This is known as heredoc. It's essentially a way of defining the value of a variable that spans multiple lines, and doesn't require escaping like traditional strings. The "CON" part is merely an identifier that represents the start and end of the value. This can be changed to a more familiar value.

+1 Solid answer. One thing to note may be that the last line
EOD; can not be indented afaik (making for some ugly code sometimes).

Correct, ChristopheD. Nothing before the last identifier, and nothing after (with the exception of the semi-colon).
That's the PHP heredoc operator. Details at this link:
