Help Please. Python Programmer to PHP? Is it possible?

I just moved to a new country and looking for a job. I am a Python programmer, more than 5 years experience in various web programming. I also quite good in Javascript, C, SQL, CSS, HTML, etc. The problem is that most jobs here require PHP. I know that I can transfer my experience to PHP given 1-2 weeks, but employers does not seem to believe me. Can you give me suggestions on how to convince them? If you believe they are right, kindly share me your thoughts. Please help me figure this out.
