note 127242 added to function.spl-autoload

Both namespaces and class names are case insensitive. This can cause problems with autoloading in OS/filesystems that _are_ Consider this code: <?php declare(strict_types=1); set_include_path(get_include_path() . PATH_SEPARATOR . 'class/'); spl_autoload_extensions('.class.php'); spl_autoload_register(); $foobar = new \foo\bar(); ?> and a class file /class/foo/bar.class.php: <?php declare(strict_types=1); namespace Foo; class Bar { public function __construct() { echo 'Map constructed'; } } ?> this will work fine regardless of a case sensitive or not case sensitive OS/FS. A file called ./class/Foo/Bar.class.php will only be found on a not case sensitive situation as the default class loader will mb_strtolower() the class name to find the class filename. Btw. this content of a class file will be equivalent to the one above: <?php declare(strict_types=1); namespace foo; class bar { public function __construct() { echo 'Map constructed'; } } ?> The class /foo/bar and /Foo/Bar are one and the same thing. ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.12.131 (proxied: 83.97.81.249) ---- Manual Page -- https://php.net/manual/en/function.spl-autoload.php Edit -- https://main.php.net/note/edit/127242 Del: integrated -- https://main.php.net/note/delete/127242/integrated Del: useless -- https://main.php.net/note/delete/127242/useless Del: bad code -- https://main.php.net/note/delete/127242/bad+code Del: spam -- https://main.php.net/note/delete/127242/spam Del: non-english -- https://main.php.net/note/delete/127242/non-english Del: in docs -- https://main.php.net/note/delete/127242/in+docs Del: other reasons-- https://main.php.net/note/delete/127242 Reject -- https://main.php.net/note/reject/127242 Search -- https://main.php.net/manage/user-notes.php
