How to create and read the xml using php

XML is very important in in today’s application development environment.
If you’ve never before worked with XML in PHP or have not yet made the jump to PHP5, this starter guide to working with new functionality available in PHP5 for XML.

Using following code you are able to create simple xml file.

01<?php
02 
03//Creates XML string and XML document using the DOM
04$dom = new DomDocument('1.0');
05 
06//add root - <books>
07$books = $dom->appendChild($dom->createElement('books'));
08 
09//add <book> element to <books>
10$book = $books->appendChild($dom->createElement('book'));
11 
12//add <title> element to <book>
13$title = $book->appendChild($dom->createElement('title'));
14 
15//add <title> text node element to <title>
16$title->appendChild(
17$dom->createTextNode('Wordpressapi Magazine'));
18 
19//generate xml
20$dom->formatOutput = true; // set the formatOutput attribute of
21// domDocument to true
22// save XML as string or file
23$test1 = $dom->saveXML(); // put string in test1
24$dom->save('wordpressapi1.xml'); // save as file
25?>

Out put of above code will as follows:

1<?xml version="1.0"?>
2<books>
3<book>
4<title>Wordpressapi Magazine</title>
5</book>
6</books>

Now I am going to show you how to read the xml file using php

[/php]
loadXML(‘wordpressapi1.xml’);
if (!$dom) {
echo ‘Error while parsing the document’;
exit;
}

$s = simplexml_import_dom($dom);

echo $s->book[0]->title; // WordPressapi Magazine
?>
[/php]

or in other way

1$xmlFileData = file_get_contents(“wordpressapi1.xml”);
2// Here's our Simple XML parser!
3$xmlData = new SimpleXMLElement($xmlFileData);
4// output will be shown in array format
5print_r($xmlData);
