I need to add the mbstring extension to an install of PHP 5.2.6 on Apache/2.2.11 (Fedora). We have dynamic extensions enabled so I really think all I need is the .so file and .ini files, correct? Can I simply drop these files in and make it work or do I have to recompile PHP? If it’s simply upload and go, where can I get the files I need?
yum install php-mbstring. You may then need to restart apache, e.g.
/sbin/service httpd restart.
You can also use
yum info "php-*" to find a list of other php packages available.
