PHP5: utf8_decode() undefined

Hi, my setup-info is at http://217.116.80.30/info.php The following script gives PHP Fatal error: Call to undefined function utf8_decode() in /home/fontana10/web/utf.php on line 4 Why? I have enabled XML support and am running the newest port (on FreeBSD)of all the libraries needed: <? error_reporting(E_ALL); utf8_decode(); ?> Anyone? These are my configure arguments: './configure' '--enable-versioning' '--enable-memory-limit' '--with-layout=GNU' '--with-config-file-scan-dir=/usr/local/etc/php' '--disable-all' '--enable-libxml' '--with-libxml-dir=/usr/local' '--enable-spl' '--with-regex=php' '--disable-cli' '--with-apxs2=/usr/local/sbin/apxs' '--disable-ipv6' '--prefix=/usr/local' '--with-bcmath' '--with-bzip2' '--with-calendar' '--with-cdb' '--with-crack' '--with-ctype' '--with-curl' '--with-dio' '--with-domxml' '--with-domxslt' '--with-exif' '--with-filepro' '--with-fribidi' '--with-ftp' '--with-gd' '--with-gettext' '--with-iconv' '--with-imap' '--with-inifile' '--with-mbstring' '--with-mcal' '--with-mcve' '--with-mcrypt' '--with-mhash' '--with-mime' '--with-ming' '--with-mngosearch' '--with-mysql' '--with-openldap' '--with-openssl' '--with-overload' '--with-pcntl' '--with-pcre=/usr/local' '--with-pdflib' '--with-posix' '--with-postgresql' '--with-swssion' '--with-shmop' '--with-sockets' '--with-sysvsem' '--with-sysvshm' '--with-tokenizer' '--with-wddx' '--with-xml' '--with-xmlrpc' '--with-xslt' '--with-yp' '--with-zip' '--with-zlib' '--with-batch' '--with-apxs2' '--with-xslt-sablot' '--with-pspell' '--with-snmp' '--with-readline' '--with-gmp' '--with-pcre-regex' '--with-expat-dir=/usr/local Cheers Nik
