What are the differences between php and java?

What are the differences between PHP and Java? Can I do PHP by learning Java? Most of the friends who ask this question are new to programming. They may want to know which one is better, PHP or Java. In this article, we will introduce the differences between PHP and Java.

Java language

Java is a computer programming language, similar to C, Python and other programming languages Likewise, Java is still widely used today. From the Android mobile apps we use every day to the application server programs of most websites or management information systems, they are all written in Java.

PHP language

PHP is the abbreviation of Hypertext Preprocessor and is a computer script language (Script languages). Scripting languages ​​do not need to generate binary executable files at compile time like programming languages, but directly execute the written PHP code to achieve the effect.

The difference between PHP and Java

1. Technical difference

Java is a pure object-oriented development with powerful functions and many branches. It cannot be done without Java software. C/S or B/S. Functionally speaking, no language can compare with Java. But its advantages are also its disadvantages.

PHP absorbs the advantages of languages ​​​​such as java, c and perl, and focuses on the Internet field. In the WEB field, PHP has unique advantages. There is no language in the WEB field that can compare with PHP.

2. Differences in database access

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.

PHP uses different database access interfaces for different databases, so the database access code is 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.

3. Security Difference

In the face of Java, which is both open source and cross-platform, PHP has lost many advantages, especially in terms of code security.

php development program can be easily modified after others get the code. Programs developed in Java are more secure because they cannot see the complete source code and can only see some compiled class files.

4. Comparison of development costs

PHP is stronger than Java in many aspects of Internet applications, so how can e-commerce products developed by Java compete with PHP products? This lies in the common trend of the Java camp It is the government line, while the PHP camp is taking the national line. Java relies on the words and deeds of university teachers to roar in the Internet world, while PHP relies on its own quality to win the hearts of the people, so it is praised all the way.

The price of software is largely linked to its own cost and functionality. PHP has a low entry barrier, but becoming a master in any aspect is one of the best. The vast majority of programmers who have learned C can easily transform into PHP programmers, which makes PHP programmers as popular as national sports. There are also many experts, and high-quality PHP software products are emerging in endlessly.
In terms of server cost, PHP’s most classic combination is PHP MySQL Apache, and Java is often combined with MySQL Tomcat, JBoss and other software. All software is open source and free, so the investment on the server side is not high.

The learning cost of Java programmers is several times that of PHP. The reason is also very clear. Java itself is not specifically used for WEB development. Therefore, the cost of developing e-commerce in Java is much higher than that of similar software products developed in PHP. However, precisely because the cost of Java development is high, it often takes N times more time and economic cost to develop the same product to achieve the same effect than PHP development. This directly causes a huge waste of time and cost.
