PHP logs errors by daily date

File 1: [error.class.php] Rewrite error processing and perform file-type log output. There will be two times, the first is Greenwich time, the second is Beijing time, followed by error information, when used Just include this file. Of course, you can also modify the file format according to your own needs. For example, you can add a mail function later to send it to the email...
File 2: [test.php] test file, which contains error statements for testing.
