PHP basics

You should always begin a PHP page with <?php and end with ?>
Your php code should go between <?php and end with ?> . You can for example code php , close , then add html code in between as below.
<?php Code ?>
We define a variable in PHP as follow, by the way a variable is anything we use as a shortcut to value.

 = "hello World";
The above example will print hellow World.

We call a variable by echoing or simply including it in php as follow :
echo ; or ;
Don't forget to ; at the end of a variable.

Html code here
<?php rest of php code and end with ?>

Always save a php page in a .php extention. For example, you save example as example.php, otherwise your php code will not work.
