Difference Between Java and PHP

Java and PHP are both the two most popular programming languages. There are so many differences and similarities between both of them. Let's understand both of them one by one, and after that, we understand the similarities and differences between them.

Java vs PHP


Java is one of the widely used open-source programming languages that follow OOPs concepts. The Java code is compiled into byte code and run on a JVM. The language developed by Sun Microsystems has a VM platform that allows us to create compiled programs that we can run on any platform. So, Java code follows the concept of "Write Once, Run Anywhere".

Let's take an example to understand how we can write the code in Java:


Java vs PHP


Unlike Java, PHP is a server-side scripting language. We mainly use PHP for developing and designing web applications. Two main characteristics of PHP are as follows:

  1. PHP code can be easily embedded in the html code.
  2. We can also write the html code in the PHP file.

PHP codes are executed on the server because it is a server-side programming language. The HTML code embedded in the PHP file can be directly rendered on the browser after executing the PHP file on the server.

Similarities Between Java and PHP

These are the following similarities between Java and PHP:

  1. Open-source
    Java and PHP are both freely available in the market to use. There is no need to pay an amount to use them. Both Java and PHP can be modified and redistributed by users.
  2. Follows OOPs Concepts
    Java and PHP both follow the concepts of OOPs such as Inheritance, Polymorphism, and Encapsulation, etc. The languages that follows OOPs are easy to understand. We can reuse the code in other programs to utilize time and memory.
  3. Syntax
    The process of defining data members, member function, classes, and looping structures is the same in both programming languages. It helps the developer to work on a cross-platform.
  4. Easy to learn
    Both the languages are very simple and easy to learn even for the fresher also. Learning PHP and Java is simple if we have knowledge of the syntax of both.

Differences Between Java and PHP

The following table describes thekeydifferences between Java and PHP:

Java PHP
Java is an object-oriented, general-purpose programming language. PHP is an object-oriented server-side scripting language.
Java is compiled and strongly-typed language. PHP is a dynamic and weak typed language.
Java provides a rich set of APIs in comparison to PHP. PHP provides less API in comparison to JAVA. In PHP, It is very easy to rebuild and customize APIs.
Method overloading and method overriding are supported in Java. PHP doesn't support method overloading and method overriding.
Java provides several packages and deployment utilities. PHP has no packaging concept.
For creating complex and large applications, Java is very fast. For creating web pages, it is very fast.
It is a compiled type programming language. PHP is an interpreted language.
In Java, OOP is available by default. PHP offers OOP as an option.
For complex and large applications, Java is good to use. PHP is not good for large and complex projects.
Java is a very secure programming language in comparison to PHP. PHP provides less security as compared to Java.
