Here is my test in a PIII 550Mhz 128mb with gentoo:

for ($i = 0; $i <= 9999; $i++) {
$include = 'db_connect.php';
include('include/'.$include);
}

3.623316 seconds
--------------------------------------

for ($i = 0; $i <= 9999; $i++) {
$include = "db_connect.php";
include("include/$include");
}

3.696468 seconds

meatbread.
