encode_php
Encodes any special characters so that the string can be used safely as the value in PHP code.
The value of the attribute can be either qq (double-quote interpolation),
here (heredoc interpolation),
or q (single-quote interpolation).
q is the default.
Example:
    <?php
    $the_title = '<$MTEntryTitle encode_php="q"$>';
    $the_author = "<$MTEntryAuthorDisplayName encode_php="qq"$>";
    $the_text = <<<EOT
    <$MTEntryText encode_php="here"$>
    EOT
    ?>
