Using spl_autoload() not able to load class

문제
I'm playing around with the SPL autoload functionality and seem to be missing something important as I am currently unable to get it to work. Here is the snippet I am currently using:
// ROOT_DIRECTORY translates to /home/someuser/public_html/subdomains/test
define('ROOT_DIRECTORY', realpath(dirname(__FILE__)));
define('INCLUDE_DIRECTORY', ROOT_DIRECTORY . '/includes/classes/');
set_include_path(get_include_path() . PATH_SEPARATOR . INCLUDE_DIRECTORY);
spl_autoload_extensions('.class.php, .interface.php, .abstract.php');
spl_autoload_register();
When I echo get_include_path()
I do get the path I expected:
// Output echo get_include_path();
.:/usr/lib/php:/usr/local/lib/php:/home/someuser/public_html/subdomains/test/includes/classes/
However when I run the code I get this error message:
Fatal error: spl_autoload() [function.spl-autoload]: Class Request could not be loaded in /home/someuser/public_html/subdomains/test/contact.php on line 5
Request.class.php is definitely in the /home/someuser/public_html/subdomains/test/includes/classes/ directory.
What am I missing?
해결책
There is a comment (anonymous) on http://www.php.net/manual/en/function.spl-autoload-register.php#96804 that may apply to your problem: spl_autoload_register() doesn't seem to play nice with camelcase, and in your case could be trying to find request.class.php instead of Request...

The path where the class is supposed to be seems not to match the path were you expect them. Compare
.:/usr/lib/php:/usr/local/lib/php:/home/someuser/public_html/subdomains/test/includes/classes/
with
/home/someuser/public_html/subdomains/test/
The difference is, that your class is not in includes/classes/
as your SPL requires it but a few directories above.
I got a similar error message but my issue was different. My error message looked like
PHP Fatal error: spl_autoload(): Class Lib\Lib\Regex could not be loaded in /dir1/dir2/lib/regex.php on line 49
It turned out I forgot to remove the Lib\
from Lib\Regex
inside the Regex class definition itself. I had something like the following:
namespace Lib;
class Regex {
...
public static function match($pattern, $str) {
$regex = new Lib\Regex($pattern);
...
}
}
