1. Get data from XML Sitemap using simple_load_file() in PHP
2. Get data from XML Sitemap using file_get_contents() and SimpleXMLElement() in PHP

Lets see below examples.

Get data from XML Sitemap using simple_load_file() in PHP


                                   Simple_load_file() in PHP is used to convert XML document into an object. The below example explain retrieve data from XML Sitempa.


<?php
$xml=simplexml_load_file('http://www.phponwebsites.com/sitemap.xml');
//print_R($xml);
foreach($xml->url as $val)
 {
  echo $val->loc.' '. $val->lastmod.' '. $val->changefreq.' '. $val->priority.'<br>';
 }
?>


Get data from XML Sitemap using file_get_contents and SimpleXMLElement in PHP


                                  File_get_contents() is used to read the contents of a file into string. SimpleXMLElement is used to represents elements of XML document. The below example explain retrieve data from XML Sitemap.

 {
  echo $val->loc.' '. $val->lastmod.' '. $val->changefreq.' '. $val->priority.'<br>';
 }
?>


 When you give print_R() in above PHP file, you can see the output on screen like below.


 SimpleXMLElement Object (
   [url] => Array (
         [0] => SimpleXMLElement Object (
       [loc] => http://www.phponwebsites.com/p/php.html
           [lastmod] => 2014-07-26
       [changefreq] => daily
       [priority] => 1 )
 [1] => SimpleXMLElement Object (
       [loc] => http://www.phponwebsites.com/p/mysql.html
       [lastmod] => 2014-07-26
       [changefreq] => daily
       [priority] => 1 )
 [2] => SimpleXMLElement Object (
       [loc] => http://www.phponwebsites.com/p/htaccess.html

Create XML file using PHP and MySQL

                                   You can get output as XML format using PHP. You can import values to XML file from Mysql database using PHP.

                                   XML expands Extensible Markup Language. It is used to share your data across various platforms. You can also retrieve values from XML file using PHP.

Get output as XML format using PHP


                                    If you want to convert your Mysql table values into XML format using PHP, then follow below steps.


Step1: Add header to XML file in PHP


                                    First you need to add content type of XML file in PHP in order to get output as XML format. It need to add below PHP codes in your PHP file.

header ("content-type: text/xml");

Step2: Connect mysql database


                                    After added content type of XML, you need to connect Mysql database using PHP to retrieve values from it. You add below codes after content type in PHP file.

mysql_connect('localhost','root','');
mysql_select_db('fitness');

Step3: Add content to XML file


                                  Then select required values from Mysql database using mysql_query(). Retrieve values from query result using mysql_fetch_array. Finally your PHP file look likes below one.


<?php
header ("content-type: text/xml");
mysql_connect('localhost','root','') or die(mysql_error());
mysql_select_db('fitness') or die(mysql_error());
$xml='<?xml version="1.0" encoding="UTF-8"?>';
$qr=mysql_query("SELECT * FROM `f_img` order by id desc") or die(mysql_error());
$xml.='<userlist>';
while($res=mysql_fetch_array($qr))
{
 $xml.='<user><name>'.$res['name'].'</name><state>'.$res['state'].'</state><country>'.$res['country'].'</country></user>';
}
$xml.='</userlist>';
echo $xml;
?>


                                 You will get output as XML format like below,

<userlist>
    <user>
       <name>Clark</name>
       <state>California</state>
       <country>USA</country>
   </user>
   <user>
      <name>Smith</name>
      <state>London</state>
      <country>United Kingdom</country>
   </user>
   <user>
      <name>Nathan</name>
      <state>Franche Comte</state>
      <country>France</country>
   </user>
   <user>
      <name>Nastya</name>
      <state>Moscow</state>
      <country>Russia</country>
   </user>
</userlist>

                                     Now you got output as XML content. Similarly, you can get XML element's values using PHP.

Create json file using PHP and MySQL

                        You can create json file using PHP and Mysql. You can get output as json format using PHP and Mysql. Before you want to know that, first you should know what is json? and what is the us of json?

JSON

      
                       JSON expands JavaScript Object Notation. It is one of the data interchange format. You can easily read and write data through JSON file.
                       It is language independent. So you can retrieve data from it using any familiar languages like PHP. It should be array format, object format and both array and object fotmat.
     The array format of Json file should be like this,

       [    
           {
              'tutorial':'PHP',
              'link':'http://www.phponwebsites.com/p/php.html'
           },
           {
              'tutorial':'Mysql',
              'link':'http://www.phponwebsites.com/p/mysql.html'
           },
           {
            'tutorial':'htaccess',
            'link':'http://www.phponwebsites.com/p/htaccess.html'
           }    
      ]

The object of JSON should be like this,

    {  
           'tutorial':'PHP',
            'link':'http://www.phponwebsites.com/p/php.html'  
    }

Get output as json format using PHP and Mysql


                           Now you know something about JSON files. So we are going to know how to get output as JSON format using php and mysql.

Add header to create json file using PHP and Mysql

       
                          If you want to create json file, then you have to add header for json file. It is like below

header('Content-Type: application/json'); 

          Where json indicate this is json file

Add content to json file using PHP


             Then you need to add contents to your json file as you want as. Retrieve values from query result using mysql_fetch_arraySuppose you have more values in a variable. Then you need to store all values in array. Consider the following PHP code.

