You should include in the PHP docs that the naming rules apply to namespaces, as at the moment their no mention of it. Out of interest, is there any reason why the naming rules doesn't allow the names to start with numbers? ------------------------------------------------------------------------ [2009-10-30 12:08:30] colder@php.net namespaces' names follow the same rule as classes/functions' names, which can't start by numbers either. ------------------------------------------------------------------------ [2009-10-30 10:49:38] me at gerryevans dot com I have tested this error on a CentOS server running Apache 2 + PHP 5.3 and Lighttpd + PHP 5.3. The php.ini both times was a php.ini-production with the only change "expose_php" to Off. ------------------------------------------------------------------------ [2009-10-30 10:35:03] me at gerryevans dot com Description: ------------ PHP doesn't like it when a namespace starts with a number for example a namespace 12eggs will get a parse error ("syntax error, unexpected T_LNUMBER, expecting T_STRING or T_NS_SEPARATOR or '{'").
