Article Introduction：It is recommended to use the DatePeriod class to traverse date ranges in PHP. 1. The DatePeriod class was introduced from PHP5.3, and date traversal is implemented by setting the start date, end date and interval. For example, generate a date list from 2024-01-01 to 2024-01-05, which does not include the end date by default; 2. If you need to include the end date, you can adjust the end date or set the INCLUDE_END_DATE parameter; 3. The manual loop method can also complete the traversal using the DateTime object and the modify() method, which is suitable for scenarios where step size needs to be flexibly controlled; 4. Pay attention to the time zone problem that should be explicitly set to avoid the system's default time zone affecting the result; 5. PHP automatically handles leap years

Article Introduction：The difference between include and require in PHP is in error handling: when include error occurs, it will issue a warning and continue execution, suitable for non-core files; when require error occurs, it will trigger a fatal error and stop the script, suitable for core files. 1. include_once and require_once can avoid duplicate inclusion and are suitable for function libraries, configuration files, etc. 2. It is recommended to use __DIR__ to build a stable path to prevent path errors. 3. Sensitive files should be prohibited from external access to prevent information leakage. 4. It is recommended to use require_once for the core class library to ensure that it is loaded without duplication. 5. In terms of performance include/require is slightly faster, but the differences can be made in actual development.

Article Introduction：Writing PHP block comments should be standardized and practical, and is suitable for instructions on large segments of structured code such as functions, classes, and file headers. 1. Usage scenarios include function description, class design intention, complex logical process, copyright information, etc.; 2. The standard format adopts /.../ package, follows the PSR-5 standard, summarizes the first line in one sentence, explains in detail after emptying the line, and uses @param, @return, @throws and other tags to explain the parameters and return values; 3. Practical suggestions include keeping the content concise, aligning and beautiful, avoiding redundancy, and regularly maintaining the consistency of annotations; 4. Common misunderstandings such as inconsistent annotations and code, ignoring the use of tags, and verbose content, you should use the IDE to automatically generate templates to improve efficiency. Standardized block annotations help improve code readability and teamwork
