Question

I have seen the <<< operator many times , but I can’t find any mention of this operator in PHP documentation. Can anyone please tell what this operator exactly does?

Answer 1

Full explanation here.

With a bit easier explanation here.

Heredoc syntax is a way to delimit
strings in PHP (and other languages)
with 3 “less than” symbols: <<<.

The good part about it:

Heredoc text behaves just like a
double-quoted string, without the
double quotes. This means that quotes
in a heredoc do not need to be
escaped. Variables are expanded, but
the same care must be taken when
expressing complex variables inside a
heredoc as with strings.
