CodeIgniter PHP alternative syntax

Experts:

I'm new to CodeIgniter.  I see code like <?=$Hello_World?> replaces the echo function in a project I'm working on.  My question is,  is this syntax an extension of PHP that I can find on php.net or it's specific to CodeIgniter?  Who translates it to native PHP code before PHP process the source file?

That is a shorthand form for <?php echo $Hello_World ?> and works the same.

It is part of PHP but I believe that it requires the setting in php.ini

short_open_tag = On

This is not part of the answer, but my opinion, and you know what they say about opinions....

At any rate, I believe that you should avoid using short tags. They are not recommended and a php script that is written with short tags will not run on a server where they are disabled. What happens if this happens is that all of you code is output and visible to all. Not all hosts will turn short tags on.

Also, starting in PHP 6 short tags will be eliminated, or that is what I've read. So, everyone needs to get out of the habit of using short tags anyway.

Your best bet is to continue to use what you have always used <?php echo... rather than <?=...
