php get number of days in month
Article Introduction：How to use PHP to get the number of days in a certain month? 1. Use the cal_days_in_month function, which is the most direct way. The syntax is cal_days_in_month(CAL_GREGORIAN, $month, $year); 2. Use the DateTime class and modify method to create the first day of the month and get the date of the last day by adding one month and subtracting one day. Both methods can correctly obtain the number of days. The former is simple and suitable for simple needs, while the latter is suitable for scenarios where DateTime operations are already available or requires more time to process.

How to implement array LRU cache in PHP?
Article Introduction：Implementing LRU cache in PHP can simulate bidirectional linked list structure by using associative arrays and index arrays. The specific steps are as follows: 1. Create an LRUCache class and initialize an array of capacity, cache and access order. 2. Implement the get method, return the value and update the access order. 3. Implement the put method, add or update elements, and remove the longest-lasting elements if necessary. This method is simple and easy to understand, but performance may decline under large data volumes.

Memory Performance Boosts with Generators and Nikic/Iter
Article Introduction：PHP iterator and generator: a powerful tool for efficient processing of large data sets
Arrays and iterations are the cornerstone of any application. As we get new tools, the way we use arrays should also improve.
For example, a generator is a new tool. At first we only have arrays, and then we gain the ability to define our own class array structure (called iterators). But since PHP 5.5, we can quickly create class iterator structures called generators.
Generators look like functions, but we can use them as iterators. They provide us with a simple syntax for creating essentially interruptible, repeatable functions. They are amazing!
We will look at several areas where generators can be used and explore the need to note when using generators

php compare two dates
Article Introduction：There are two main methods for comparing two dates in PHP: 1. Use the DateTime class for comparison, which is suitable for handling complex date logic, supports direct use of comparison operators, and the code is clear and not prone to errors; 2. Use the strtotime() function to convert dates to timestamps and compare them, which is suitable for simple scenarios but pay attention to format limitations. In addition, the time zone and date formats are also required, and the null value processing is done to ensure that the comparison results are accurate and reliable.

php convert yyyy-mm-dd to dd-mm-yyyy
Article Introduction：There are three main ways to convert date formats in PHP. 1. Use date and strtotime to combine to be suitable for simple conversion in standard formats, such as converting yyyy-mm-dd to dd-mm-yyyy; 2. Use the DateTime class to be suitable for handling complex scenarios such as addition and subtraction days or object-oriented style development; 3. Non-standard formats can be regularly extracted or introduced into third-party libraries such as Carbon to parse and format output.

php regex performance
Article Introduction：The key to PHP regular expression performance optimization is to reduce the number of backtracking and matches; 1. Avoid greedy matching and backtracking, use non-greedy patterns, avoid nested quantifiers, and reduce the use of capture groups; 2. Compile regular expressions in advance, and use static variables or class constant storage to reduce the overhead of repeated parsing; 3. Prioritize string functions to replace simple matching tasks, such as strpos, substr, etc. to improve efficiency; 4. Use anchor points and boundary control characters such as ^, $, and \b to limit the matching range to speed up the engine judgment.

Re-Introducing Symfony Console - CLI PHP for the Uninitiated!
Article Introduction：Core points
Symfony Console is a standalone package that provides a simple framework for creating command line tools, which is useful for repetitive tasks such as data migration, importing, or creating cron jobs.
To create a new command, you need to make the file executable. This can be done by creating a console file in the project root directory, ensuring the file is executable, and defining the console application.
You can use Symfony's CommandTester class to test commands, which provides special input and output classes to test commands without the command line.
Symfony Console is installed using Composer (the dependency management tool in PHP). It provides a simple

php get start of week
Article Introduction：There are several ways to get the start time of a week in PHP: 1. Use the DateTime class to get the Monday of this week, which is suitable for situations where Monday is the week; 2. Customize the start day of the week, and dynamically set Monday or Sunday as the starting point by judging the current week; 3. Get the start time of the week where the specified date is, which is suitable for processing data that is not the current date; 4. Use strtotime to quickly implement it, which is suitable for simple scenarios but is not recommended for complex logic. You can choose the appropriate method according to project needs, and the DateTime class is clearer and more reliable.
