No, because it is inside the apostrophes.

The purpose of mysql_real_escape_string (or using prepared statements)
is to mark up (or separate) the DATA from the QUERY.

The data about to be put into the database being escaped by
mysql_real_escape_string is sufficient to be sure nobody is playing
games with apostrophe followed by -- which could, in theory, insert an
SQL comment or allow them to execute arbitrary SQL code.
