     escape them first. If you think <B

     any other regex function, for that matter) is doing something
     weird, please read the file <TT

     included in the <TT
CLASS="filename"
>regex/</TT

     PHP distribution. It's in manpage format, so you'll want to do
     something along the lines of <B
CLASS="command"
>man
     /usr/local/src/regex/regex.7</B
