You only need { ... } when expanding multi-dimensional arrays or
objects. Once inside { ... } you must follow the proper quote syntax for
key names.
You can assign a HEREDOC to a variable just like anything else and
variable expansion works there too:
$str = <<<EOF
blah blah $color_red blah blah
{temp[0][1][2]}
blah blah
EOF;
