Logging is vital. you can not only record error information, but also record a lot of information, such as order flow.... using php file operations to achieve custom logging is extremely simple!

Take a look at the following simple php code:

[12:31:20] non-numeric characters [12:31:43]

A simple function enables logging and recording the date of adding each log. it is not difficult to find that the following three steps are used to implement custom logging:

2. append logs

3. close the file

You can complete the above php code!
