"This isn't exactly PHP's fault. Yes, the language is feature-rich, and it has just enough idiomatic elasticity to distinguish one programmer's work from another's. In this regard, PHP is similar to Perl, which is one of the reasons some people love it (and others despise it). Any experienced PHP developer who has reviewed a legacy PHP project can easily detect the work of different developers over the phases of the project—it's as though you were an archaeologist peering into a deep vault and witnessing the march of different cultures in their respective epochs."
