Edit report at https://bugs.php.net/bug.php?id=69275&edit=1 ID: 69275 Comment by: danack@php.net Reported by: stephen dot reay at me dot com Summary: SplFileObject constructor cannot be overridden Status: Assigned Type: Bug Package: *General Issues Operating System: OS X, Linux PHP Version: 5.6.7 Assigned To: danack Block user comment: N Private report: N New Comment: I'm looking at it yes. Whether I'm able to fix it, is a question yet to be determined. Previous Comments: ------------------------------------------------------------------------ [2015-03-24 05:44:45] laruence@php.net @danack are you able to make a patch? thanks ------------------------------------------------------------------------ [2015-03-22 19:23:00] danack@php.net The cause is pretty clear. When the class is the standard SplFileObject the parameters passed to openFile are read and passed to the file open call. http://lxr.php.net/xref/PHP_5_6/ext/spl/spl_directory.c#537 When the class isn't that class, the params aren't parsed and instead the mode is set to 'r' only: http://lxr.php.net/xref/PHP_5_6/ext/spl/spl_directory.c#524 Which obviously causes the file opening to fail, as the file doesn't exist. ------------------------------------------------------------------------ [2015-03-22 07:41:53] stephen dot reay at me dot com Description: ------------ A class that extends SplFileObject, specifies its own constructor and is registered with SplFileInfo::setFileClass() will only be instantiated with the first argument passed to SplFileInfo::openFile(). Test script: --------------- <?php class FileObject extends \SplFileObject { public function __construct($file_name, $open_mode = 'r', $use_include_path = false, $context = null) { if (is_resource($context)) { parent::__construct($file_name, $open_mode, $use_include_path, $context); } else { parent::__construct($file_name, $open_mode, $use_include_path); } } } $file = new \SplFileInfo(__DIR__ . DIRECTORY_SEPARATOR . 'foo'); $file->setFileClass('FileObject'); $file->openFile('w+'); Expected result: ---------------- File is created Actual result: -------------- Fatal error: Uncaught exception 'RuntimeException' with message 'SplFileObject::__construct(/Users/stephen/Projects/Koalephant/Bamboo/tests/foo): failed to open stream: No such file or directory' in /Users/stephen/Projects/Koalephant/Bamboo/tests/SplFileInfoTest.php:10 Stack trace: #0 /Users/stephen/Projects/Koalephant/Bamboo/tests/SplFileInfoTest.php(10): SplFileObject->__construct('/Users/stephen/...', 'r', false) #1 [internal function]: FileObject->__construct('/Users/stephen/...', 'r') #2 /Users/stephen/Projects/Koalephant/Bamboo/tests/SplFileInfoTest.php(19): SplFileInfo->openFile('w+') #3 {main} thrown in /Users/stephen/Projects/Koalephant/Bamboo/tests/SplFileInfoTest.php on line 10 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69275&edit=1
