Previous Comments: ------------------------------------------------------------------------ [2002-03-01 20:10:26] [EMAIL PROTECTED] Making this a documentation problem. Static variables just can't hold references of any kind. For objects it's avoidable with ZE2 because of the new object model. ------------------------------------------------------------------------ [2001-07-29 05:14:19] [EMAIL PROTECTED] Another unfortunate bug with references appears to be that statics holding references inside methods are actually transient, and a reference will be lost. For example, calling the following code several times will initialise $db and return every time with a new instance. function &getInstance() { static $db; if (!isset($db)) { $db =& new FS_DB(); } return $db; } whereas the following will give true singeton behaviour and initialise just once, as expected. function &getInstance() { static $db; if (!isset($db)) { $db = new FS_DB(); } return $db; } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=12454&edit=1
