331 * Older version (pre 3.x?) of the PCRE library do not support
332 * POSIX named character classes (e.g. [[:alnum:]]).
334 * This is a helper function which can be used to convert a regexp
335 * which contains POSIX named character classes to one that doesn't.
337 * All instances of strings like '[:<class>:]' are replaced by the equivalent
338 * enumerated character class.
340 * Implementation Notes:
342 * Currently we use hard-coded values which are valid only for
343 * ISO-8859-1. Also, currently on the classes [:alpha:], [:alnum:],
344 * [:upper:] and [:lower:] are implemented. (The missing classes:
345 * [:blank:], [:cntrl:], [:digit:], [:graph:], [:print:], [:punct:],
346 * [:space:], and [:xdigit:] could easily be added if needed.)
348 * This is a hack. I tried to generate these classes automatically
349 * using ereg(), but discovered that in my PHP, at least, ereg() is
350 * slightly broken w.r.t. POSIX character classes. (It includes
351 * "\xaa" and "\xba" in [:alpha:].)
353 * So for now, this will do. --Jeff <dairiki@dairiki.org> 14 Mar, 2001
