It is the start of a "heredoc"
http://www.php.net/manual/en/language.types.string.php#language.types.strin g.syntax.heredoc

Specifically, the word immediately adjacent to the right of the <<< (in your
case, the word BLAH) is taken as a sentinal, and all lines between the line
containing the start of the heredoc (the <<<BLAH line) and the first line
that contains the sentinal word are treated like a single string.

Thus
<<<BLAH
this is a test
one two three
four five
six
BLAH;

is treated as a single string consisting of
"this is a test\none two three\nfourfive\nsix\n"
