I'm pretty new to using PHP and MySql on linux (Red Hat 9) so hopefully somebody can help me. When I created a php file with mysql_connect() function I got "call to undefined function". I done some research and checked the php.ini file - I triedd adding extension=mysql.so but it didn't work. Then I saw a note in the php.ini file saying for Red Hat this should be done through confiugration files in the /etc/php.d directory. So I created a file called mysql.ini and added in the same line as above but this still didn't work. Now I've just checked the /usr/lib/php4 directory and there's no mysql.so file there. Why is this and what do I have to do to get it?
