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("neveropen"));            $root -> appendChild($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:

  
  

  
  
  

  <neveropen>     <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> </neveropen>
