From the point of view of the development space, Java's development space is greater than PHP, for the following reasons:

First, Java has a more sound ecological. Java language in addition to the field of Web development has been widely used, in the mobile Internet, cloud computing, big data, embedded development and other fields also have a wide range of applications, compared to the PHP is mainly used in the field of Web development. There is a clear advantage over PHP, which is mainly used in the field of Web development. Moreover, there are a large number of platform-type products based on Java development, such as Oracle series products, Hadoop platform, etc., which lays a solid foundation for the development and application of Java.

Second, the performance of Java is better than PHP. in the three traditional solutions in the field of Web development (Java, Python, PHP), Java is known for its performance, Python is known for its simplicity, and PHP is known for its flexibility. This has led to the fact that most of the large Internet platforms with high performance requirements are developed in Java, and the trend remains unchanged from the present.

Third, Java is still active in the era of big data.Java, as one of the common languages for big data development, still has a large number of applications in the era of big data, for example, the development under Hadoop uses a large number of Java languages. The future of big data will have a huge space for development, and Java will also be widely used along with the development of big data.

Besides the above reasons, Java is also a common language for development in the field of artificial intelligence. The future must be the age of intelligence, so the future application of the Java language will continue for a long time. So in combination of the above factors, Java has more scope for future development as compared to PHP.

At present, both Java and PHP have a large number of market demand, and the PHP language, as one of the main languages for Web development, also has a large number of application scenarios. Compared to Java, learning PHP is a bit easier. From the perspective of employment, learning PHP is also a good choice at the moment.

I've been using Java for a long time, and I've also been using PHP for a while (to do app back-end processing), and I'll be writing some articles about Java and PHP in the headline one after another, so interested friends can
