It was changed in 5.1.0-5.1.1 versions. According to PHP Manual (http://www.php.net/language.types.string) curly brackets are not escaped with backslash. Escape worked in older PHP versions. It does not work in 5.1.1+. http://bugs.php.net/31341 http://bugs.php.net/35411 -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
