Article Introduction：In PHP, there are three ways to convert month numbers to names: use date function to match mktime, manual array mapping, and use the Carbon library. 1. Use date and mktime to obtain English or localized month names through system functions; 2. Array mapping is suitable for fixed mapping relationships, flexible control and does not depend on the environment; 3. The Carbon library is suitable for modern framework projects, supports internationalization and chain calls, which is more elegant and convenient.

Article Introduction：PHP date format conversion is mainly implemented in two ways. First, use the combination of date() and strtotime() functions, which are suitable for most standard format conversions, but have limited support for non-standard formats; second, use the DateTime class to deal with more complex scenarios, such as time zone conversion and multilingual support, which has stronger readability and fault tolerance; in addition, you also need to master common format characters, such as Y represents a four-bit year, m represents a month with a leading zero, and d represents a date with a leading zero, etc.; it is recommended to use date() in simple scenarios, and DateTime is preferred if it involves time zone or internationalization, and pay attention to verifying the legitimacy of the input.

Article Introduction：To handle dates and times in SQL, you need to master the following techniques: 1. Use EXTRACT to extract the date part, such as year, month, day, etc., for easy group statistics; 2. Use INTERVAL to add and subtract dates, which are suitable for calculating deadlines or time difference; 3. Use ATTIMEZONE to process time zone conversion to ensure the accuracy of multi-time zone data; 4. Generate consecutive date sequences through generate_series in PostgreSQL to facilitate completion of report dates. Different databases such as MySQL and PostgreSQL have slightly different functions. You need to pay attention to compatibility when operating. Mastering these techniques can improve time processing efficiency and accuracy.

Article Introduction：Master the axis operations except / and //, such as parent::, following-sibling:: and preceding::, and use //node()[self::sectionorself::chapter] to match multiple tags; 2. Use predicates to perform complex filtering, such as position, multi-condition combination and function judgment, for example //log[substring(@timestamp,1,10)='2024-05-20'] to filter by date; 3. Correctly handle the namespace, you need to register the prefix and URI mapping in the parser, such as //ns:item, you need to configure ns→http://example.com/ns

Article Introduction：date_modify is a method in PHP used to modify the date and time represented by the DateTime object, allowing the addition and subtraction of dates. 1. Its basic usage is to adjust the date by passing string parameters such as 1day or -2months; 2. It can be used in combination with multiple time units, such as 1week2days, which is suitable for periodic task arrangement; 3. It supports natural language expression, such as nextMonday, which is convenient for processing user input; 4. When using it, you need to pay attention to directly modifying the original object, the object should be cloned to retain the original value, and pay attention to boundary situations such as the end of the month.

Article Introduction：To deal with region-related date formatting in PHP, the core is to use the locale-aware method to output dates that match the user's language and culture. There are two main methods: one is the traditional function strftime() combined with setlocale(), such as setlocale(LC_TIME,'de_DE.UTF-8'); echostrftime('%A%d.%B%Y',strtotime('2025-04-05')); but attention should be paid to the differences in different systems and global impacts of regional names. The second is the recommended IntlDateFormatter class, such as $formatter=newIntlDateForm

Article Introduction：Use usort() to solve the multi-condition sorting problem of complex data in PHP. 1. Define the sorting logic through a custom callback function and use the operator to return -1, 0 or 1; 2. When implementing multi-level sorting, first compare the main fields, and if equal, enter the secondary fields step by step; 3. Create dynamic callback functions to flexibly adjust the sorting fields and directions according to the configuration array; 4. Support complex types such as date and calculated values, but preprocessing and time-consuming operations are required to improve performance; 5. If the original key name is required, uasort() should be used instead of usort(); finally, efficient and maintainable intelligent sorting is achieved through structured callbacks, and the end is complete.

Article Introduction：When writing PHP comments, you should clearly explain the code logic rather than surface operations. Use //, # or // to maintain the style uniformity. Single-line comments are used for in-line explanations or temporary masking of code. For example, // This is a simple assignment, multi-line comments are used to explain complex logic or function functions. For example, the function verifys the function of user input format, and the comment content should explain "why" rather than "what to do", such as explaining the reason for judging the date format before strtotime. At the same time, the comments need to be updated synchronously with the code modification to avoid inconsistent with the actual logic. Good comment habits can improve code readability and maintenance efficiency.
