Recently I am interested in the algorithm of converting the solar calendar to the lunar calendar to get the corresponding festivals, so I searched around on the Internet. Not bad, I found a relatively good php class, which implements the algorithm for converting the solar calendar to the lunar calendar (lunar calendar), and the lunar calendar to the solar calendar. At the same time, it can also obtain the zodiac signs, zodiac animals, and the corresponding Chinese names of the lunar calendar, etc. The functions are quite complete, so I would like to share them with you here.
The specific class code is as follows:

class Lunar{ 
  var $MIN_YEAR=1891; 
  var $MAX_YEAR=2100; 
  var $lunarInfo=array( 
    array(0,2,9,21936),array(6,1,30,9656),array(0,2,17,9584),array(0,2,6,21168),array(5,1,26,43344),array(0,2,13,59728),

How to use is as follows:

$lunar=new Lunar();
$month=$lunar->convertSolarToLunar(2013,07,08);//将阳历转换为阴历 
echo '<pre class="brush:php;toolbar:false">'; 
print_r($month);

The printing results are as follows:
Array
(
[0] => 2013
[1] => May
[2] => Thirty
[3] => Guisi
[4] => 5
[5] => 30
[6] => Snake
[7] => 0
)

How to calculate the total number of elements in a PHP multidimensional array?May 15, 2025 pm 09:00 PM

Calculating the total number of elements in a PHP multidimensional array can be done using recursive or iterative methods. 1. The recursive method counts by traversing the array and recursively processing nested arrays. 2. The iterative method uses the stack to simulate recursion to avoid depth problems. 3. The array_walk_recursive function can also be implemented, but it requires manual counting.

What are the characteristics of do-while loops in PHP?May 15, 2025 pm 08:57 PM

In PHP, the characteristic of a do-while loop is to ensure that the loop body is executed at least once, and then decide whether to continue the loop based on the conditions. 1) It executes the loop body before conditional checking, suitable for scenarios where operations need to be performed at least once, such as user input verification and menu systems. 2) However, the syntax of the do-while loop can cause confusion among newbies and may add unnecessary performance overhead.

How to hash strings in PHP?May 15, 2025 pm 08:54 PM

Efficient hashing strings in PHP can use the following methods: 1. Use the md5 function for fast hashing, but is not suitable for password storage. 2. Use the sha256 function to improve security. 3. Use the password_hash function to process passwords to provide the highest security and convenience.

How to implement array sliding window in PHP?May 15, 2025 pm 08:51 PM

Implementing an array sliding window in PHP can be done by functions slideWindow and slideWindowAverage. 1. Use the slideWindow function to split an array into a fixed-size subarray. 2. Use the slideWindowAverage function to calculate the average value in each window. 3. For real-time data streams, asynchronous processing and outlier detection can be used using ReactPHP.

How to use the __clone method in PHP?May 15, 2025 pm 08:48 PM

The __clone method in PHP is used to perform custom operations when object cloning. When cloning an object using the clone keyword, if the object has a __clone method, the method will be automatically called, allowing customized processing during the cloning process, such as resetting the reference type attribute to ensure the independence of the cloned object.

How to use goto statements in PHP?May 15, 2025 pm 08:45 PM

In PHP, goto statements are used to unconditionally jump to specific tags in the program. 1) It can simplify the processing of complex nested loops or conditional statements, but 2) Using goto may make the code difficult to understand and maintain, and 3) It is recommended to give priority to the use of structured control statements.
