Data Storage in PHP

Data is stored in variables in any programing language. The variables declared in PHP are a bit different than other programing languages. Each variable name starts with "$" sign. If I like to name a variable as iknowPHP variable , it will throw an error. 

The way to declare a variable in PHP is simple though.

$iknowjava = 5;

$iknowmyjava ="Deepak";

Few points : 

1.  Variable name can start with $ only
   
2. Variable name can have only alphabets or numbers or underscore or combinatiion of these three. Spaces in variable names are not permitted

 Once done with the variables , PHP will itself decide on what variable it is , whether its a string variable , a char or a number , depending on the value it has. 

So we will move to next important part in PHP , the various operators.
