Actually I think it's pretty clear Previous Comments: ------------------------------------------------------------------------ [2002-06-09 14:53:11] pgl@instinct.org $array[] = 1 is not the same as $array[$somenullvalue] = 1. This is not intuitive and undocumented as far as I can tell. Example: --8<-- [armadillo:pgl]:~/public_html/test $ cat test.php <? #!/usr/local/bin/php -q $array[] = 1; $array[] = 2; print_r($array); unset($array); $null = ''; $array[$null] = 3; $array[$null] = 4; print_r($array); ?> --8<-- Prints: --8<-- Array ( [0] => 1 [1] => 2 ) Array ( [] => 4 ) --8<-- I would say this is a documentation problem, but I can't see how this behaviour could be useful. regards, Peter Lowe. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=17668&edit=1
