note 124370 added to splfileinfo.setinfoclass

Be careful when using this method, as the functionality isn't exactly the same as instantiating the extending class directly. This can really trip you up if you're using type hints or instanceof checks. <?php class CustomFileInfo extends SplFileInfo { public function getExtension() { $ext = strtolower(parent::getExtension()); return 'jpeg' === $ext ? 'jpg' : $ext; } } $path = __DIR__ . '/foobar.jpeg'; $good = new CustomFileInfo($path); echo "<pre>"; var_dump($good instanceof SplFileInfo); var_dump($good instanceof CustomFileInfo); $bad = new SplFileInfo($path); $bad->setInfoClass('CustomFileInfo'); var_dump($bad instanceof SplFileInfo); var_dump($bad instanceof CustomFileInfo); echo "</pre>"; ?> Outputs: bool(true) bool(true) bool(true) bool(false) ---- Server IP: 208.43.231.9 Probable Submitter: 82.199.157.54 (proxied: 97.95.134.95) ---- Manual Page -- http://php.net/manual/en/splfileinfo.setinfoclass.php Edit -- https://master.php.net/note/edit/124370 Del: integrated -- https://master.php.net/note/delete/124370/integrated Del: useless -- https://master.php.net/note/delete/124370/useless Del: bad code -- https://master.php.net/note/delete/124370/bad+code Del: spam -- https://master.php.net/note/delete/124370/spam Del: non-english -- https://master.php.net/note/delete/124370/non-english Del: in docs -- https://master.php.net/note/delete/124370/in+docs Del: other reasons-- https://master.php.net/note/delete/124370 Reject -- https://master.php.net/note/reject/124370 Search -- https://master.php.net/manage/user-notes.php
