The PHP function presented in this page can be used to convert XML content to JSON string. The XMLtoJSON() function receives the URL address of the XML file. Returns a string with the JSON object.
• This function cannot be used with XML content with Namespace.

Code of XMLtoJSON()

// converts XML content to JSON
// receives the URL address of the XML file. Returns a string with the JSON object
function XMLtoJSON($xml) {
  $xml = file_get_contents($xml);    // gets XML content from file
  $xml = str_replace(array("\n", "\r", "\t"), '', $xml);    // removes newlines, returns and tabs

  // replace double quotes with single quotes, to ensure the simple XML function can parse the XML
  $xml = trim(str_replace('"', "'", $xml));
  $simpleXml = simplexml_load_string($xml);

  return stripslashes(json_encode($simpleXml));    // returns a string with JSON object
}
- Just add the XMLtoJSON() function in you PHP file, and call it passing the URL address of the XML file.

- If you want to convert XML content stored into a string, delete or comment this line of code:
$xml = file_get_contents($xml);
And call the XMLtoJSON() function passing the string with the XML content.
$strxml = 'xml content';
$strjson = XMLtoJSON($strxml);
• This function can also be used to easily convert XML content to Array. Just call the function to get the string with JSON object, then apply the json_decode() to convert the JSON string to Array.
$strjson = XMLtoJSON($xml);
$arrjson = json_decode($strjson, true);

function XMLtoJSON($xml) {
  $xml_cnt = file_get_contents($xml);    // gets XML content from file
  $xml_cnt = str_replace(array("\n", "\r", "\t"), '', $xml_cnt);    // removes newlines, returns and tabs

  // replace double quotes with single quotes, to ensure the simple XML function can parse the XML
  $xml_cnt = trim(str_replace('"', "'", $xml_cnt));
  $simpleXml = simplexml_load_string($xml_cnt);

  return json_encode($simpleXml);    // returns a string with JSON object
