Zend Optimizer

What is Zend Optimizer?

Zend Optimizer is an awesome free app which allows and lets PHP to run files encoded by Zend Guard.

Zend Optimizer really enhances the performance of PHP applications.

The Zend Optimizer is a service that runs the files encoded by the Zend Encoder.


The standard Zend run-time compiler used by PHP code is actually very fast, which generates code that is normally 3 to 10 times faster than other PHP code.

However, an app that uses Zend Optimizer can execute scripts 40% to 100% faster.

After now somewhat outdated PHP 5.3, Zend Optimizer is included in the standard PHP distribution and there are no more installations needed for it to work.

Zend Guard Compatibility:

The encoded files must be compiled with a compatible version of Zend Guard.

When you arn’t sure about the Zend Guard version, always use the latest version of Zend Optimizer.

But if the versions of Zend Guard and Zend Optimizer are not compatible, the Optimizer will probably fail to run the encoded files and will display an error message.

To ensure that Zend Optimizer is properly running for you, create a phpinfo.php file and open it with your browser.

The part associated with Zend Optimizer would look like this code:

This program makes use of the Zend Scripting Language Engine:
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies

The Zend Optimizer is capable of performing about 21 different optimizations. Some of those are kind of complex.

One of the optimizations Zend Optimizer does is to change post-incrementing to pre-incrementing.

Where possible since pre-incrementing is the quicker operation of the two.

You can adjust your Zend Optimizer to perform only the best and desired optimizations. Each optimization can be turned on or off by setting the corresponding option.
