Course Introduction：Optimizing the for loop performance of PHP requires a number of measures: 1. Cache loop conditions, such as pre-storing the count() result to avoid repeated calls per iteration; 2. Prioritize foreach when no manual control of the index is required, because it is more efficient and less error-prone; 3. Move unchanged operations in the loop out of the loop, such as configuration acquisition or object creation; 4. Use references (&) to prevent value copying when processing large arrays, and improve memory efficiency; 5. Avoid string splicing in the loop, and first store fragments into the array and then merge with implode(); 6. In a very small number of performance-critical scenarios, loop expansion can be considered to reduce the number of iterations but sacrifice readability; 7. Always pass Xdebug, Blackfire or mic

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.
