Course Introduction：How to efficiently manage the build, test, and deployment process is a common problem when developing a PHP project. I've encountered a dilemma in a project: Every time a new version is released, I have to manually perform a series of complex operations, including running tests, generating documentation, and deploying code. This is not only time-consuming and labor-intensive, but also prone to errors. After some exploration, I found Phing, a powerful PHP project building tool, which was easily installed and used through Composer, completely solving my problem.

Course Introduction：The running mechanism of Java programs mainly includes compilation into bytecode, JVM execution and automatic memory management. First of all, Java code is compiled into platform-independent bytecode (.class file) through javac, realizing "write once, run everywhere". Next, the JVM loads the bytecode and interprets it by the execution engine or compiles it into machine code through JIT. At the same time, the JVM is also responsible for class loading, memory management and garbage collection. Then, the class loader (ClassLoader) loads class files from disk or network, and the runtime data area includes heap, stack, method area, etc. for data storage for program operation. Finally, the garbage collection mechanism automatically recognizes and frees object memory that is no longer in use, avoiding the complexity of manual memory management. The whole process starts

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
