Possible, he might be a very bright and promising kid. Average: certainly not. I regard this as statistical outlier. I'd offer 50-60k max for a 2 years php dev. We do have a large influx of people from Spain and Greece lately - they're legally allowed to work here without any visa and the unemployment rate drives them here.

However, if those numbers are cited it's difficult to know which side you're hearing. An employer in germany has to pay health care and social security etc., which adds another ~40% on top of the wage - so they might have cited that number to compensate for differences in the american model (private healthcare paid by the employee).
