What are the advantages of java over php?

There are many popular programming languages ​​​​at present. Many people want to switch careers to learn Web programming, but they are entangled in choosing PHP or Java. Which of these two languages ​​​​is more suitable for Web development? , today I will introduce to you the advantages of java over php:

1. Database access advantages

PHP uses different database access interfaces for different databases, so the database Access codes are not very versatile. For example: a web application developed in Java only needs very few modifications to be transferred from a MySQL database to an Oracle database. PHP requires a lot of modification work.

Java accesses the database through JDBC and conveniently accesses the database through database drivers provided by different database vendors. The interface for accessing the database is relatively unified.

2. Distributed multi-layer architecture advantages

PHP can only implement a simple distributed two-layer or three-layer architecture, while Java cannot achieve this It is relatively powerful and can implement multi-layer network architecture. The database layer (persistence layer), application (business) logic layer, and presentation logic layer are separated from each other, and now different layers are supported by some mature development frameworks.

3. Source code security advantages

The source code of programs developed by PHP is public, and others can use it after getting the program developed by PHP. Revise. For programs developed in Java, what users get in the end are just some compiled classes, and the complete source code cannot be seen, so the security is high.

4. Employment advantages

Java has a wide range of employment opportunities and a large market demand for employment. Java mostly develops large-scale systems, so large enterprises are in great need of Java technical talents.
