Convert an array to xml

This package provides a very simple class to convert an array to an xml string.

Install

You can install this package via composer.

composer require spatie/array-to-xml

Usage

use Spatie\ArrayToXml\ArrayToXml;
...
$array = [
    'Good guy' => [
        'name' => 'Luke Skywalker',
        'weapon' => 'Lightsaber'
    ],
    'Bad guy' => [
        'name' => 'Sauron',
        'weapon' => 'Evil Eye'
    ]
];

$result = ArrayToXml::convert($array);

After running this piece of code $result will contain:

<?xml version="1.0"?>
<root>
    <Good_guy>
        <name>Luke Skywalker</name>
        <weapon>Lightsaber</weapon>
    </Good_guy>
    <Bad_guy>
        <name>Sauron</name>
        <weapon>Evil Eye</weapon>
    </Bad_guy>
</root>

Optionally you can set the name of the rootElement by passing it as the second argument. If you don't specify this argument (or set it to an empty string) "root" will be used.

$result = ArrayToXml::convert($array, 'customrootname');

By default all spaces in the key names of your array will be converted to underscores. If you want to opt out of this behaviour you can set the third argument to false. We'll leave all keynames alone.

$result = ArrayToXml::convert($array, 'customrootname', false);

You can use a key named _attributes to add attributes to a node.

$array = [
    'Good guy' => [
        '_attributes' => ['attr1' => 'value'],
        'name' => 'Luke Skywalker',
        'weapon' => 'Lightsaber'
    ],
    'Bad guy' => [
        'name' => 'Sauron',
        'weapon' => 'Evil Eye'
    ]
];

$result = ArrayToXml::convert($array);

This code will result in:

<?xml version="1.0"?>
<root>
    <Good_guy attr1="value">
        <name>Luke Skywalker</name>
        <weapon>Lightsaber</weapon>
    </Good_guy>
    <Bad_guy>
        <name>Sauron</name>
        <weapon>Evil Eye</weapon>
    </Bad_guy>
</root>

It is also possible to wrap the value of a node into a CDATA section. This allows you to use reserved characters.

$array = [
    'Good guy' => [
        'name' => [
            '_cdata' => '<h1>Luke Skywalker</h1>'
        ],
        'weapon' => 'Lightsaber'
    ],
    'Bad guy' => [
        'name' => '<h1>Sauron</h1>',
        'weapon' => 'Evil Eye'
    ]
];

$result = ArrayToXml::convert($array);

This code will result in:

<?xml version="1.0"?>
<root>
    <Good_guy>
        <name><![CDATA[<h1>Luke Skywalker</h1>]]></name>
        <weapon>Lightsaber</weapon>
    </Good_guy>
    <Bad_guy>
        <name>&lt;h1&gt;Sauron&lt;/h1&gt;</name>
        <weapon>Evil Eye</weapon>
    </Bad_guy>
</root>

If your input contains something that cannot be parsed a DOMException will be thrown.

To add attributes to the root element provide an array with an _attributes key as the second argument. The root element name can then be set using the rootElementName key.

$result = ArrayToXml::convert($array, [
    'rootElementName' => 'helloyouluckypeople',
    '_attributes' => [
        'xmlns' => 'https://github.com/spatie/array-to-xml',
    ],
], true, 'UTF-8');

Use a multi-dimensional array to create a collection of elements.

$array = [
    'Good guys' => [
        'Guy' => [
            ['name' => 'Luke Skywalker', 'weapon' => 'Lightsaber'],
            ['name' => 'Captain America', 'weapon' => 'Shield'],
        ],
    ],
    'Bad guys' => [
        'Guy' => [
            ['name' => 'Sauron', 'weapon' => 'Evil Eye'],
            ['name' => 'Darth Vader', 'weapon' => 'Lightsaber'],
        ],
    ],
];

This will result in:

<?xml version="1.0" encoding="UTF-8"?>
<helloyouluckypeople xmlns="https://github.com/spatie/array-to-xml">
    <Good_guys>
        <Guy>
            <name>Luke Skywalker</name>
            <weapon>Lightsaber</weapon>
        </Guy>
        <Guy>
            <name>Captain America</name>
            <weapon>Shield</weapon>
        </Guy>
    </Good_guys>
    <Bad_guys>
        <Guy>
            <name>Sauron</name>
            <weapon>Evil Eye</weapon>
        </Guy>
        <Guy>
            <name>Darth Vader</name>
            <weapon>Lightsaber</weapon>
        </Guy>
    </Bad_guys>
</helloyouluckypeople>
