Wow thats fast!
On my machine i get these results:
Win32 (PHP 5.2.1 CLI)
require_once - 1.7735 sec
myrequire_once - 1.0973 sec
I made two benchmarks one with relative paths and one with full paths.
The full paths:
<?
$start_time = microtime(true);
define('BASEPATH', dirname(__FILE__).'/');
function myrequire_once($file)
{
static $loaded = array();
if (!array_key_exists($file, $loaded))
{
$loaded[$file] = 1;
require $file;
}
}
for ($i=0;$i<1000;$i++) {
// require_once(BASEPATH.'manyClasses/'.$i.'.class.php');
myrequire_once(BASEPATH.'manyClasses/'.$i.'.class.php');
}
$execution_time = microtime(true) - $start_time;
echo number_format($execution_time,4)."\n";
?>
Here the benchmarks with relative paths:

now I only have one windows system to test on but from this test it
seems that the full path version is slower on windows then the relative
paths. Which struck me as odd so I actually reran the tests several times.
The myrequire_once function is generally slower across my test cases
then require_once.
