The python code in the book Programming Collective Intelligence is aesthetically poor, with unclear naming, bad spacing, errors and some ugly duplication. But it doesn't matter. The algorithms work, the concepts get taught, and you still get to build your own little pageranking search engine in a single chapter. Same deal with PHP. It seems that PHP gets the job done. (I say this never having coded anything significant in PHP.)
