<?php
header("Content-Type: application/vnd.ms-excel");
header("Content-disposition: attachment; filename=spreadsheet.xls");
mysql_connect('localhost','root','') or die(mysql_error());
mysql_select_db('new') or die(mysql_error());
$q=mysql_query("select * from table1")  or die(mysql_error());
if(mysql_num_rows($q)>0)
{
echo"<table><tr><th>Name</th><th>Address</th><th>Phone</th></tr>";
 while($res=mysql_fetch_array($q))
 {
  echo"<tr><td>".$res['name']."</td><td>".$res['address']."</td><td>".$res['phone']."</td></tr>";
 }
echo"</table>";
}
?>

     Where,
                 mysql_fetch_array() return values as both an associative and numeric array.

login.php:


<html>
<head>
<style type="text/css">
 input{
 border:1px solid olive;
 border-radius:5px;
 }
 h1{
  color:darkgreen;
  font-size:22px;
  text-align:center;
 }
span{
  color:lightgreen;

 }
</style>
</head>
<body>
<h1>Login<h1>
<form action='#' method='post'>
<table cellspacing='5' align='center'>
<tr><td>User name:</td><td><input type='text' name='name'/></td></tr>
<tr><td>Password:</td><td><input type='password' name='pwd'/></td></tr>
<tr><td></td><td><input type='checkbox' name='remember' /> <span>Remember me</span></td></tr>
<tr><td></td><td><input type='submit' name='submit' value='Submit'/></td></tr>
</table>

</form>
<?php
session_start();
//your values are stored in cookies, then you can login without validate
if(isset($_COOKIE['name']) && isset($_COOKIE['pwd']))
{
    header('location:welcome.php');
}
// login validation in php
if(isset($_POST['submit']))
{
 mysql_connect('localhost','root','') or die(mysql_error());
 mysql_select_db('new') or die(mysql_error());
 $name=$_POST['name'];
 $pwd=$_POST['pwd'];
 if($name!=''&&$pwd!='')
 {
   $query=mysql_query("select * from login where name='".$name."' and password='".$pwd."' ");
   $res=mysql_fetch_row($query);
   if($res)
   {
    if(isset($_POST['remember']))
{
 setcookie('name',$name, time() + (60*60*24*1));
 setcookie('pwd',$pwd, time() + (60*60*24*1));
}
    $_SESSION['name']=$name;
    header('location:welcome.php');
   }
   else
   {
    echo'You entered username or password is incorrect';
   }
 }
 else
 {
  echo'Enter both username and password';
 }
}
?>
</body>
</html>

             where,
            if(isset($_COOKIE['name']) && isset($_COOKIE['pwd'])) {} means if the user values in  cookies, then the user can login directly without login validation in php.
         
           if(isset($_POST['remember'])){
           setcookie('name',$name,time() + (60*60*24*1));
           setcookie('pwd',$pwd,time() + (60*60*24*1));
           }
           which means, if the user click the remember me check box, then you have to store them in cookie. If you don't know  about cookies in php, then visit Cookies in php.

          When you run the login.php fille, you'll get output like this:

validate remember me concept in login form using php

welcome.php:


<?php    
  session_start();
  if(isset($_COOKIE['name']))
  {
    echo 'Welcome: '. $_COOKIE['name'].'<br>';
  }
  else
  {
    echo 'Welcome: '. $_SESSION['name'].'<br>';
  }
  echo'<a href="signout.php">Singout</a>';
?>

      where,
                  if(isset($_COOKIE['name'])){}else{} means if the values in cookie, then return name from cookie. Otherwise name return from session.
             Now you enter username and password  'guru' and 'guru' without select the remember check box, you will navigate to 'welcome.php' page and get output like this:

                   welcome: guru
                   Signout

 If it is wrong, then you can't login.

   

Signout in php:           


            When you click the signout.php, it destroy the session and return back to login page. The php script for signout page:
signout.php:

<?php    
         session_start();
         session_destroy();
         header('location:login.php');
?>

           You select the remember me check box while login. Then you navigate to welcome.php page. Now you click the signout on welcome.php page, you can't return back to login page. Because the concept is, when you signout the page, you return back to login.php page, where you wrote the php script as like as:
          
                  if(isset($_COOKIE['name']) && isset($_COOKIE['pwd'])) {}

It means, if values in cookie, you can login again. Now you comes to login page and again login and navigates to welcome page because your values in cookies.So you are in welcome page until the cookie is expired.

<h1>Login<h1>

                         Sitemap is very important for all websites. All of you know, the search engines like google, bing are crawling pages on your websites to know about websites. Using this sitemap, webmasters to inform search engines about pages for crawling. Sitemap is a XML file which contains all url of your websites upto to date. If you add new page to your site, then you'll add url of new page to sitemap for crawling.

                          Sitemap is also provide url structure of websites. Suppose a new user comes to your websites. The sitemap leads new user to all pages on your site.

Structure of sitemap: 


                    The structure of sitemap is:

<?xml version="1.0" encoding="UTF-8">
 <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9
 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">
  <url>
    <loc>http://www.phponwebsites.com</loc>
<lastmod>today date<lastmod>
<changefreq>daily</changefreq>
<priority>1</priority>
  </url>
  <url>
    <loc>http://www.phponwebsites.com/p/htaccess.html</loc>
<lastmod>today date<lastmod>
<changefreq>daily</changefreq>
<priority>1</priority>
  </url>
 </urlset>

  where,
      urlset - encapsulates the file ie, start sitemap
      url - parent tag for each entry ie, each page
      loc - location of url
      lastmod - date for last modification of file
      changefreq -  how frequently the pag is changed. It should be always, hourly, daily, monthly, weekly, yearly, never
      priority - priority of url. It should be between 0.0 to 1.0

Create sitemap dynamically using PHP and MySQL:


                          First you need to add content type for xml to generate sitemap in PHP. ie,

 header ("content-type: text/xml");


                        Then add contents to XML file. Then save this file as sitemap.php .


<?php
 mysql_connect('localhost','root','') or die(mysql_error());
 mysql_select_db('new') or die(mysql_error());
 $dat=date('Y-m-d');
 header ("content-type: text/xml");
 echo '<?xml version="1.0" encoding="UTF-8"?>
 <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9
 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">';
 $urls=mysql_query("select * from url")or die(mysql_error());
 while($row_Tags=mysql_fetch_array($urls))
 {
   echo "<url><loc>".$row_Tags['url']."</loc><lastmod>".$dat."</lastmod><changefreq>daily</changefreq><priority>1</priority></url>";
 }
  echo "</urlset>";
 ?>


.htaccess:

               
               In your .htaccess, you add following codes.

RewriteRule ^sitemap.xml sitemap.php [L]

                   When you run sitemap.xml on your website each time,  it display upto date contents.
