Hi,
It sounds like you need to paramterize your REST resource using a SoapUI Property Expansion http://www.soapui.org/scripting---properties/property-expansion.html
e.g. with something like /pho-rest/lan/${id} where the value of the property expansion (placeholder) ${} can be provided from something like a Groovy expression, data file etc
Here is a previous discussion / solution that you may hopefully find helpful http://community.smartbear.com/t5/SoapUI-Open-Source/Parametrizing-Endpoint-Resource-Method-and-paramter-values-in/m-p/102919#M18026
If not, there are many other threads, videos & blogs, that we can look for and discuss on the topic of Data Driven testing in SoapUI - its a very popular topic with plenty of (Groovy Script) options in SoapUI! :-)
Let me know if you need more pointers,
Cheers,
Rupert
