This package provides a very simple class to convert an array to an xml string.
We invest a lot of resources into creating best in class open source packages. You can support us by buying one of our paid products.
We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on our contact page. We publish all received postcards on our virtual postcard wall.
You can install this package via composer.
composer require spatie/array-to-xmluse 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, and _value to specify the value.
$array = [
'Good guy' => [
'_attributes' => ['attr1' => 'value'],
'name' => 'Luke Skywalker',
'weapon' => 'Lightsaber'
],
'Bad guy' => [
'name' => 'Sauron',
'weapon' => 'Evil Eye'
],
'The survivor' => [
'_attributes' => ['house'=>'Hogwarts'],
'_value' => 'Harry Potter'
]
];
$result = ArrayToXml::convert($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>
<The_survivor house="Hogwarts">
Harry Potter
</The_survivor>
</root>Note, that the value of the _value field must be a string. (More)
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><h1>Sauron</h1></name>
<weapon>Evil Eye</weapon>
</Bad_guy>
</root>If your input contains something that cannot be parsed a DOMException will be thrown.
You could specify specific values in for:
- encoding as the fourth argument (string)
- version as the fifth argument (string)
- standalone as sixth argument (boolean)
$result = ArrayToXml::convert($array, [], true, 'UTF-8', '1.1', [], true);This will result in:
<?xml version="1.1" encoding="UTF-8" standalone="yes"?>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>The package can also can handle numeric keys:
$array = [
100 => [
'name' => 'Vladimir',
'nickname' => 'greeflas',
],
200 => [
'name' => 'Marina',
'nickname' => 'estacet',
],
];
$result = ArrayToXml::convert(['__numeric' => $array]);This will result in:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<numeric_100>
<name>Vladimir</name>
<nickname>greeflas</nickname>
</numeric_100>
<numeric_200>
<name>Marina</name>
<nickname>estacet</nickname>
</numeric_200>
</root>You can change key prefix with setter method called setNumericTagNamePrefix().
The package can also can handle custom keys:
$array = [
'__custom:custom-key:1' => [
'name' => 'Vladimir',
'nickname' => 'greeflas',
],
'__custom:custom-key:2' => [
'name' => 'Marina',
'nickname' => 'estacet',
'tags' => [
'__custom:tag:1' => 'first-tag',
'__custom:tag:2' => 'second-tag',
]
],
];
$result = ArrayToXml::convert($array);This will result in:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<custom-key>
<name>Vladimir</name>
<nickname>greeflas</nickname>
</custom-key>
<custom-key>
<name>Marina</name>
<nickname>estacet</nickname>
<tags>
<tag>first-tag</tag>
<tag>second-tag</tag>
</tags>
</custom-key>
</root>A custom key contains three, colon-separated parts: "__custom:[custom-tag]:[unique-string]".
- "__custom"
- The key always starts with "__custom".
- [custom-tag]
- The string to be rendered as the XML tag.
- [unique-string]
- A unique string that avoids overwriting of duplicate keys in PHP arrays.
a colon character can be included within the custom-tag portion by escaping it with a backslash:
$array = [
'__custom:ns\\:custom-key:1' => [
'name' => 'Vladimir',
'nickname' => 'greeflas',
],
'__custom:ns\\:custom-key:2' => [
'name' => 'Marina',
'nickname' => 'estacet',
'tags' => [
'__custom:ns\\:tag:1' => 'first-tag',
'__custom:ns\\:tag:2' => 'second-tag',
]
],
];This will result in:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<ns:custom-key>
<name>Vladimir</name>
<nickname>greeflas</nickname>
</ns:custom-key>
<ns:custom-key>
<name>Marina</name>
<nickname>estacet</nickname>
<tags>
<ns:tag>first-tag</ns:tag>
<tns:ag>second-tag</tns:ag>
</tags>
</ns:custom-key>
</root>To set properties of the internal DOMDocument object just pass an array consisting of keys and values. For a full list of valid properties consult https://www.php.net/manual/en/class.domdocument.php.
You can use the constructor to set DOMDocument properties.
$result = ArrayToXml::convert(
$array,
$rootElement,
$replaceSpacesByUnderScoresInKeyNames,
$xmlEncoding,
$xmlVersion,
['formatOutput' => true]
);Alternatively you can use setDomProperties
$arrayToXml = new ArrayToXml($array);
$arrayToXml->setDomProperties(['formatOutput' => true]);
$result = $arrayToXml->toXml();Call $arrayToXml->prettify() method on ArrayToXml to set XML in pretty form.
Example:
$array = [
'Good guy' => [
'name' => 'Luke Skywalker',
'weapon' => 'Lightsaber'
],
'Bad guy' => [
'name' => 'Sauron',
'weapon' => 'Evil Eye'
]
];
$arrayToXml = new ArrayToXml($array);With prettification:
$arrayToXml->prettify()->toXml();will result in:
<?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>Without prettification:
$arrayToXml->toXml();will result in:
<?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>Call $arrayToXml->dropXmlDeclaration() method on ArrayToXml object to omit default XML declaration on top of the generated XML.
Example:
$root = [
'rootElementName' => 'soap:Envelope',
'_attributes' => [
'xmlns:soap' => 'http://www.w3.org/2003/05/soap-envelope/',
],
];
$array = [
'soap:Header' => [],
'soap:Body' => [
'soap:key' => 'soap:value',
],
];
$arrayToXml = new ArrayToXml($array, $root);
$result = $arrayToXml->dropXmlDeclaration()->toXml();This will result in:
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope/"><soap:Header/><soap:Body><soap:key>soap:value</soap:key></soap:Body></soap:Envelope>vendor/bin/phpunitPlease see CHANGELOG for more information what has changed recently.
