Let’s get started.


Create an Application

Create a folder php-xml in your localhost directory.

Case #1

In this case we assume that XML data is written into a separate file.

Inside this folder, create a file called index.php.

Suppose we have a XML file as students.xml

<?xml version='1.0' standalone='yes'?>
<students>
    <student>
      <rollNo>2</rollNo>
      <name>Sanjay Kumar</name>
      <gender>Male</gender>
      <subjects>
         <subject>English</subject>
         <subject>Hindi</subject>
         <subject>Physics</subject>
      </subjects>
    </student>
    <student>
      <rollNo>5</rollNo>
      <name>Vijay Kumar</name>
      <gender>Male</gender>
      <subjects>
         <subject>Hindi</subject>
         <subject>Physics</subject>
      </subjects>
    </student>
    <student>
      <rollNo>6</rollNo>
      <name>Ashish Kumar</name>
      <gender>Male</gender>
      <subjects>
         <subject>English</subject>
         <subject>Hindi</subject>
      </subjects>
    </student>
    <student>
      <rollNo>10</rollNo>
      <name>Dhananjay Negi</name>
      <gender>Male</gender>
      <subjects>
         <subject>English</subject>
         <subject>Hindi</subject>
         <subject>Physics</subject>
      </subjects>
    </student>
</students>

Open index.php and write this complete code into it.

<?php   

$xml = simplexml_load_string(file_get_contents("students.xml"));
// convert the XML string to JSON
$jsonData = json_encode($xml, JSON_PRETTY_PRINT); 

echo '<pre>';
print_r($jsonData);

?>

Case #2

This is the case where we assume XML data into php file.

<?php   
$xml_string =  <<<XML
<?xml version='1.0' standalone='yes'?>
<students>
    <student>
      <rollNo>2</rollNo>
      <name>Sanjay Kumar</name>
      <gender>Male</gender>
      <subjects>
         <subject>English</subject>
         <subject>Hindi</subject>
         <subject>Physics</subject>
      </subjects>
    </student>
    <student>
      <rollNo>5</rollNo>
      <name>Vijay Kumar</name>
      <gender>Male</gender>
      <subjects>
         <subject>Hindi</subject>
         <subject>Physics</subject>
      </subjects>
    </student>
    <student>
      <rollNo>6</rollNo>
      <name>Ashish Kumar</name>
      <gender>Male</gender>
      <subjects>
         <subject>English</subject>
         <subject>Hindi</subject>
      </subjects>
    </student>
    <student>
      <rollNo>10</rollNo>
      <name>Dhananjay Negi</name>
      <gender>Male</gender>
      <subjects>
         <subject>English</subject>
         <subject>Hindi</subject>
         <subject>Physics</subject>
      </subjects>
    </student>
</students>
XML;

$xml = simplexml_load_string($xml_string);
// convert the XML string to JSON
$jsonData = json_encode($xml, JSON_PRETTY_PRINT); 

echo '<pre>';
print_r($jsonData);

?>
