PHP SimpleXML: Create an XML Document

PHP Version: PHP3, PHP4, PHP5

Description

In This tutorial, I will be covering how to create an well-formed XML document from a HTML form. In this example, I have created a html page to enter employee details and the data entered by user is stored in an xml file.

Example of Html Page

UI of html page I have created as below.

Example of Html script

The html script got the above page is as below.

<html>

<head>

<title>Employee Data</title>

</head>

<body>

<p>Employee Data</p>

<form method="POST" action="php/employee.php">

<input type="hidden" name="create_employee" value="true">

<table>          

  <tr>

    <td width="27%">Employee Name:</td>

    <td width="73%"><input type="text" name="empName" size="20"></td>

  </tr>

  <tr>

    <td width="27%">Employee Address</td>

    <td width="73%"><input type="text" name="empAddress" size="73"></td>

  </tr>

  <tr>

    <td width="27%">Employee SSN</td>

    <td width="73%"><input type="text" name="empSSN" size="20"></td>

  </tr>

  <tr>

    <td width="27%">Company Name</td>

    <td width="73%"><input type="text" name="empCompany" size="73"></td>

  </tr>

  <tr>

    <td width="27%">XML File Name</td>

    <td width="73%"><input type="text" name="xmlfileName" size="20"></td>

  </tr>

</table>

  <p align="center">

  <input type="submit" value="Submit" name="B1"></p>

</form>

</body>

</html>

Example of PHP usage to create xml file

In the above employee form, on submit the data will be posted on php/employee.php file. In employee.php file, I have gathered all POSTED data as below:

if(isset($_POST['create_employee'])){

        echo "Employee Data Posted";

        $xmlfileName = $_POST['xmlfileName'];

        $empName = $_POST['empName'];

        $empAddress = $_POST['empAddress'];

        $empSSN = $_POST['empSSN'];

        $empCompany = $_POST['empCompany'];

        $xml_dec = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>";

After gathering all data from the form then, I created a variable to hold all the data entered by user in string format.

        $rootELementStart = "<employee>";

        $rootElementEnd = "</employee>";

        $xml_doc=  $xml_dec;

        $xml_doc .=  $rootELementStart;

        $xml_doc .=  "<employeename>";

        $xml_doc .=  $empName;

        $xml_doc .=  "</employeename>";

        $xml_doc .=  "<employeeaddress>";

        $xml_doc .=  $empAddress;

        $xml_doc .=  "</employeeaddress>";

        $xml_doc .=  "<SSN>";

        $xml_doc .=  $empSSN;

        $xml_doc .=  "</SSN>";

        $xml_doc .=  "<company>";

        $xml_doc .=  $empCompany;

        $xml_doc .=  "</company>";

        $xml_doc .=  $rootElementEnd;

        $default_dir = "xml_files/";

        $default_dir .=   $xmlfileName .".xml";

Here I have taken default directory as xml_file directory.

After creating string representation of employee data, I have used following PHP script to store in the file

$fp = fopen($default_dir,'w');

            $write = fwrite($fp,$xml_doc);

fopen function opens file or URL. I assume that xml_file directory is there so I have checked for error during fopen function call.

I have used fwrite($fp,$xml_doc); to store the xml string into a file.

Output

<?xml version="1.0" encoding="UTF-8"?>

<employee>

            <employeename>Markwilson</employeename>

            <employeeaddress>Topxml</employeeaddress>

            <SSN>12345</SSN>

            <company>TopXML</company>

</employee>
