Zend Optimizer Settings
As mentioned earlier the Zend Optimizer goes over the intermediate code generated by the standard Zend run-time compiler and optimizes it for faster execution.
In order to customize the Optimizers performance, the following directives and extensions have been provided.
Directive |
Description |
zend_optimizer.enable_loader |
If you do not plan to use the Zend Optimizer |
|
to load encoded files, you can slightly |
|
improve the Optimizer’s performance by |
|
adding the zend_optimizer.enable_loader = |
|
0. This disables the transparent auto- |
|
loading mechanism that is built into the Zend |
|
Optimizer. |
zend_optimizer.disable_licensing |
If you do not need to use any licensing |
|
features, you can disable the Zend Optimizer |
|
license request. Setting this option lowers |
|
Optimizer memory usage and slightly |
|
enhances performance |
zend_optimizer.licence_path |
A license file is required to load encoded |
|
PHP scripts that were encoded with a |
|
“license” option. |
|
If you turn off this option, the encoded scripts |
|
on your server that require a license may not |
|
load. |
|
This directive is a list of directories or files, |
|
separated by path separator (; on windows,: |
|
on Unix) that gives the Optimizer a place to |
|
look for encoded file licenses. |
|
When directories are added to this path, all |
|
files ending in .zl will be loaded as licenses. |
|
If the file that was added to this path, was |
|
loaded as a license. |
|
Licenses are loaded on server start time |
|
(unless loaded by PHP API), so if you add a |
|
license or change a path, you should restart |
|
the server. |
zend_optimizer.obfuscation_level_support |
The Obfuscation level supported by |
|
Optimizer. |
Located in the zend.ini, these directives can be easily configured through Zend Platform and Zend Core (all flavors).
Note:
If you are using the Zend Optimizer along with Zend Guard to encode files, please refer to the Zend Guard User Guide for more information.

bool zend_loader_install_license(string license_file[, bool override])

int current_obfuscation_level() |
Note:
Description
Shown if loader is enabled.
Returns true if the current file is a Zendencoded file.
Returns license (array with fields) if the current file has a valid license and is encoded, otherwise it returns false.
Returns the name of the file currently being executed.
Dynamically loads a license for applications encoded with ZendGuard. The Override controls if it will override old licenses for the same product.
Obfuscate and return the given function name with the internal obfuscation function.
Returns the current run-time obfuscation level.
To“ insure” backward compatability with scripts obfuscated with the Zend Guard at level Basic , their run-time obfuscation level will remain 0 !
|
|
zend_runtime_obfuscate |
bool zend_runtime_obfuscate() |
zend_get_id |
array zend_get_id([bool all_ids = |
|
false]) |
10
Start runtimeobfuscation support that allows limited mixing of obfuscated and un-obfuscated code.
Returns array of the host ids. If all_ids is true, then all IDs are returned, otherwise only IDs considered "primary" are returned.

Zend Optimizer Technical FAQ
What is the Zend Optimizer? What does it do?
The Zend Optimizer goes over the intermediate code generated by the standard Zend run-time compiler and optimizes it for faster execution. In addition, the Zend Optimizer enables PHP to load and execute files encoded by the ZendGuardTM.
How do I get the Zend Optimizer?
The Zend Optimizer is available for download free of charge from the Zend Store, at http://www.zend.com/store/.
I have installed the Zend Optimizer. How do I start it?
The Zend Optimizer is a passive module that runs within the framework of PHP. It optimizes scripts automatically, and transparently detects and loads encoded files, therefore there is no need for you to start it.
How many optimizations does the Zend Optimizer perform altogether?
The Zend Optimizer is capable of performing around 20 different optimizations, some of which are quite complex. One of the simpler optimizations that the Zend Optimizer does is to change post-incrementing to pre-incrementing, where possible, since pre-incrementing is the faster operation of the two.
Is there any way to further improve the performance of the Optimizer?
If you don¶t plan to use the Zend Optimizer in order to load encoded files, you can slightly improve the performance of the Optimizer by adding the
directive to . This disables the transparentze d optimizerauto-loading.enablemechanismloader that= 0 is built into thephpZend.i i Optimizer.
Can encoded and non-encoded (source) PHP files be used together?
Encoded and non-encoded PHP files can be used together transparently.
Will using encoded files (instead of source files) change run-time speed or file size?
There might be some speed gain because the compilation stage is saved on every run of the script, however, speed improvements, if any, are dependent on the nature of the script. The size of an encoded file might be somewhat smaller or larger than the source file, but this too is dependent on the nature of the script. The factors that tend to improve run-time speed are not necessarily the same as those that tend to decrease file size.
When I start my server, the Zend Optimizer gives error messages and fails: Why?
Your version of PHP may be incompatible with the Zend Optimizer that you installed. Make sure that you download a version of the Zend Optimizer that is compatible with your version of PHP.
When I try to run an encoded file, error messages are displayed: Why?
The most common cause of error messages and failure is incompatibility either with the PHP version, or with the Zend Intermediate Code file (that is, with the version of the Zend Guard that encoded the file).
Another possible cause for failure could be encoded file corruption caused by transferring the file between systems. This happens because even though encoded
