

This will result in:

$result = [
    'root' => [
        'single' => '',
        'single@type' => 'any',
        'collection' => [
            ['collection@type' => 'any1'],
            ['collection@type' => 'any2'],
        ],
        'author' => 'Tolkien',
        'author@lang' => 'English',
        'guy' => [
            [
                'name' => 'Sauron',
                'name@weapon' => 'Ring',
                'weapon' => 'Ring',
                'guy@lang' => 'Black Speech',
            ],
                'name' => 'Gandalf',
                'name@weapon' => 'Staff',
                'weapon' => 'Staff',
                'guy@lang' => 'Elvish',
            ],
        ],
        'bad_guy' => [
            [
                'name' => 'Saruman',
                 'name@weapon' => 'Staff',
            ],
            [
                'name' => 'Sauron',
                'name@weapon' => 'Ring',
            ],
        ],
        'bad_guy@lang' => 'Unknown',
    ],
    'root@attr' => 'val',
];

Cdata

Cdata are convert same as element text content.

<root>
    <good_guy>
        <name><![CDATA[<h1>Gandalf</h1>]]></name>
        <weapon>Staff</weapon>
    </good_guy>
</root>

This will result in:

$result = [
    'root' => [
        'good_guy' => [
            'name' => '<h1>Gandalf</h1>',
            'weapon' => 'Staff',
        ],
    ],
];

DomOptions

Sometimes it is useful to work only with elements (attributes are not needed).

<?php

declare(strict_types=1);

use DOMDocument;
use VaclavVanik\DomToArray;

$domOptions = DomOptions::fromArray([DomOptions::SKIP_ATTRIBUTES => true]);
$result = DomToArray::toArrayWithOptions($doc, $domOptions);

<root attr="val">
    <single type="any"/>
    <collection type="any1"/>
    <collection type="any2"/>
    <author lang="English">Tolkien</author>
    <guy lang="Black Speech">
        <name weapon="Ring">Sauron</name>
        <weapon>Ring</weapon>
    </guy>
    <guy lang="Elvish">
        <name weapon="Staff">Gandalf</name>
        <weapon>Staff</weapon>
    </guy>
    <bad_guy lang="Unknown">
        <name weapon="Staff">Saruman</name>
        <name weapon="Ring">Sauron</name>
    </bad_guy>
</root>

This will result in:

$result = [
    'root' => [
        'single' => '',
        'collection' => ['', ''],
        'author' => 'Tolkien',
        'guy' => [
            [
                'name' => 'Sauron',
                'weapon' => 'Ring',
            ],
            [
                'name' => 'Gandalf',
                'weapon' => 'Staff',
            ],
        ],
        'bad_guy' => [
            'name' => ['Saruman', 'Sauron'],
        ],
    ],
];
