ZendGuardLoader (Debian6)

直接下載 PHP 5.3 的 GuardLoader

解壓後應該獲得 ZendGuardLoader.so

把它 copy 到 /usr/lib/php5/20090626+lfs

在 /etc/php5/conf.d 加以下檔案

ZendGuardLoader.ini

zend_extension=<full_path_to_ZendGuardLoader.so>
zend_loader.enable=1
zend_loader.disable_licensing=1
zend_loader.obfuscation_level_support=3

最後 apache2ctl graceful 即可
