Error handling is one of programmings most important issues. It makes your programm stable and prevents it from an inconsistant state. Error checking and handling always boosts your lines of code. So if it has to be this was, how might a convenient strategy for this look like? more »

One of the goals of object-oriented design is to distribute behavior among different objects which encourages reuse. But with larger software the interactions between these objects become more and more complex and we have a situation where each object knows each other. This might end up in a huge monolithic application where the change of one behavior affects a large number of objects which must be adapted too. So the target reuse is reduced by the growth of references. more »

PHP5 new OOP features now allow programmers to create a real object and class based application. But there is one limitation that complicates this development: web based applications rely on a request-response cycle and unlike JSP, PHP does not keep object states between different requests (not talking about hack solutions including sessions or special server extensions). The result is, that objects must be initialized and restored everytime they are needed (maybe based on data stored via GET or POST). So, PHP does not really seem appropriate for developing real OOP applications, beside the use in code libraries. more »
