Hi, I get a prefix string from a database and store it in $var(prefix). Such prefix can contain any number of digits (no fixed length). Now I must to check if the RURI username begins with that prefix and in that case strip it.
I can get the first step (detect it) using pcre_match function:
if pcre_match("$rU", "^$var(prefix)") { # Prefix match.
But I cannot get the second part working (stripping it). I've tryed everything:
- strip() is not valid as just allows an integer (no pv).
- subst_user() doesn't accept pv: if subst_user("/^$var(prefix)(.*)$/\1/")
Any ideas please? Thanks a lot.
