a little PHP reg exp help pls

["Chad A. Adlawan" <ch4di@yahoo.com>]

hi!

i would like to search out all non-numeric characters in my string and replace
them with nothing in PHP.
i tried

preg_replace("[^0-9]","",$my_string);

but, i get this error: Warning: No ending delimiter found in
/var/www/html/mm/tmp2.php3 on line x

can somebody help me do this correctly pls?

thanks a lot in advance,
chad


INXS: "perl -pi -e 's|[^0-9]||g' file.here" works perfectly in command line
perl.  so what did i do wrong when i tried it in PHP?
