                     VARIABLES IN PHP

                     A variable is a memory location that is used to store a value. When a variable is created, some
                     space is allocated in memory for it. This memory space is referred by the name that we give to an

                     identifier. A variable name must start with a $ (dollar) sign. For example,

                     <?php

                     $age = 12;
                     $name = "Divya";

                     $address = "12A, Stree No-4, Govindpuri";

                     $section = 'C';
                     ?>

                     Here 12, "Divya", "12A, Stree No-4, Govindpuri" and 'C' are the values assigned to variables
                     named age, name, address and section respectively. The = (equal) operator is used to assign
                     a value to a variable. Let us create a web page to show the use of variables. Type the following
                     code in notepad:

                     <HTML>
                     <HEAD> <TITLE> Using Variables </TITLE> </HEAD>

                     <BODY>

                     <?php
                     $name = "Divya";

                     echo "Welcome ", $name;

                     ?>
                     </BODY>

                     </HTML>

                                                                                                     Techipedia (PHP)  137
