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>
