Zend Guard Loader - PHP API

This topic lists the PHP API functions of the Zend Guard Loader.

Zend Guard Loader Functions

Function	Description
zend_loader_enabled	Checks the Zend Optimizer+ configuration to verify that it is configured to load encoded files
zend_loader_file_encoded	Returns TRUE if the current file was encoded with Zend Guard or FALSE otherwise. If FALSE, consider disabling the Guard Loader
zend_loader_file_licensed	Compares the signature of the running file against the signatures of the license files that are loaded into the License Registry by the php.ini file. If a valid license file exists, the values of the license file are read into an array. If a valid license does not exist or is not specified in the php.ini, it is not entered in the PHP server's license registry. If a valid license that matches the product and signature cannot be found in the license directory, an array is not created. For information on the proper installation of a license file, as well as the php.ini directive, see the Zend Guard User Guide
zend_loader_current_file	Obtains the full path to the file that is currently running. In other words, the path of the file calling this API function is evaluated only at run time and not during encoding
zend_loader_install_license	Dynamically loads a license for applications encoded with Zend Guard.
zend_obfuscate_function_name	Obfuscate and return the given function name with the internal obfuscation function
zend_current_obfuscation_level	Returns the current obfuscation level support (set by zend_optimizer.obfuscation_level_support) to get information on the product that is currently running.
zend_runtime_obfuscate	Start runtime-obfuscation support to allow limited mixing of obfuscated and un-obfuscated code
zend_obfuscate_class_name	Obfuscate and return the given class name with the internal obfuscation function
zend_get_id	Returns an array of Zend (host) IDs in your system. If all_ids is TRUE, then all IDs are returned, otherwise only IDs considered "primary" are returned
zend_loader_version	Returns Zend Guard Loader version
