Given a multi-dimensional array and the task is to convert this array into an XML file. To converting the multi-dimensional array into an xml file, create an XML file and use appendChild() and createElement() function to add array element into XML file. Example:
  • First, create a PHP Multidimensional Array for converting that array into the XML file format. php 
    $array = array (
    'company' => 'Gfg',
    'employe' => array (
        '0' => array (
            'name' => 'Jatin Das',
            'age' => '34'
        ),
        '1' => array (
            'name' => 'Mohit Mal',
            'age' => '30'
        ),
        '2' => array (
            'name' => 'Shubham Jha',
            'age' => '24'
        ),
        '3' => array (
            'name' => 'Harsha Bhosle',
            'age' => '29'
        )
    )
);
  • Now, you need to create a user-defined function generatXML(). php 
    function generateXML($data) {
    
    $title = $data['company'];
    $rowCount = count($data['employe']);
 
    // Create the xml document
    $xmlDoc = new DOMDocument();
 
    $root = $xmlDoc -> appendChild($xmlDoc ->
                            createElement("geeks"));
    
    $root -> appendChild($xmlDoc -> 
                        createElement("title", $title));
    $root -> appendChild($xmlDoc -> 
                  createElement("totalRows", $rowCount));
    
    $tabUsers = $root -> appendChild($xmlDoc ->
                            createElement('rows'));
 
    foreach($data['employe'] as $user) {
        if (!empty($user)) {
            $tabUser = $tabUsers -> appendChild($xmlDoc -> 
                                   createElement('employe'));
            foreach($user as $key => $val) {
                $tabUser -> appendChild($xmlDoc ->
                                  createElement($key, $val));
            }
        }
    }
 
    header("Content-Type: text/plain");
 
    // Make the output
    $xmlDoc -> formatOutput = true;
 
    // Save xml file
    $file_name = str_replace(' ', '_', $title) . '.xml';
    
    $xmlDoc -> save($file_name);
 
    // Return xml file name
    return $file_name;
}
  • Then use generateXML() function and pass array data in it to convert the array to XML in PHP. php 
    generateXML($array);
  • Output: html 
    <geeks>
    <title>Gfg</title>
    <totalRows>4</totalRows>
    <rows>
        <employe>
            <name>Jatin Das</name>
            <age>34</age>
        </employe>
        <employe>
            <name>Mohit Mal</name>
            <age>30</age>
        </employe>
        <employe>
            <name>Shubham Jha</name>
            <age>24</age>
        </employe>
        <employe>
            <name>Harsha Bhosle</name>
            <age>29</age>
        </employe>
    </rows>
</geeks>
