Previous Comments: ------------------------------------------------------------------------ [2005-02-14 08:13:41] pillepop2003 at yahoo dot de okay, you seem to be right. in my test unset() did not work correctly (for whatever reason...) in the beginning, what made it hard to believe that a variable is set to NULL and can't be unset. sorry for wasting your time. Keep up thw good work. ------------------------------------------------------------------------ [2005-02-13 22:49:18] [EMAIL PROTECTED] Don't mix my example with yours, mine is passing something else than an array index to the function. And this is actually (kind of) documented as undefined: http://www.php.net/manual/en/language.references.pass.php See the last paragraph, about what can be passed by reference: "Any other expression should not be passed by reference, as the result is undefined." ------------------------------------------------------------------------ [2005-02-13 20:29:19] pillepop2003 at yahoo dot de <?php function func1(&$a) { // void(); } var_dump($c); func1($c); var_dump($c); ?> should IMO output array(2) { ["one"]=> int(1) } array(2) { ["one"]=> int(1) } Why should the non-existing variable get a value (of NULL) - this is a paradoxon, isn't it? Can't it just be "not mentioned"? ------------------------------------------------------------------------ [2005-02-13 18:14:24] [EMAIL PROTECTED] What would you expect this to output: <?php function func1(&$a) { // void(); } var_dump($c); func1($c); var_dump($c); ?> IMO, this is exactly what you'd expect. The non-existing variable (or in your example, non-existing array index) gets value of NULL. I don't see what else should happen.. ------------------------------------------------------------------------ [2005-02-13 17:57:31] [EMAIL PROTECTED] This happens with both PHP_4_3 and HEAD from today. (only verified that it happens. I don't know if it's intentional or not :) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
