Re: How can I solve this?

A friend of mine updated your regular expression... Check it out if your interested. Jeremy

Dear Jeremy, Thanks for writing! I saw this regular expression and thought you might like it... :)

preg_replace("/^\/?(.*)\/[\w]+\.php$/","$1",$PHP_SELF) that strips that leading forward slash too ;-)

\w is a PCRE (Perl-Compatible Regular Expression) that matches any word character: a-z, A-Z, 0-9 and the underscore "_". sed and awk do not support \w, although ssed (super-sed) supports \w if an -R switch is added on the command line. Back to PHP and \w : Putting \w by itself inside a character class "[...]" does absolutely nothing, just as "[a]" and "[9]" does nothing special. It could be more efficiently written as:

        /^\/?(.*)\/\w+\.php$/

One additional problem is that the characters defined by \w does not include the hyphen, the pound sign, or other punctuation marks that sometimes find their way into filenames, like:

        four-to-go.php
        page#10.php
        convert$toDM.php

so in this case, a character set should be used:

        /^\/?(.*)\/[\w~!@#$%^&*+=-]+\.php$/
