if you want to sort the extensions from a to z the easiest way is to use natcasesort.

I was not sure of the Zend extensions. and no zend extensions was coming on my installation. print_r(get_loaded_extensions(true)); print zend extensions loaded. To know the zend extensions loaded in you installation, use phpinfo() and check where it says "This program makes use of ...". It is the third section in output. If you have Xdebug installed and enabled then this is a zend extension and it will be listed there.
