string - Does echo in PHP starts printing on a new line? If no then why it's happening in my case? -

-

i've following php code:

<!doctype html> <html> <body>  <?php echo "<h2>php fun!</h2>"; echo "hello world!<br>"; ?>   </body> </html>

i'm not understanding why without adding <br> @ end of first echo statement next echo statement printing data on new line?

the same not happening in below example :

<!doctype html> <html> <body>  <?php echo "jumbo"; echo "hello world!<br>"; ?>   </body> </html>

i'm getting output jumbohello world!

why so? mean @ 1 place echo takes new line charcter before start printing text , @ place it's not.

please clear concept me in detail manner.

thanks.

when "new line" referring visually when viewing page in browser. in html have block-level elements, default appear on own line, , there line breaks, defined <br>

echo not add other tell output.

<h2> block-level element default, in first example, hello world! appear below it.

in second example, outputting <br> tag after text, meaning line break after hello world
