PHP <<< (multi-line handler?) question

I have some code as follows:

$query = <<<QUERY
SELECT
    *
FROM
    names
WHERE
    create_date > date('Y-m-d H:i:s');
QUERY

How can I put the date(开发者_如何学Python'Y-m-d H:i:s') in there without breaking out of the <<< statement?

You could store that piece of code in a variable and use substitution.

$now = date('Y-m-d H:i:s');
$query = <<<QUERY
SELECT
    *
FROM
    names
WHERE
    create_date > $now;
QUERY;

$date = date('Y-m-d H:i:s');
$query = <<<QUERY
SELECT
    *
FROM
    names
WHERE
    create_date > $date
QUERY
