The difference between java and PHP

1. Language comparison

Java supports server-side and client-side. It is a strongly typed language. Any java code needs to be compiled correctly before execution. PHP only supports the server side; it is a dynamically typed language and does not require compiled code.

2. Syntax comparison

1), comments

java supports: double slash (//), /**/ ; PHP supports: double slash (//), # symbol, /**/.

2), case sensitivity

In Java, all function names, keywords, classes, variables, etc. are case sensitive; in PHP, variables are case sensitive , while user-defined functions, classes and keywords are not case-sensitive.

3. Object concept

Java follows the object-oriented concept. So the whole architecture is always well defined.

PHP cannot follow the concept of objects, it is a simple server-side scripting language and it does not have any bindings to follow the defined architecture.

4. Page loading speed

PHP page loading speed is always higher than Java, because the PHP engine does not take up as much load as the JSP engine. Therefore, organizations with complex logic that require some public visual data prefer using PHP.

5. Scope of application

Java is suitable for developing large-scale application systems. The application prospects are relatively broad, the system is easy to maintain and has good reusability. However, PHP is suitable for rapid development, small and medium-sized application systems, low development costs, and can respond quickly to changing needs.

6. Database access

PHP uses different database access interfaces for different databases; while Java accesses the database through JDBC, and the interface for accessing the database is relatively unified.