<?php
header('Content-Type: application/json');
$linklist=array();
$link=array();
mysql_connect('localhost','root','') or die(mysql_error());
mysql_select_db('quicksai_quick') or die(mysql_error());
$qr=mysql_query("SELECT * FROM `links` ") or die(mysql_error());
while($res=mysql_fetch_array($qr))
{
 $link['tutorial']=$res['tutorial'];
 $link['url']=$res['url'];
 array_push($linklist,$link);
}
//print_R($linklist);
echo json_encode($linklist);
?>

      The above example explain how to create json file on multidimensional array using PHP and Mysql.
     where,
               array() - create array variable.
               array_push() - insert values into array
               json_encode() - encode the values and returns JSON representation of values
             

The above example will give output as json file. It should be like this:
      
      [
      {'tutorial':'PHP', 'link':'http://www.phponwebsites.com/p/php.html'},
      {'tutorial':'Mysql', 'link':'http://www.phponwebsites.com/p/mysql.html'},
      {'tutorial':'htaccess','link':'http://www.phponwebsites.com/p/htaccess.html'}
      ]

 where new is database name

                Use new

The above query is used to use database "new".
                  The MySQL query for create table is,

                Create table links (id int not null auto_increment primary key, name varchar(200), link varchar(200), description varchar(250))

                 Now the table "links" is created. Then store values into table using below query

                insert into table links values('','PHP','http://www.phponwebsites.com/p/php.html','PHP doubts are clarified at Phponwebsites')

                After insert values into table, your table look likes below

insert values into MySQL table for RSS Feed


2. Add header type RSS Feed


                            First you need to add content type of RSS feed. It is represented below.

header("Content-Type: application/rss+xml; charset=ISO-8859-1");


3. Add content to RSS Feed

                         
                            First of all you need to store all links in your database. Then on;y you can retrieve it using PHP. The below example we Retrieve data from MySQL database using mysql_fetch_array in PHP.
After added header, you have to add some name spaces for RSS Feed. Finally add contents to RSS Feed.


<?php
header("Content-Type: application/rss+xml; charset=ISO-8859-1");
echo '<?xml version="1.0" encoding="UTF-8" ?>
<?xml-stylesheet type="text/xsl" media="screen" href="/~d/styles/rss2full.xsl"?>

       $connection = @mysql_connect('localhost', 'root', '') or die(mysql_error());
       mysql_select_db('new')  or die (mysql_error());
       $query = "SELECT * FROM links order by id desc";
       $rss = mysql_query($query) or die (mysql_error());
       $ImgPath='http://2.bp.blogspot.com/-vwl4cGyoDPM/UqKklyTGE-I/AAAAAAAAALI/iOipE7-PhAM/s1600/logo5.png';
       while($row=mysql_fetch_array($rss)){
       echo '
<item>
<title>'.$row['name'].'</title>
<link>'.$row['link'].'</link>
<content:encoded>
      <![CDATA[<p align="left">
          <a href="'.$row['link'].'"><img style="background-image: none; " border="0" src="'.$ImgPath.'" />    </a></p>]]>
       </content:encoded>
       <description>'.$row['description'].'</description></item>';
}
      echo '</channel>
</rss>';

    font-size: 17px;

}


3. Add javascript for form validation


                                 Then you've to validate your form using javascript. You can validate empty textbox, validate valid email id and valid phone number using below javascript.

$(document).ready(function() {
$('#submit').click(function() {
var name=document.getElementById('name').value;
var phone=document.getElementById('phone').value;
var mail=document.getElementById('mail').value;
var message=document.getElementById('message').value;
var ph = /^([0-9-+]+)$/;
var chk = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
if(name=='')
{
 $('#er').html('Enter your name');
 return false;
}
if(phone=='')
{
 $('#er').html('Enter your phone number');
 return false;
}
if(!ph.test(phone) || phone.length!=10)
{
 $('#er').html('Enter valid phone number');
 return false;
}
if(mail=='')
{
 $('#er').html('Enter your mail');
 return false;
}
if(!chk.test(mail))
{
 $('#er').html('Enter valid email');
 return false;
}
if(message=='')
{
 $('#er').html('Enter your message');
 return false;
}
});

});

4. Send mail using PHP


                                   After designed HTML form, you need to get user details and send it to website owner using PHP mail(). Visit How to send mail using PHP. Let see below PHP script for send mail.

if(isset($_POST['submit']))
 {
  $name=$_POST['name'];
  $phone=$_POST['phone'];
  $mail=$_POST['mail'];
  $message=$_POST['message'];
  $to='guruparthiban19@gmail.com';
  $header='From: '.$mail;
  $subject=$name.' contacts you';
  $body="Name: ".$name."\n";
  $body.="Phone: ".$phone."\n";
  $body.="Email: ".$email."\n";
  $body="He/She says ".$message."\n";
  $m=mail($to,$subject,$body,$subject);
  if($m)
  {
   echo"<script>Message send successfully</script>";
  }
  else
  {
   $er="Message not sent";
  }
 }
