Variables in PHP declared with $ symbol immediately
followed by alphabets or underscore. We can use variables
without declaring also. But if we are accessing one
variable without assigning values, then we will get warning
messages.
For example
<?php
$a=10;
if($a==2)
$b=20;
echo $b;
?>
This will throw warning messages.
