When writing a backend for android, why is php preferred over java?

Question

PHP

In advantage of php over java in this case?

Answer 1

In most cases, as I think, because backing written in php is cheaper to maintain (at least if the project is small).

Answer 2

PHP programmers are cheaper and easier to find. This is the only reason. Why? Because the entry threshold in php is lower.
In Java, the entry threshold is higher, that's a fact. But writing a backend in Java (when you know how) is no more difficult than in php, IMHO, even much easier.

Answer 3

Because:
1) Hosting is much cheaper and less demanding.
2) In php, in the case of outsourcing, it is easier and cheaper to find a contractor.
3) If the product has become popular and has "grown", then many consider it inappropriate to rewrite it in real time.
4) there are more de facto php developers than java developers.
