note 126640 added to language.oop5.basic

BEWARE! Like Hayley Watson pointed out class names are not case sensitive. <?php class Foo{} class foo{} // Fatal error: Cannot declare class foo, because the name is already in use ?> As well as <?php class BAR{} $bar = new Bar(); echo get_class($bar); ?> Is perfectly fine and will return 'BAR'. This has implications on autoloading classes though. The standard spl_autoload function will strtolower the class name to cope with case in-sensitiveness and thus the class BAR can only be found if the file name is bar.php (or another variety if an extension was registered with spl_autoload_extensions(); ) not BAR.php for a case sensitive file and operating system like linux. Windows file system is case sensitive but the OS is not and there for autoloading BAR.php will work. ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.85.242 (proxied: 83.97.87.182) ---- Manual Page -- https://php.net/manual/en/language.oop5.basic.php Edit -- https://main.php.net/note/edit/126640 Del: integrated -- https://main.php.net/note/delete/126640/integrated Del: useless -- https://main.php.net/note/delete/126640/useless Del: bad code -- https://main.php.net/note/delete/126640/bad+code Del: spam -- https://main.php.net/note/delete/126640/spam Del: non-english -- https://main.php.net/note/delete/126640/non-english Del: in docs -- https://main.php.net/note/delete/126640/in+docs Del: other reasons-- https://main.php.net/note/delete/126640 Reject -- https://main.php.net/note/reject/126640 Search -- https://main.php.net/manage/user-notes.php
