PHP Variables

PHP Variables is very interesting, its just like a container. PHP Variables data transfer from one place to another place. PHP Variables start with $ sign.

Basic Example:


$a= 20;
echo $a;


Result: 20

There are two types of Variables :

  1. Pre define Variable             2. User define Variables

1) Predefined Variables : These variables are available in PHP program.  There is no need to declare and define these variable in the program. These are following  type of Pre define Variable.

Predefine Variables = Super define variables.


2) User define Variable : This variable is declare and define by developers

For Example:

$ontime is a variable and 50 is a data and this data store in variable $num. So we can use this variable for print the value of 50 at any where as per requirement.

Benefit of PHP Variable : PHP automatically converts the variable to correct data type, depending on value.


echo “First Number is $a”.”<br>”;
echo “Second Number is $b”.”<br>”;
echo “Result is $c”;

First Number is 30
Second Number is 50
Result is 80
