Table: user

In order to execute the query in PHP,  we create a where.php. The Where.php uses the mysql_query () function. This function helps you to send the query or command to a MySQL connection. The Mysql_query () function create a mysql query "SELECT * FROM user WHERE fname='sandeep'", which select all the records from "user" where fname= "sandeep". The While loop tells PHP to execute the statement repeatedly, till the while expression evaluate all the records of 'sandeep' from table 'user'. The echo , property of PHP is used to print the records on the browser.
