Hello, World

What World is This?

I see. OK. we will be leaving now.

Now ... 1. if you want to serve juice with fries, ok.
That was the standard <?php echo --; ?> syntax.

2. some editors are more confusing than the language they generate.
This was the <script language="php"> --; </script> syntax.

3.   This is a test
This is a test
We restored the last closing tag

If that did what I expect, there are 3 visible statements above. No semicolon in 2nd.
Semicolon is not essential, but closing tag is. ?

4.   Now is time for a bigger test.

.

A complete flop. Techie php files are inscrutable.

===========================================

Switching to the David G. tutorial where presentation is ... different.
Below, I use <? without php, encloses print(" "); as command instead of echo ' ';

1. Hello world! -hph

2. Here I define a string variable called "welcome_text." -hph var def, no display.

3. Now I hope to display it using echo instead of print. Hello and welcome to my website. -hph

4. I change the font in html, & try David's print command again.
Hello and welcome to my website. -hph

If all errors, it'll be back to web matrix to highlight them. Php didn't work in Xampp last I tried it.
