Decode encrypted PHP Code

I have some PHP source code from a developer since years, and the developer stopped to be active (mail down and so on). Now one part of the Code is encrypted with some strange code, and i am unable to make a urgent needed change. So i need someone who make plain PHP code of this encrypted code. Part of the Code below, i will give the worker the full source! (Code see attach) For Copyright reasons! "I, Marcel Hennerbichler, affirm under penalty of perjury that I own copyright to the code which is being decrypted, and that, to the best of my knowledge, the deliverables being created for this project will not violate any US or International copyright laws. I further understand and release [login to view URL] and Exhedra Solutions, Inc., from any civil or criminal liability with regard to the completion of this project through the [login to view URL] site."
