In a new post to he blog Zoe Slattery helps developers to answer the question "will my application run on Project Zero?" (IBM's development/execution platform) She's come across a tool that can help with just that.
There is a new Project Zero application which will scan your application and tell you whether it thinks it will run on Project Zero. The way it does this is to extract information from the Project Zero PHP parser - for instance it finds out the names of functions that are declared in the application and compares them with the names of functions that are invoked.
The scanner looks through the code and, when it finds a function that's not user-declared, checks it against the Project Zero PHP functionality to make sure it will work.
