2. Locate and extract the ZendGuardLoader.so (Linux) or ZendLoader.dll (Windows) that corresponds to your PHP version.
3. Add the following line to your 'php.ini' file for loading the ZendGuardLoader:
• Linux and Mac OS X:

zend_extension=<full_path_to_ZendGuardLoader.so>

• Windows non-thread safe (TS is not supported):

zend_extension=<full_path_to_ZendLoader.dll>

4. Add an additional line to your 'php.ini' for enabling ZendGuardLoader:

   ; Enables loading encoded scripts. The default value is On
   zend_loader.enable=1

5. Optional: the following lines can be added your 'php.ini' file for ZendGuardLoader configuration:

   ; Disable license checks (for performance reasons)

   zend_loader.disable_licensing=0

   ; The Obfuscation level supported by Zend Guard Loader. The levels are detailed in the official Zend Guard Documentation. 0 - no obfuscation is enabled

6. If you use the Zend debugger as well, please make sure to load it after the Zend Guard Loader.
