echo question?

[ballhogjoni]

if your compiler is running thru a php script and it reaches an echo does it print the echo out right then or does it wait till then end of the script to print it out?

 

EX:

<?php

//some php code

echo 'this stuff'; //does the compiler echo this right now or does it finish running through the entire script?

//some more php code

?>

PHP is interpreted not compiled unless you're using something like Zend but ultimately it is still interpreted.  Compilers do not run through scripts, this doesn't really make any sense to me.

 

What exactly is this script?

nothing just trying to understand when php sends the echo to the browser.

If in CMD line, PHP will output each echo.

If in a webserver, the content will not be sent to the browser until the script is done.

php will always do it's processing on the server and send the html over in one chunks... if you've ever tried to do:

 

header('location: somewhere.php')

 

after echoing or outputting any html or blank spaces you'll see this in action...

I'm guessing that your question is related to this thread - http://www.phpfreaks.com/forums/index.php/topic,232730.0.html

 

php, web servers, and browsers all do various buffering/compression that prevent incremental content from being sent to the browser.

 

Web servers are designed to receive requests for (whole) web pages and output those whole pages. If you want to do anything on a smaller scale, you must generate a separate request for each piece of information (i.e. AJAX.)
