suggested improvement for bug21131.phpt

Hi, while looking at a reported bug, I found that ext/standard/tests/file/bug21131.phpt almost tested the reported case. The report was that fopen("","a+") was not going to the end. When looking at the test case, I could see that the test was using "a+", but as it was not writing anything at that point, it seemed to not test my case..... With the addition of one line and a slight change to the output, I found that I had a good test case and that I could not reproduce the problem :-). Perhaps you might like to add my changes to the test (or let me know and I will make the change). As changed: --TEST-- Bug #21131: fopen($filename, "a+") has broken position --FILE-- <?php # vim600:syn=php: $filename = tempnam("/tmp", "phpt"); $fp = fopen($filename, "w") or die("can't open $filename for append"); fwrite($fp, "foobar"); fclose($fp); $fp = fopen($filename, "a+");

fwrite($fp, "FOOBAR");                        /* changed line */

rewind($fp); fpassthru($fp); fclose($fp); unlink($filename); ?> --EXPECT-- foobarFOOBAR
