Learn PHP variable, Datatype And Constants in Efficient way.

In this Video, we gonna learn(shortly) about PHP variable,
DataType and Constant with Examples as it is:

the variable is used for storing values, like text
strings, numbers, or arrays.

When a variable is declared, it can be used
over and over again in your script.

The main way to store information in the middle of a PHP program is by using a variable.
Here are the most important things to know about variables in PHP.

All data stored in PHP variables fall into one of eight basic categories, known as data types. A variable’s
datatype determines what operations can be carried out on the variable ’ s data, as well as the amount of
memory needed to hold the data.

You can also define value - containers called constants in PHP. The values of constants, as their name
implies, can never be changed. Constants can be defined only once in a PHP program.

Constants differ from variables in that their names do not start with the dollar sign, but other than that
they can be named in the same way variables are. However, it’s good practice to use all-uppercase names
for constants. In addition, because constants don’t start with a dollar sign, you should avoid naming
your constants using any of PHP’s reserved words, such as statements or function names. For example,
don’t create a constant called ECHO or set type. If you do name any constants this way, PHP will get
very confused!
