Course Introduction：Core points PHP exception is a special class that can be thrown and caught to indicate unexpected events. Unlike unrecoverable errors, exceptions are intended to be processed by the calling code and bubble upward along the execution chain until they are caught. The difference between PHP errors and exceptions is that the error is irrecoverable and occurs in the main execution loop, indicating that there is a problem with the stability of the code or environment; while the exception is recoverable and may occur outside the main execution loop, and does not indicate the system. Unstable. Not all non-successful situations require exceptions to be thrown. Exceptions should be thrown only if they really cannot continue execution. This means that an action that is not a normal operation or standard, an abnormality, deviates from normal and expected situations. Throw a general Exception

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.
