#33123 [NEW]: mysql_field_len() not working with utf-8

From: rober_box at mailforce dot net Operating system: Gentoo Linux 2005.0 PHP version: 4.3.11 PHP Bug Type: MySQL related Bug description: mysql_field_len() not working with utf-8 Description: ------------ mysql_field_len() doesn't return the correct field len for utf-8 fields. Instead it returns the maximum length mysql allows (i.e 3 bytes). That way i can't check user input for length sanity. My configuration: './configure' '--prefix=/usr' '--host=i686-pc-linux-gnu' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--datadir=/usr/share' '--sysconfdir=/etc' '--localstatedir=/var/lib' '--with-apxs2=/usr/sbin/apxs2' '--without-db3' '--without-db4' '--without-db2' '--without-ndbm' '--with-mcrypt=/usr' '--with-mhash=/usr' '--without-interbase' '--without-ming' '--without-swf' '--without-sybase' '--with-gdbm=/usr' '--without-fdftk' '--without-java' '--without-mcal' '--without-unixODBC' '--without-pgsql' '--without-snmp' '--with-xpm-dir=/usr/X11R6' '--without-gmp' '--without-mssql' '--with-pdflib=/usr' '--with-gd' '--enable-gd-native-ttf' '--with-png=/usr' '--with-png-dir=/usr' '--with-jpeg=/usr' '--with-jpeg-dir=/usr' '--enable-exif' '--with-tiff=/usr' '--with-tiff-dir=/usr' '--with-mysql=/usr' '--with-mysql-sock=/var/run/mysqld/mysqld.sock' '--with-freetype-dir=/usr' '--with-ttf=/usr' '--with-t1lib=/usr' '--with-gettext' '--with-qtdom=/usr/qt/3' '--with-pspell=/usr' '--with-openssl=/usr' '--without-imap' '--without-ldap' '--with-dom=/usr' '--with-dom-xslt=/usr' '--with-dom-exslt=/usr' '--without-kerberos' '--with-pam' '--disable-memory-limit' '--enable-ipv6' '--without-yaz' '--disable-debug' '--with-curlwrappers' '--with-curl=/usr' '--enable-dbx' '--with-zlib=/usr' '--with-zlib-dir=/usr' '--with-sablot=/usr' '--enable-xslt' '--with-xslt-sablot' '--with-xmlrpc' '--enable-wddx' '--with-xml' '--enable-mbstring=all' '--enable-mbregex' '--with-bz2=/usr' '--with-crack=/usr' '--with-cdb' '--enable-pcntl' '--enable-bcmath' '--enable-calendar' '--enable-dbase' '--enable-filepro' '--enable-ftp' '--with-mime-magic=/usr/share/misc/file/magic.mime' '--enable-sockets' '--enable-sysvsem' '--enable-sysvshm' '--enable-sysvmsg' '--with-iconv' '--enable-shmop' '--enable-dio' '--enable-yp' '--without-ncurses' '--without-readline' '--enable-inline-optimization' '--enable-track-vars' '--enable-trans-sid' '--enable-versioning' '--with-config-file-path=/etc/php/apache2-php4' '--without-pear' '--libdir=/usr/lib/php' '--with-pear=/usr/lib/php' Reproduce code: --------------- $fields = mysql_list_fields($link, $table) or msg_error(mysql_error()); $len = mysql_field_len($fields, $i); echo $len; Expected result: ---------------- I expect to see the actual length as shown by issuing a SHOW FIELDS FROM table query. For example if a field is VARHCHAR(8) i expect to see 8, not 24.
