PHP strcmp vs == for string comparison

Course Introduction:To compare PHP strings, you should choose different methods according to your needs, and you cannot blindly use ==. Strictly compare it with ===, and strcmp() is used for dictionary order comparison. 1.==Unreliable, type conversion will cause unexpected results, such as '0e123'=='0' is true; 2.=== is the safest comparison method, the judgment is completely consistent and the type is not converted; 3.strcmp() is used to compare strings in dictionary order, returning -1, 0, and 1 to represent size relationships, and is case sensitive; 4. Safe scenarios must avoid ==, and performance === is better. Pay special attention to traps when comparing null or boolean values.

Go language tutorial manual

Course Elementary  27465

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.
