Create XML file with PHP 5 and MySQL

In this tutorial i would like to explain that how to create XML files in PHP 5 after extracting data from the MySQL database.

In this code there is no hard coded node for the XML files , The data is retrived from the database as an associative and transformed to the XML files.

Requirement

There should be DOM extension available in PHP installation.

Code Sample

Let's discuss how many step is here to write this code, there are three step to write the code

(i) Connection from MySQL databse.
(ii) Retrieve data from the database tables.
(iii) Write retrieved data in XML files.

Connection from MySQL databse

$con=mysql_connect('localhost' , 'testuser' , 'pass123');

if( $con)
{
echo "could not connect host 'localhost' . ";
exit();
}
if (!mysql_select_db('demo'))
{
echo "Cannot connect to database 'demo' . ";
exit();

Above script connect with database 'demo' and now we can fetch the data from this database tables.

Retrieve data from the database tables

$query = "SELECT * FROM tablename ";
$result = mysql_query ($query , $con);

Now we have a data amd need to write it in XML format.

Write retrieved data in XML files

Create new XML document

$document= new DOMDocument( '1.0' );

The first element we create in the XML document is known as the root element. Each XML document must have 1 root element.

Create root node

$rootnode = $document->createElement('root');
$rootnode = $document->appendChild($rootnode );

Now after creating the root node we have to add the data from the database


while($row = mysql_fetch_assoc($result))
{
$node= $document->createElementNS( 'Item', 'ezobject:object-relation-list' );
$node = $rootnode->appendChild($node);

foreach ($row as $fieldname => $fieldvalue)
{
$child = $document->createElement($fieldname);
$child = $node ->appendChild($child);

$nodevalue = $document->createTextNode($fieldvalue);
$nodevalue = $child->appendChild($nodevalue);
}
}
$xml_doc = $document->saveXML();

echo $xml_doc;

The above tutorial help you to create XML file in PHP 5.

PHP and AJAX

In this article i would like to explain little bit about AJAX and how it works with PHP.

What is AJAX?

AJAX(Asynchronus JavaScript and XML) is based on JavaScript and HTTP Request.

With AJAX JavaScript can communicate directly with the server, with theXMLHttpRequestobject. With this object, a JavaScript can fetch data with a web server without reloading the page.

AJAX uses asynchronous data transfer (HTTP requests) between the browser and the web server, allowing web pages to request requried data(information) from the server instead of whole pages.

What is HTTP Request ?

HTTP (Hypertext Transfer Protocol) is a request/response protocol,Whenever web browser fetches a page (date) from a web server, it does so using HTTP. This means your web browser sends a request for some data and the web server sends back a response using the HTTP.

What is XMLHttpRequest ?

XMLHttpRequest is a JavaScript object that was designed by Microsoft,The XMLHttpRequest object provides a way to communicate with a server after a web page has loaded, it's support all the major browaer like Internet Explorer, Firefox, safari.

After explaining the above important terms let see how PHP works with the AJAX

PHP and AJAX :

working with PHP and Ajax is very simple

Step I: we need to know how to create an XMLHTTPRequest object. The process differs slightly depending on whether you are using Internet Explorer (5+) with ActiveX enabled, or a standards-compliant browser such as Mozilla Firefox.

With IE5 and IE6 , the request like:

http = new ActiveXObject("Microsoft.XMLHTTP");

With IE7+, Firefox, Chrome, Opera, Safari.we can instantiate the object directly like:

http = new XMLHttpRequest();

Step 2: We need to write an event handler which will be called via some event on our page, and will handle sending our request for data to our server.

The event handler will use various methods of our XMLHTTPRequest object to:

(i) make the request of the server

(ii) check when the server says that it has completed the request

(iii) deal with the information returned by the server

using above two step you can write PHP application using AJAX.

MySQL Event Scheduler

MySQL 5.1 Event Scheduler, Conceptually, this is similar to the idea of the UNIX crontab (also known as a “cron job”) or the Windows Task Scheduler.

What is “Event Scheduler” event is an object whose statements are executed in response to the passage of a specified time interval. An event performs a specific action according to a schedule. An event’s timing can be either on-time or recurrent. A one-time event executes one time only. A recurrent event repeats its action at a regular time interval.

Events are executed by a special event scheduler thread; when we refer to the Event Scheduler, we actually refer to this thread. When running, the event scheduler thread and its current state can be seen by users having the PROCESS privilege in the output of SHOW PROCESSLIST

* MySQL 5.1.12 and later, an event are uniquely identified by its name and the schema to which it is assigned.

Let’s see how to create Event in MySQL 5.1:

Step I: You need in Install MySQL 5.1

Download MySQL 5.1 from URL http://dev.mysql.com/downloads/mysql/5.1.html#winx64 For windows

Follow simple Installer step according to Installation.doc;

Step II: Create database in MySQL Server.

I did the following necessary steps To Run the Scheduler:

(i) Goto Start>All programs>MySQL>MySQL 5.1 server> MySQL command Line Client

(ii) mysql> SET GLOBAL EVENT_SCHEDULER=ON;

(iii ) Create event writing simple statement on MySQL Command Line
mysql > CREATE EVENT purge_Data
ON SCHEDULE AT ‘2008-07-20 23: 59:00’
BEGIN
INSERT INTO archive_news_article select *from news_article where pubdate <>

and then press enter, Above event scheduler execute on ‘2008-07-20 23: 59:00’ only one time and purge data from news_article table to archive_news_article table. Let me Explain the recurrent event scheduler with an Example Let’s apply on same schema if we want to purge starts from a particular Date Time in every month end .

(iii) mysql> SET GLOBAL EVENT_SCHEDULER=ON;

(iii ) Create event writing simple statement on MySQL Command Line

mysql > CREATE EVENT purge_everymonth
ON SCHEDULE EVERY 1 MONTHSTARTS '2008-07-29 23:00:00' + interval 0 minute
DO
BEGIN
INSERT INTO archive_news_article select *from news_article where pubdate <>
END ;

and then press enter, Above event scheduler execute star t on ‘2008-07-20 23: 59:00’ and purge data from news_article table to archive_news_article table and then it execute every 1 month. At the 23: 59:00’ .

When a scheduled event is no longer wanted or needed, it can be deleted from the server by its definer using the DROP EVENT statement. Again go to Mysql command line:

Mysql> Drop Event purge_everymonth;

Important
It is possible to set the Event Scheduler to DISABLED only at server startup. If event_scheduler is ON or OFF, you cannot set it to DISABLED at runtime. Also, if the Event Scheduler is set to DISABLED at startup, you cannot change the value of event_scheduler at runtime.

and then click on the 'Private Browsing' and the the tab open like this..

and then i started 'Private Browsing'.

The program title bar does state that you're using Private Browsing, but there's no blatant icon like other Browser. see below that only the title bar state that 'Private Browsing' there is no any icon on blatant icon.
