Using array_push with closures overwriting previous element - php

Question

I have a strange problem. I am writing a callback-like system where some code calls a function in a class which adds the function to an array and then later on executes it. Here is my code:
class BaconClass {
private $array;
public function __construct() {
$this->array = array();
}
public function AddBacon($function) {
array_push($this->array, $function);
}
/* ... */
public function GetBacon() {
foreach($this->array as $function) {
echo $function();
}
}
}
Then I have some other code like this:
$bacon = new BaconClass();
$bacon->AddBacon(function() {
echo "Om nom nom";
});
/* And somewhere else I might have */
$bacon->AddBacon(function() {
echo "I like bacon";
});
/* And then after all of this I have */
$bacon->GetBacon();
This code will only print:
I like bacon
I have made sure that the array being passed to the AddBacon function is actually working, but whenever I use var_dump to see what is inside the array after I add an element to it, it always shows one object, which is always the latest one added.
Why is the code overwriting the previous element? If there is a better way to implement this code, I am open to suggestions.
What I have tried
I have tried using $this->array[] = $function, and I have also tried using $this->array[count($this->array)] = $function. Neither are working.

Just tested the provided code in php console, got this output;
class BaconClass {
private $array;
public function __construct() {
$this->array = array();
}
public function AddBacon($function) {
array_push($this->array, $function);
}
/* ... */
public function GetBacon() {
foreach($this->array as $function) {
echo $function();
}
}
}
$bc = new BaconClass();
$bc->AddBacon(function() {echo 'something'; });
$bc->AddBacon(function() {echo 'something else'; });
$bc->GetBacon();
// outputs: somethingsomething else
Seems to be working fine to me
