Unpatched PHP-4.3.6 would repeat the last two values in additional two array slots. Forms submitted via get didn't exhibit this behavior. Scalars passed via post also did not exhibit this behavior. After I patched the C code as above, I got three and only three strings back in $_POST["a], which is what I'd expect. Actual result: -------------- Array ( [0] => val1 [1] => val2 [2] => val3 [3] => val2 [4] => val3) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28439&edit=1
