Recently I had configured Web server with PHP under Fedora core. Everything was working fine except the installation of phpMyAdmin, reported an error as follows:
The mbstring PHP extension was not found and you seem to be using a multibyte charset. Without the mbstring extension phpMyAdmin is unable to split strings correctly and it may result in unexpected results.
Following command helped me to find out the exact package name:
# yum search mbstring
Following command installed the package php-mbstring.i386 for fedora core 4:
# yum install php-mbstring.i386
Do not forget to restart web server.
