note 120937 added to language.oop5.constants

It may be obvious (but I haven't found it written literally nowhere), that checking if the class constant is defined (using defined() function) or reading it's contents (using constant() function), also tries to autoload the class in which the constant is defined (if the class is not already loaded). At least in my php 5.5.9. <?php if (defined('vendor\\package\\SomeClass::MAJOR')) { // autoloading here echo 'Oh, I know how to recognize major stuff!'. PHP_EOL; } $loadedState = constant('vendor\\package\\OtherClass::LOADED'); // autoloading here ?> ---- Server IP: 72.52.91.14 Probable Submitter: 213.155.166.101 ---- Manual Page -- http://php.net/manual/en/language.oop5.constants.php Edit -- https://master.php.net/note/edit/120937 Del: integrated -- https://master.php.net/note/delete/120937/integrated Del: useless -- https://master.php.net/note/delete/120937/useless Del: bad code -- https://master.php.net/note/delete/120937/bad+code Del: spam -- https://master.php.net/note/delete/120937/spam Del: non-english -- https://master.php.net/note/delete/120937/non-english Del: in docs -- https://master.php.net/note/delete/120937/in+docs Del: other reasons-- https://master.php.net/note/delete/120937 Reject -- https://master.php.net/note/reject/120937 Search -- https://master.php.net/manage/user-notes.php
