php is a loosely typed language i.e without declaring a
variable we can use that,in this variable defined by using $

Answer / master
ya i agree with priyanka, as she said in php variables r
loosely typed in the sense that , for example if u r wrking
in c and u want to assign int value to a variable then it
is done as int x=3; but in case of php the values r not
assigned along with the data type like int $x=3; (same as
above) instead its only $x=3; and the php parser
understands that it is int type and works accordingly.
hope u guys got it!!!

Answer / muthu
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.
