Variables in PHP

A variable is a storage area. You put things into your storage areas (variables) so that you can use and manipulate them in your programmers. Things you'll want to store are numbers and text.

Variable in PHP

You can't begin their names with an underscore (_), or a number. But most other characters are fine.

Example 1 :

A person is going to be collecting the books. But we can specify how many books he will be collecting. If you have five books  to give him, then you do the "Answer"  is like this:

Answer is = 5 Books

Ok, now going to the subject …

 you're studying  PHP, so there's something missing. Two things, actually. First, your people (variables) need a dollar sign at the beginning (people are like that). So it would be this:

$books = 10

Examples 2 : try to do

$books=10+20+30;

What is your answer : answer must be 60

Example 3 : Test your mind

Find the total books ?

$english_book=10;

$maths_book=5;

So, then we can proof this 

$total_book=$english_book+maths_book;

Out put is15

In the next part, we'll take a look at how to use String types.
