Previous Comments: ------------------------------------------------------------------------ [2008-04-26 09:08:49] dev_oskar at hotmail dot com Description: ------------ RecursiveDirectoryIterator::getChildren uses a hard coded reference to itself in the function getChildren, so it can't be extended. Note: It's not possible to completely overwrite getChildren without a lose of subPath handling. In spl_directory.c: SPL_METHOD(RecursiveDirectoryIterator, getChildren) ... spl_instantiate_arg_ex1(spl_ce_RecursiveDirectoryIterator, &return_value, 0, &zpath TSRMLS_CC); ... This should be changed to something like the RecursiveFilterIterator getChildren uses: spl_instantiate_arg_ex1(Z_OBJCE_P(getThis() ... Reproduce code: --------------- class RecursiveDirectoryIteratorTest extends RecursiveDirectoryIterator { public function test() { echo "test"; } } $di = new RecursiveIteratorIterator(new RecursiveDirectoryIteratorTest ("/somepathwithsubfolders"), RecursiveIteratorIterator::SELF_FIRST); foreach ($di as $key => $value) { echo $key, " - ",$value, $di->test(),"<br>"; } Expected result: ---------------- echoing "test" for each item. Actual result: -------------- Call to undefined method RecursiveDirectoryIterator::test() as soon getChildren creates a new object for a subfolder. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44838&edit=1
