Most of the times we forgot to add some php modules/extensions and which we required to fulfill the requirement of the website, so you can install the particular missing modules with the help of below steps instead of performing the complete Easy apache on the cpanel server :
cd /home/cpeasyapache/src/php-5.2.9/ext/XXXXX — >>> extension which you want to install
6. make install
7. After that you can see extension dir path. ll extension dir path.
8. vi /usr/local/lib/php.ini
10. Then restart apache
