Does exit() remove a query's overhead & close a database connection?

[floridaflatlander]

I've been wrting this are the bottom of a script

 

header("Location: $home/index.php");
mysqli_free_result($r);
mysqli_close($dbc);
exit(); 

 

I was wondering can exit() remove a querys overhead and close a database connection also, meaning this is the same thing.

 

header("Location: $home/index.php");
exit(); 

 

php.net says exit() "Terminates execution of the script". So maybe it closes the db connection(a script) but leaves a query's overhead??

There is absolutely no need to ever use the free_result () or close () methods/functions on SQL connections, simply because PHP handles all of this automatically when the script ends. This happens both on normal execution end (getting to the end of the file) and when you kill off the script early (via die ()).

This has nothing to do with the functions you use, but is a standard part of the PHP interpreter's clean up routines.

 

So no overhead left, at all.

Never mind.
