how to remove an object reference from a php array without destroying its object

I need to remove an object from an array in php but I need the object reference to still exist, when I tried using unset() as described here it unset both the array element and the object itself, how can I remove the reference from the array without destroying the object?

my code looks like the following:

$this->array[id] = myobject;
unset($this->array[$id]);

Have you tried to keep a reference of the object before destroy array reference?

$user = new User('name','surname');
$myUserReference = $user;
$data = array('user'=> $user);

print_r($data);
unset($data['user']);
print_r($data);

This should print an array containing $user object and an empty array then. You should have a reference to $user object in $myUserReference var

This code works just fine for me:

$my_var = 1;
$my_array = array();
$id = 0;

$my_array[$id] = $my_var;
print_r($my_array);
print_r($my_var);

unset($my_array[$id]);
print_r($my_array);
print_r($my_var);

At the end of it all, I have cleared the $id (0) index from $my_array, by $my_var is still equal to 1.

You need another reference for this object. Look at this code:

<?php
$var = 1;

$data = array("id" => &$var);
unset($data['id']);

var_dump($var);
var_dump($data);

It prints:

int(1)
array(0) {
}

Just keep another reference to this object somewhere else.
