What do you call this "$out = <<OUT ... OUT;" ?

[cjohnweb]

So I am trying something new in a script and I can't seam to find more information on it.

I've seen it and I've used it, but what do you call it? How would you search for it?

<?php

$var = <<<UPPERCASELETTERS
"Some Content in which I don't have to escape Quotes or Apostrophes."
It's pretty cool!
UPPERCASELETTERS;

?>

I've tried searching for = <<< and the like but can't find anything. Anyone know where the info on this function is located on php.net? That's really what I am looking for, the php.net reference page = <<<OUT functionality.

Thanks!

It's called heredoc syntax
It has a brother called nowdoc (here and now - geddit?!)
