What is Zend Optimizer? What does Zend Optimizer do?

The Zend Optimizer provides a platform enabling PHP to load and execute files encoded by the ZendGuard. It goes over the intermediate code generated by the standard Zend run-time compiler and optimizes it for faster and efficient execution.

How can I get the Zend Optimizer?

The Zend Optimizer is available with our Web Hosting Packages. The versions vary according to the Web Hosting package.

How many optimizations can the Zend Optimizer perform altogether?

The Zend Optimizer holds the capability to perform 20 unique optimizations. Some of them are very complex, one simple optimization is that the Zend Optimizer can change the post-incrementing to pre-incrementing, wherever it is possible. Pre-incrementing is a faster operation.

Will there be any change in the run-time speed by using encoded files instead of source files?

Speed improvements are based on the nature and complexity of the script, however there can be some speed gain because the compilation stage is spared on every run of the script.

When I start my server, the Zend Optimizer gives error messages and fails?

The version of PHP being used by you might not be compatible with the Zend Optimizer installed. It is recommended to install the version of Zend Optimizer that is compatible with the PHP version being used by you.

Error messages are displayed when I try to run an encoded file?

This could be because of compatibility issues with your PHP version and the Zend Optimizer version. Another reason could be that the encoded file corruption caused by transferring the file between systems. To avoid this, it is recommended that you use “binary transfer mode” when transferring encoded files with file transfer tools.
