Below are the source code lines that represent each code path as identified by Xdebug. Please note a path is not necessarily coterminous with a line, a line may contain multiple paths and therefore show up more than once. Please also be aware that some paths may include implicit rather than explicit branches, e.g. an if statement always has an else as part of its logical flow even if you didn't write one.
