In programming you use the if / else a lot
most of the programs are, if this is a fruite, then you can eat it, if it is not a fruit, then don't eat it
Or if the price is correct, show the picture, if not then go to another page, things like that
Let's see a little program with the if / else statement.
First you have a variable. $var = "25"
Then you have the "if" and the ( );
Inside the parenthesis you make your comparison, if "this" is "Fruit"
If "$var" is "25"
To do the comparison, we use the "==" double equal sign.
then inside the curly brackets { }
You echo, if it is fruit, or you write a code here to do something in the program
then the else { }, to write somthing if it is not true.
true is 1, and false is 0
A lot of times you will use, this if ( ) { } else { } Statement
As always, write a lot of code everyday, and read, study and learn.
