I can't seem to figure out why any changes I make to php.ini and restart apache (apachectl stop|start; grep of any httpd processes), the settings do not update. php -r "phpinfo();" | grep Configuration Configuration File (php.ini) Path => /etc/php.ini Configuration I installed extensions via yum and they don't show up. # rpm -qa|grep php php-gd-5.1.6-27.el5 php-mysql-5.1.6-27.el5 php-pear-1.4.9-6.el5 php-common-5.1.6-27.el5 php-cli-5.1.6-27.el5 php-devel-5.1.6-27.el5 php-pdo-5.1.6-27.el5 php-5.1.6-27.el5 Can I load extensions via httpd.conf like how you override defaults?
