README
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>
Setting the name of the root element
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');
Handling key names
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);
Adding attributes
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>
Using reserved characters
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.
Adding attributes to the root element
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');
Using a multi-dimensional array
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>
Handling numeric keys
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()
.
Setting DOMDocument properties
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();
