That's a short way of assigning a variable a value that spans multiple lines and includes special characters that would normally interfere with the PHP language.

It's called NOWDOC (see http://www.php.net/manual/en/languag....syntax.nowdoc)

Consider this example:

Help with Code Tags

php Syntax (Toggle Plain Text)

$text = <<<SPECIAL_LABEL
The quick brown
fox jumps over
the lazy dog.
SPECIAL_LABEL

This assigns the sentence (including line breaks) to the variable $text.

The syntax is:

$variable = <<<LABEL
contents go here....
LABEL

So, in your example, the value stored in $post is:

<form method="post" action="">
</form>
