Navigating the Nuances of Character Encoding in PHP
Article Introduction：To correctly handle character encoding in PHP, it is necessary to ensure that UTF-8 is used consistently at all levels; 1. Understand the importance of UTF-8, which is a web standard that supports multilingual and emojis; 2. Set correct encoding in the PHP environment, including saving the file as BOM-less UTF-8, using the mbstring function instead of ordinary string functions, and setting mb_internal_encoding and mb_http_output to UTF-8; 3. The database needs to use utf8mb4 character set and corresponding sorting rules, specify CHARACTERSETutf8mb4COLLATEutf8mb4_unicode_ci when creating the table, and pass SE

C typeid example
Article Introduction：typeid is an operator used in C to obtain runtime type information and must contain a header file; 1. It can be used for type comparison of basic types. typeid(a).name() returns the compiler-related encoding name, and the types can be judged by comparison. 2. When used in polymorphic classes, only the class defines a virtual function to correctly obtain the dynamic type of the object pointed to by the pointer, otherwise only the static type will be returned; 3. In GCC/Clang, abi::__cxa_demangle can be used in GCC/Clang to convert the encoding name to a readable type name, but this method is a non-standard extension and is not applicable to all compilers; typeid is suitable for debugging and logging scenarios, and should not be used excessively in performance-sensitive code.

Refactoring Legacy PHP: A Practical Guide to Eliminating $GLOBALS
Article Introduction：To eliminate $GLOBALS in PHP, it should first analyze its usage and then replace global variables with dependency injection, configuring objects, and step-by-step refactoring. 1. Use grep and other tools to find out all the usage of $GLOBALS and record the key names and locations; 2. Replace global variables such as database connections and configurations with explicit dependencies, such as injecting PDO or Config objects through constructors; 3. Create service classes (such as Logger, UserService) to encapsulate functions to avoid function dependence on global state; 4. Centrally manage the configuration, load from the configuration file returning the array, and inject the required classes; 5. Reconstruct the database in a small way, replacing a $GLOBALS reference at a time, and test to ensure consistent behavior; 6. Beware of including
