Overview

Java is an object-oriented programming language that can be used to write cross-platform applications or web-based applications. The Java language is class-based, object-oriented, readable and supports both the server side and the client side. It can be compiled or interpreted, its editor can convert the source code into bytecode, and then generate the corresponding machine code, the machine diamante can be run directly by the machine running the Java program.

PHP is a widely used server-side scripting language for creating dynamic interactive sites without compiling code. PHP is often used to develop management systems, which can provide good search engine rating and accessibility for managed server providers.

Difference

Comments. Both support double slashes (/ /), / * / comments, and PHP can also be annotated with the # symbol.

Letters are upper and lower case. Java is case-sensitive; in PHP, other user-defined functions, classes, and keywords are not case-sensitive, except for variables.

Loading speed. The PHP engine does not take as much load as the JSP engine, so the page loading speed of PHP is higher than that of Java.

Database access is different. Java accesses the database through JDBC, and the access interface is more unified, while PHP uses different access interfaces to access the database.

It's clear. PHP is open source and less secure than Java.

Application. Java is used to develop large-scale application systems. PHP is suitable for developing small and medium-sized application systems.
