Java seems to enjoy a nice margin over the others. My experience has been that Java developers are not that much in demand -- at least not in the DC area. > Can you show how a simle math routine or for loop routne in a script > language PHP performs faster than a language java? I believe that PHP is not entirely interpreted, at least not all the time. It's unclear to me what Zend brings to the table, honestly. I think what you'll find is that most web apps are very simple, and that the performance characteristics of each language are far outweighed by the performance of network connections (both HTTP and database) as well as any database activity that you are doing in your app. > Can you show how PHP supports <multi-threading>? Yeah, PHP doesn't really do threads. You have to rely on the web server's request processing configuration for concurrency. One advantage of PHP is that pretty much everything is isolated (at least, if you use apache httpd and the prefork MPM), so you generally need not worry about synchronization, etc. -- at least not for objects and such. > Can you show how PHP supports inheritance, polymorphism and encapsulation? I don't think any of that is available in PHP. They do have objects, but they are loosely typed, which sort of blurs definition of "true" OO. Still, I maintain that most webapps are stupid simple, and many don't even write their own code outside of CRUD functions. Since those types of things don't require you to know anything about OO, many developers can get away without an OO language. > Can you show how PHP supports all Java scope (request/page and application)? The request scope /does/ exist, and the page scope implicitly exists since a PHP script can be thought of a one big method (kinda like a vanilla JSP page). The application scope pretty much does not exist. There is a "global" scope, but I am unclear as to the behavior across multiple instances of the PHP engine... for instance, does each script get a separate copy of the "global" variable? Probably. Does that make it not really a global variable? I suppose that depends on your point of view. The bottom line for the whole PHP versus Java thing for me is perceived complexity of a project. If I want it done super fast and super simple, I'll go for PHP. If I want to actually architect something, then I'll turn to Java. My experience has been that as PHP projects grow, they become very difficult to maintain. Not so (or, at least, not so much!) with Java.
