The first php program

The first php program

 &#&&#&&#&echo&#&"Hello&#&PHP";
?>
Running this program will be displayed in the browser String "Hello&PHP"
A little explanation:
(1) PHP file structure

&#&Write php code here&#&
? >
(2) echo& is an output function. The end mark of each PHP statement is a ";" semicolon, just like most languages.
(3) Simple comment of php&
&
&&//& is a simple single line comment
/**&*/& When commenting on a paragraph, please do not nest comments, otherwise errors will occur.
The above introduces the first PHP program, including various aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
