Req #52281 [NEW]: New Unref function - breaks reference between variables.

From: Operating system: PHP version: Irrelevant Package: Unknown/Other Function Bug Type: Feature/Change Request Bug description:New Unref function - breaks reference between variables. Description: ------------ An addition to PHP that would be nice is a way to break a reference between two variables, without destroying them. Currently, the only way I found to break a reference is to use unset($var), however this causes the variable to be destroyed which causes can cause undesirable side-effects on classes. Suggested function: unref($var) - Removes references from $var. The function would give $var whatever value it currently has via it's reference, and then removes the reference.
