Php Redirect:
If you have moved your pages, you can use PHP to perform a redirect to your new page.
The search engine friendly way of redirecting is the 301 redirect. In PHP, this is implemented as follows:

In PHP session is used to  store  the user information on the server for later use (ex: username, password). And  this session information is temporary  storge and it’s deletd when user log out the page.
               Sessions  are created by using  a Unique Identification Number (UID) for each visitor .This helps to identify the user when their visiting on the web page.By using sessions we can increase the security to the web pages.Only authorized  user can able to acces the web page.

Start a PHP Session:

Storing a Session :

$_SESSION['session name'] = value;

Destroy a  Session:

    unset($_SESSION['session name']);

PHP has the following built in string manipulation function to replace strings:
•   str_replace
•   str_ireplace
•   preg_replace
•   strtr

•   This function replaces all occurrences of the search string with the replacement string. 
•   This function is very similar to str_replace but it is case-insensitive.
•   This function performs a regular expression search and replace.
