I'm very surprised by the results
of Regis tests. And a bit disappointed by them ! doesnt php
use any cache before including files ? it's pretty amazing.

Not that however that a having a lot of require and
include is not really a problem when this is done onto a
file that exists.
Problem is above all for is_file or require or include on
file that does not exists.
But reducing time is always welcome.
Not that for require on top of page, adding a test on a
class is useless because we know that file was not loaded.

Hi
I
did a little test performance between
require_once and
class_exists.
we gain 50% performance gain
using class_exists
see the
figures below (tested separately)
class_exists
condition will
check only if the class
is already included.
A
require_once will
read the file, read
file, create the hash,
the hash compare
to other hashes,
and finally decide.
$t1 = microtime(true);
$nbloops = 3000;
$file1 = 'compta/facture/class/facture.class.php';
$file2 = 'societe/class/societe.class.php';
$file3 = 'comm/propal/class/propal.class.php';
for ($i=0;$i<$nbloops;$i++){
if (! class_exists('Facture'))
require $file1;
if (! class_exists('Societe'))
require $file2;
if (! class_exists('Propal'))
require $file3;
}
echo 'script executed in '.(microtime(true)-$t1).' s';
//script executed in 0.0548310279846 s
for ($i=0;$i<$nbloops;$i++){
require_once $file1;
require_once $file2;
require_once $file3;
}
echo 'script executed in '.(microtime(true)-$t1).' s';
//script executed in 0.134128093719 s
Cordialement,
