The reason that a single \ in front didn't work is that \ is ALSO special character for ' in PHP, and it just escapes the - so that you have NOT sent \- to EREG, but sent it the same thing you were sending it before you added \ You would need \\ inside of '' (or "") in PHP to get a single \ sent to EREG which would then be used by EREG to escape the - '...\\- ,/' PHP takes \\- to produce \- which EREG takes to produce [character -] instead of [range operator -] You should probably review the "strings" page at the beginning of the PHP manual. -- Some people have a "gift" link here.
