Course Introduction：In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

Course Introduction：Core points PHP collection class is an object-oriented alternative to traditional array data structures, providing a structured way to manage object groups and providing built-in data manipulation methods. The basic collection class should provide methods for adding, retrieving, and deleting items, as well as methods for determining whether the collection size and given keys exist in the collection. Collection classes can improve performance, especially when working with large datasets, because they use delayed instantiation, creating elements in the array only when needed, saving system resources.

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.
