To verify whether Zend Optimizer is installed, execute:

root@server [~]# php -v

You can install the other available extensions using the same command, just replace ‘Zendopt’ with the extension name you wish to install.

To remove ‘Zend Optimizer’ from the server, just execute

root@server[~]# /scripts/phpextensionmgr uninstall Zendopt

Edit the php.ini file and comment the line that states

zend_extension=”/path/to/ZendOptimizer.so”

under the ‘[Zend]‘ section. In this case, make sure you restart the httpd service for the changes to take affect.
