How do I use the beforeAction() and afterAction() methods in a controller?
Article Introduction：beforeAction() is used in Yii2 to run logic before the controller action is executed.

php format duration in hours minutes seconds
Article Introduction：To convert the total number of seconds to the hour:minute:second format, PHP provides two common methods. The first is to use basic mathematical operations: obtain the hours by dividing by 3600, continue to calculate the minutes and seconds after taking the modulus, and finally format the output with sprintf(); the second is to use the DateInterval class to achieve object-oriented formatting with DateTime. If the time length of more than 24 hours is required, it is recommended to calculate the hour part by yourself to avoid the limit of %H to only display the number of hours within the day. For example, 90061 seconds can be converted to 25:01:01. Select the right method according to your needs to complete the conversion.

Article Introduction：It is always easier to process sorted data to extract specific information, otherwise you have to iterate through each element of the array one by one.
For example, suppose you store the grades of different students in an array or table. If the data are not sorted by the grades obtained, you must check the grades of each student in the class to determine who gets the highest and lowest scores. If the table has been sorted from low to high by grades, you can know the lowest score by simply checking the first student’s grades.
This article will introduce the following PHP array sorting methods:
Sort arrays by value
Sort associative arrays
Sort array elements by value using user-defined functions
Sort array by key
Sort PHP multidimensional arrays
