This is at least rather confusing, since one expects __toString() to return a string. See also <http://php.net/manual/en/splfileobject.tostring.php#123238>. Test script: --------------- <?php $file = new SplTempFileObject; $file->fputcsv(['foo', 'bar', 'baz']); $file->rewind(); $file->setFlags(SplFileObject::READ_CSV); echo gettype($file->__toString()); ?> Expected result: ---------------- string Actual result: -------------- array ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77024&edit=1
