Why am i getting html code also after execution of my php file in tutorialspoint ?

Question

syntax overview in tutorialspoint​

Answer 1

If I have a letter:

Dear {salutation} {last_name}:
We are writing to.....

The "HTML" is:

Dear :
We are writing to....

and the rest, which you could call replacement placeholders, is pre-processed 'in addition' to the underlying HTML, so that when you are done the resulting first line might be:

Dear Mr. Jones:

That's the 'templating' concept (php, angularJS, etc). So specifically for php:

Dear <?php echo($salutation); ?> ....

But PHP (a "hypertext processor") is also a full language, which runs on the server...so you can do a whole lot more on that side: spit out custom HTML, whole pages, tiny data responses to javascript queries, etc.

Answer 2
