What is the use of <<<EOD in PHP?

I know how to use it, I know it’s used to mark Heredoc’s syntax to easily print multiple lines of string, but what is full name of that EOD acronym (if it’s acronym) ?
Only thing I heard is End Of Data, but I’m not sure if it’s good.

Answer 1

EOD isn’t part of the Heredoc syntax. It’s just used in their example.

$foo = <<<JAVASCRIPT
  alert('Hello!');
  alert('World!');
JAVASCRIPT;

This example would echo the javascript back to the user (or in other words, until the Token JAVASCRIPT is reached).
