php - Do I really need to do mysql_close()

Question

Do I really need to do mysql_close()? Why or why not?

Is there a trigger that closes the link after mysql_connect even if I don't do mysql_close?

Answer 1

According to the documentation:

Using mysql_close() isn't usually necessary, as non-persistent open links are automatically closed at the end of the script's execution.

Personally, I always like to make sure I pedantically close anything that I open, but it's not required.
