I may be wrong, but FWIW I don't think there is a detailed PPL syllabus in the sense you are asking. I base this on various JAR-FCL documents I've trawled through over the years, more on the post-PPL ratings and licenses.
In general, they don't seem to publish a detailed syllabus beyond the high level "list of subjects". This is also true in the ATPL theory. The detailed syllabus is de facto what is in the quasi-public domain databanks of questions and in the standard texts.
