[PHP] return all non-tag characters

[Matt Palermo]

I want to be able to retrieve and return all character that are not
located in html tags.  For example:
 
<font size=\"3\" color=\"#336699\">1234567</font>
or
<marquee>1234567</marquee>
 
I would just like it to be equal to 1234567, but I would need it to work
with any tags and attributes.  Is there a way to just throw out
everything from the < to the > and just keep everything that is NOT
located inside any <> characters?  Anyone have any ideas on how this can
be done?  Please let me know.
 
Thanks,
 
Matt
