I encountered a strange problem, the PHP code contains//such comments, include failed

PHP failure include

I have a strange problem, the PHP code contains//such comments, can not include
I was developed two times, the server above the original program with//comment on the no problem

But I downloaded the code from the server to the local, all the programs, after importing Eclipse, each line will be followed by a blank line

Later I changed//comments to/***/this is good.

Here is my post phpinfo information, hope the Great God Guide
