Branches

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