Article Introduction：Handling dates and times in any programming language is often a simple and trivial task until the time zone needs to be supported. Fortunately, PHP has a powerful set of date/time tools that can help you deal with various time-related issues: Unix timestamps, format dates for human reading, display dates with time zones, calculate the time difference between now and the second Tuesday of next month, and more. This article will introduce the basics of PHP's time functions (time(), mktime(), and date()) and its object-oriented counterparts, then learn about MySQL dates and show you how to make them work perfectly with PHP. Main gains Use PHP's powerful date and time functions, such as time() and mktime(

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：Best practices for cross-browser date input This article explores the challenges and best solutions for implementing date input fields in various browsers. Due to inconsistent browser support and neglect of lang attributes, we need a robust solution to deal with date formats, UTC/local time issues, and differences between different browsers. Key points: The browser's support for and lang attributes is uneven, resulting in the inability to display input widgets in non-native languages. Many JavaScript solutions attempt to improve support for date input, but few scripts can handle two different date formats that display and save data at the same time. Datepicker for jQuery UI is a well-tested and supported

Article Introduction：Modules are better than headerfiles because they solve problems such as duplicate inclusion, slow compilation speed, and macro pollution. 1.Modules adopts a mechanism of compiling once and importing multiple times, avoiding the problem of re-parsing header files every time they are compiled, improving construction efficiency; 2. The modules are naturally isolated from interfaces and implementations, reducing naming conflicts and unnecessary symbol exposure. Writing a simple module requires an interface unit and an implementation unit: 1. The interface unit starts with exportmodulename; and exports the declaration; 2. The implementation unit starts with modulename; and contains specific implementation code. Note when using modules: 1. The module interface must be compiled before the code that references it; 2.

Article Introduction：Although GitHub is an excellent solution for code collaboration and repository management, some individuals and companies prefer to maintain code in the intranet for security reasons. It is easy to provide warehouse access on the local intranet, but it is not that simple to have a friendly interface to interact with these warehouses and simplify team collaboration. Git comes with a web interface gitweb, but it is not elegant and modern enough, it is difficult to view changes, authors and time, and browsing workspaces is also quite cumbersome. Some other solutions are difficult to install or the interface is not friendly enough. Recently I discovered GitList, a free and open source Git repository viewer. Its interface is very similar to GitHub, but it focuses more on conciseness and clarity. This article will guide you to set up your own Git repository

Article Introduction：The major revisions of iOS 18 and iPadOS 18 Photos App have caused confusion and dissatisfaction among users. Many users are used to sorting old photo apps. The new version is sorted by the creation time of film and video rather than dates, which leads to some problems. For example, if you receive photos shared via airdrop a week ago, these photos will be placed in an older time period and are difficult to find, rather than appearing at the bottom of the album as most users expect. Fortunately, iOS 18 allows you to change the sort of photos to "Recently Added" instead of "Shot Date" (i.e. when you create it). A lot of complaints about the new photo app are solved with just a simple tweak. How to sort photos by adding date instead of creating time in iOS 18

Article Introduction：There are key differences in syntax and functionality between OracleSQL and ANSISQL, which are mainly reflected in the use of ||, external connections using ( ) operators, DECODE functions instead of CASE expressions, and unique date and time functions. Specifically, it includes: 1. Oracle uses || for string splicing, which complies with ANSI standards but is different from MySQL or SQLServer; 2. Oracle traditionally uses ( ) operator to achieve external connection, while ANSI uses LEFT/RIGHT/FULLJOIN; 3. Oracle's DECODE function provides functions similar to simple CASE but has different structures; 4. Oracle provides SYSDATE, ADD_M

Article Introduction：There are two main ways to create threads in Java: inherit the Thread class and implement the Runnable interface. 1. To inherit the Thread class, you need to define a subclass and overwrite the run() method, and start a thread through start(), which is suitable for simple tasks but is limited by the Java single inheritance mechanism; 2. To implement the Runnable interface to separate tasks from threads, run Runnable instances through Thread, support more flexible design and can be used in combination with thread pools; in addition, Java8 can also use Lambda expressions to simplify the writing of one-time tasks. Be careful not to call run() directly, avoid repeated starts, reasonably naming threads, and understand the priority scheduling mechanism.

Article Introduction：There are three main ways to transfer files from Mac and PC: LAN sharing is suitable for frequent transmission under the same Wi-Fi, with fast speeds and no dependence on third-party software; cloud services such as GoogleDrive, Dropbox, etc. are suitable for occasional transmission and pay attention to security and synchronization; USB or mobile hard disks are suitable for one-time transmission, simple operation, but attention to format compatibility and interface speed. When choosing, you should consider comprehensively based on the frequency of use, network conditions and security needs, and pay attention to issues such as SMB settings, account login and file system format to avoid transmission obstacles.

Article Introduction：In C, there are three main ways to pass functions as parameters: using function pointers, std::function and Lambda expressions, and template generics. 1. Function pointers are the most basic method, suitable for simple scenarios or C interface compatible, but poor readability; 2. Std::function combined with Lambda expressions is a recommended method in modern C, supporting a variety of callable objects and being type-safe; 3. Template generic methods are the most flexible, suitable for library code or general logic, but may increase the compilation time and code volume. Lambdas that capture the context must be passed through std::function or template and cannot be converted directly into function pointers.

Article Introduction：There are three main methods for verifying the validity of dates in PHP: 1. Use the checkdate function to verify the Gregorian date, which is suitable for the standard MM/DD/YYYY format, which can judge leap years but does not support non-Gregorian calendars; 2. Use DateTime::createFromFormat to verify specific formats such as 'YYY-MM-DD', 'd/m/Y', etc., which are more flexible and can be used in combination with time verification; 3. Make loose judgments on timestamps or fuzzy formats through strtotime, but are not suitable for strict verification. Select the appropriate method according to the scene: select checkdate for the simple date, use DateTime::createFromFormat for complex formats, and use strt for temporary judgment
