You should install and use a debugger, e.g. Xdebug and netbeans as ide. Until then you can use an echo/printf debugger, i.e. Print some more debugging information like the actual query sent to mysql, the number of results, .... (Don't forget to remove the debug output or make it conditional in some way.).
