createFilename returns empty string

Works fine locally but moving to a client server it stops working. The problem is in:

preg_match_all('/[p{L}w:;.,+=~]+/', $string, $matches);

Changing it to:

preg_match_all('/[w:;.,+=~]+/', $string, $matches);

Solves the problem.

What was p{L} doing anyway? I thought the {...} syntax is for doing X number of items… but the L?

@Nick: It’s to do with unicode matching. here’s some info http://www.regular-expressions.info/unicode.html. Problem is, PHP’s regex functions don’t really support unicode matching.

This issue is closed.
