Thank you for wasting my time (again). Previous Comments: ------------------------------------------------------------------------ [2005-07-29 19:09:08] php-bug-33884 at ryandesign dot com I realize you must be very busy and that form responses let you handle bugs quicker, but I can't help but feel a little put off by them. I spent time analyzing a situation and writing it up in detail, only to have it shut down with no discussion by form responses. In particular, beginning your response with "Please do not submit the same bug more than once" makes it sound like I did so on purpose. (Your first response, which began "Thank you [...], but [...]" was better in this regard.) And especially in the case of duplicate bugs, it's essential that you let me know the other bug number, so that I can check and see whether it is truly the same bug. With the speed with which you must work through new bugs, I imagine some would get incorrectly classified; surely it's in your best interest to have us double-check for you. I'm also not sure what I think about your deleting comments from this bug. You closed my bug as bogus, pasting in a form response that it is not a bug. I wrote a detailed reply further clarifying why I believe it is. You promptly deleted your original response and my reply, to replace it with another form response saying my bug is a duplicate, without saying what of. Might not my clarification have been helpful to the person who tries to solve the bug, whether or not it is a duplicate? Since I was not able to find the bug of which this one is a duplicate, might others not have the same difficulty, and might they not possibly benefit from having more-detailed information in this bug on which they could search? ------------------------------------------------------------------------ [2005-07-29 19:08:44] php-bug-33884 at ryandesign dot com I'm sorry, I was not aware that I had submitted a duplicate. I did search beforehand and was not able to find a similar bug. Since you seem to have found one, could you please tell me its bug number so I can have a look? ------------------------------------------------------------------------ [2005-07-29 18:12:56] [EMAIL PROTECTED] Please do not submit the same bug more than once. An existing bug report already describes this very problem. Even if you feel that your issue is somewhat different, the resolution is likely to be the same. Thank you for your interest in PHP. ------------------------------------------------------------------------ [2005-07-27 15:02:41] php-bug-33884 at ryandesign dot com Description: ------------ Hi. After upgrading from PHP 4.3.11 to 4.4.0 I get the famous "Only variable references should be returned by reference" notice in one of my projects. The function in question returns by reference, but only needs to do this sometimes. Other times, it returns nothing at all, because the caller does not need a return value. In these latter cases, PHP produces the notice as of 4.4.0. This surprised me because it's perfectly fine to have a normal return-by-copy function that does not return anything. So why not a return-by-reference function? I couldn't find any documentation that if your function returns by reference, then you must always return something. In my particular case I can rewrite the function so that it always returns something, even when the caller has no use for it. I just wasn't sure if the notice in this case was intended, and if so, why. If the behavior is intended, then the documentation should reflect this. Reproduce code: --------------- error_reporting(E_ALL); function &foo_by_reference_with_return() { echo __FUNCTION__ . "<br />\n"; return $GLOBALS['bar']; } function &foo_by_reference_without_return() { echo __FUNCTION__ . "<br />\n"; } // line 11 function foo_by_copy_with_return() { echo __FUNCTION__ . "<br />\n"; return $GLOBALS['bar']; } function foo_by_copy_without_return() { echo __FUNCTION__ . "<br />\n"; } foo_by_reference_with_return(); foo_by_reference_without_return(); // causes notice in 4.4.0 foo_by_copy_with_return(); foo_by_copy_without_return(); Expected result: ---------------- foo_by_reference_with_return foo_by_reference_without_return foo_by_copy_with_return foo_by_copy_without_return Actual result: -------------- foo_by_reference_with_return foo_by_reference_without_return Notice: Only variable references should be returned by reference in references.php on line 11 foo_by_copy_with_return foo_by_copy_without_return ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33884&edit=1
