What is the difference between PHP and JAVA programming?

Php use for the web programming only while java can be used in desktop or application software that is offline.

PHP and Java are both very similar when it comes to the benefits provided, but they are both very different. PHP is a server-side scripting language, while Java is a client side choice.

When you use PHP code, you will execute it in the actual server, while Java will be executed on your client’s computer. This means, if you use Java and the client doesn’t have the right program, such as Java Runtime Environment, your web page won’t show up. With PHP, this isn’t an issue.

Both PHP and Java are widely accepted and used for web development. Some developers will use both codes, depending on what the project call for, while others have their own preference. Java is often known as the industry standard and a bit more robust, while PHP is free and has a larger set of support resources.

 

PHP is also known to be easier to rebuild and customize than Java. It’s also free, while Java is not. However, students of Java can earn a certification, while PHP doesn’t have any type of qualifying level.

 

Choosing PHP or Java isn’t the easiest decision. Both have their advantages and disadvantages. However, for some projects one is certainly better than the other. Most small and medium projects are better with PHP vs. Java. However, larger projects are better with Java vs. PHP.

 

If you’re looking for a free choice, PHP is the right one. Just make sure you get the benefits you need from PHP compared to Java, before you choose the programming language for your needs.

PHP is a server-side scripting language used mainly for web development. It can be easily embedded in HTML files and HTML codes can also be written in a PHP file. The client-side language like HTML are codes are executed on the server whereas HTML codes are directly rendered on the browser while Java is an object-oriented programming language developed by Sun Microsystems that has a virtual machine platform that allows you to create compiled programs that run on nearly every platform. Java has, “Write Once, Run Anywhere”. 

The main difference between PHP and Java is in implementation. Java is compiled into bytecode and run on a JVM. PHP, on the other hand, is an interpreted language. It is first compiled into bytecode and then interpreted by a runtime engine.

Java is a programming language, which has been influenced by the C language. It derives much of its syntax from C and C++, however it has fewer low-level facilities than either. Java is a general-purpose programming language that is designed to have fewer implementation dependencies as compared to previous languages. PHP, on the other hand, is a server-side scripting language that has its main implementation in web development. However, it can be used as a general-purpose programming language.

PHP is a server-side scripting language and java is a general purpose programming language This is the main difference between java and PHP.

PHP is server side scripting language while java is both server side and desktop programming language.

Some differences between Java and PHP:

• Every variable in Java needs to be prepended with a data type. This includes primitive types such as boolean, int, double and char, as well as Object data-types, such as ArrayList, String, and own objects.
• In Java, every variable can only hold a value of its type.
• In Java, equality on objects checks for object identity.
• In Java, arrays are the classic C arrays. They can only hold variables of one particular type, and need to be created with a fixed length.
• Java contains a series of collection Objects, one of which is named ArrayList. ArrayList will act more like PHP arrays.
• In Java, one cannot get the array like syntax; all manipulation must be done through methods.
• In Java, ArrayLists and other collections are implemented with generics.
• Java has no pointers. However, all Objects are actually references, similar to PHP5, and dissimilar to PHP4.
• All method parameters are passed by value in Java.
• The main code entry point in Java is a method to a class, as opposed to PHP where it is not.
• In Java, variable names do not usually start with a sigil ($).
• Class names in Java are case sensitive.
• Strings are not mutable in Java.
• The Java Class library provides a mechanism to implement threads. PHP has no such mechanism.
• PHP methods and functions allow for optional parameters. In Java, a separate method must be defined for each possible list of parameters.
• PHP requires an explicit $this be used when an object calls its own methods. Java does not.
• Java programs tend to be built from a "program runs, stays running, processes requests" kind of way, whereas PHP applications are built from a "run, handle the request, stop running" kind of way.
• Java is compiled to bytecode, PHP is interpreted.
• Java is strong and statically typed, while PHP is rather weakly and dynamically typed.
• PHP is mostly used to dynamically generate Webpages. Java can do that too, as well as Applets, mobile phone software, Enterprise stuff, desktop application with and without GUI,3d games, Google Web Toolkit, etc.
• PHP offers OOP (object oriented programming) as an option that is ignored in most projects. In, Java, OOP is the default.
• String constants in PHP are declared using single or double quotes. Double quotes will evaluate variables embedded in the text. All Java String constants use double quotes and have no such variable evaluation.
• PHP object method calls use the -> operator. Java uses the . operator
• Constructors in Java are named after the class name. In PHP they are called __construct()
• Method overriding and overloading is quite natural in Java but a bit of a kludge in PHP
• PHP code is embedded in what is otherwise largely an HTML document, much like how JSPs work
• In PHP, there is no method overloading, but methods and functions can have optional parameters.
