[PATCH] Better regular expressions in the PHP Parser

[Sebastian Gutweiler]

Hi,

when using the PHP-Part I had the problem, that the Parser, when parsing
a class called "mp3", only added "mp" to the class store. When looking
at the source code, it tourned out, that the Parser also ignored files when
they contained a special char, like the German umlauts, but they are
allowed in PHP. 
This patch fixes this and makes the checking stricter. If, for
example, a variable begins with a figure, it is ignored and not added to
the class store, because this is not allowd in PHP. 

Sebastian
