My experience with POSIX regexes is also quite limited, but have you 
tried Google'ing for comparisons between PCRE (PHP's preg_* 
functions are built on top of PCRE) and POSIX regexes?

A quick search turned up: <http://www.regular-
expressions.info/refflavors.html>, which happens to be a helpful 
regex site I've used in the past.

With regard to this specific piece of code, I can't see any obvious 
differences in the way this regex pattern behaves in PCRE and POSIX. 
For differences in how each function behaves differently, simply 
consult the PHP documentation (which also contains a section 
explaining PCRE regex syntax).

For a more comprehensive understanding of the two flavors, I would 
settle for nothing less than reading the PCRE manual and the POSIX 
standard regarding its implementation of regexes.
