This HTML is treated like it's EXPLICITLY printed, but the only thing special about it...

It's HTML "in the way" of a server loop (no PHP here!)

Because the server had to read it 3x, it is in fact sent by the server 3x.

=1; $i--) { $h=$h ."

[Data {$i}]

" ; } ?> This HTML is prepared ahead of time with a replacement variable & dumped all-at-once like:

cpp: printf("%d", 1)

or

Python: "%i".format(1)

It's still all sent by the server though.

What if I want to print a LOT of similar things...or maybe just 3 things to 10,000 clients? Should I do all the prints (echoes) in PHP? NO!!! A server has more important stuff to do than babysit clients (and do you know how LONG that would take?). Send grunt work to the CLIENT. alert('Client message: Writing ok! to the document {$this_many_times} times with injected javascript.'); document.write('

Client output:
'); for(var i=1; i<={$this_many_times}; i++) { document.write(''); // or a function on the client, or a var of server data if(i%10==0) document.write(''); } document.write('

ok!

Your PC/mobile did this work, not the server.'); " ?>
