Symisc PH7 Engine
An Embeddable PHP5 Engine

PH7 Engine Licensing Information.

The PH7 engine is an open source product. That is, the complete source code of the engine, the official documentation and related utility are available to download from the Symisc download page.


Symisc Systems (Developer of the PH7 engine) employs a dual licensing model that offers customers a choice of either our open source license or a commercial license. Our open source license is the Symisc Public License (SPL). The SPL is a three-clause license, GPL compatible and is equivalent to the more popular Sleepycat license (An OSI approved license) and permits use of PH7 in open source projects or in applications that are not distributed to third parties. The commercial license permits closed-source distribution of an application to third parties.


The Symisc Public License permits you to use the PH7 engine at no charge under the condition that if you use the engine in a host application, the complete source code for your application must be available and freely redistributable under reasonable conditions.


If you do not want to release the source code for your application, you may purchase a license from Symisc Systems.


If you want to acquire a license and/or for pricing information, please send an email to:

licensing@symisc.net.


If you have further questions on licensing and/or for legal issues, please send an email to:

licensing questions

    1) What does "redistribute" mean?

"redistribution" in the open source world means your application is distributed to one or more third parties. Giving an application to customers, even in alpha or beta releases, is redistribution. Giving contractors, affiliates, parent organizations or subsidiaries, business partners or support vendors a copy of the application is generally redistribution.

Whether or not you charge money for your application does not matter. The only condition is redistribution.

Building/Releasing an application for internal use is not considered redistribution.

Again, if you have any questions on licensing and/or for legal issues,please send an email to:

legal@symisc.net.

2) What must I release as open source?

Under the open source license, you must release the complete source code for the application that embed the PH7 engine. You do not need to release the source code for components that are generally installed on the operating system on which your application runs.

3) What open source license should I use in my project?

Any project that uses a license recognized by the opensource.org (OSI board) such as the GPL, BSD, MPL and so on can incorporate the PH7 engine without any legal constraint. Of course, releasing an application which embed the PH7 engine under an open source license does not change the requirements of our open source license, and the PH7 source code remains subject to the terms of the Symisc Public License.


Public domain application where their source code is freely available to the public can embed the PH7 engine free of charge without any legal constraint.


If your project uses a license not listed in the opensource.org site and you think that is compatible with our open source license, again send an email to legal@symisc.net with a copy of the license in question.
