| It requires explicit, this will be used while an object calls its own methods itself. | Java does not. |
| The PHP applications are tends to built from a "run, handle the request, stop running" kind of way. | Java programs tend to be built from a "program runs, stays running, processes requests" kind of way. |
| PHP is interpreted. | Java is compiled to bytecode. |
| PHP is mostly used to dynamically generate Webpages. | Java is mostly used in Applets, mobile software, Enterprise stuff, desktop application with and without GUI (Graphical User Interface), 3D games, Google Web Toolkit and so on. |
| It allows Object Oriented Programming (OOP) as an option which is ignored in the majority projects | In, Java, OOP is default. |
| The PHP String constants are declared using single or double quotes. Double quotes can evaluate variables embedded in the text. | All the Java String constants use double quotes and it has no such variable evaluation. |
| PHP object method calls use the (–>) operator. | Java uses the (.) operator. |
