Variables in PHP
Variables are nothing but identifiers to the memory location to store data. We can create any number of varibles. In PHP all the variables begin with a dollar sign "$" and the value can be assignes using the "=" operator as shown below: Another important thing in PHP is that all the statements must end with a semicolon ";". In PHP we needn't have to specify the variable type, as it takes the data type of the assigned value. From the above example we understand that '$Name' is of Data type String and '$Age' is of type Numeric.Visit publisher site: Variables in PHP
