PHP静态计数器？

Question

I'm trying to create a script that will retain a count, even when it is called multiple times. This is to give unique IDs to certain things lines that the script is writing to a file.

For exmaple:

Monday I call the script and make 2 lines. The script gives ID 1 and 2 to those lines.
Friday I call the script again and make another line. The script gives ID 3 to this one.
etc

Answer 1

I would recommend using MySQL's auto increment feature.

Otherwise, store a flat file to store a running count (and lock it when in use to avoid concurrency issues).
