Regular expression problem

[hkucsis]

Hi,

I want to change some file names from lower case to upper case, I use eregi() (for some reason, strtoupper() is not appropriate).

ereg_replace("(/[a-zA-Z0-9-]+.(doc|wpf))", $replace, $content);

My question is, how to access the string that match the regular expression? \0 ? So that I can set $replace to strtoupper(\0).

Thanks,
Michael

Have a look at preg_replace() instead - particularly the use of the /e modifier.

But I have to say, what you're describing is identical to strtoupper anyway - I think you're mistaken about which backreference you want and where your parenthesised subexpressions should end.
