Convert multidimensional array to XML file in PHP

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.

  $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().

  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.

  generateXML($array);
• Output:

  <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>
