2. The value in the merged array is (bool) false

array_merge_recursive() shows the same behavior
array_intersect(), however, doesn't and gives a correct warning message

Description:

Code:
---
$array1=false; 
$array2=array("test"=>"1","testing"=>"2");
$last_array=array_merge($array1,$array2); 
echo ""; print_r($last_array); echo "";
---

Result:
---
Array
(
[0] => 
[test] => 1
[testing] => 2
)
---

Please note that not only does array_merge allow the "false" to be
passed in, but when it is, a mysterious [0] appears in the results
(null array value?)

Reproduce code:
---
"1","testing"=>"2");
$last_array=array_merge($array1,$array2);
echo ""; print_r($last_array); echo "";
?>

Expected result:

Either an "invalid argument" for the "false" being passed in, or no
extra Null array value appended to the resulting array.

Actual result:
--
Array
(
[0] => 
[test] => 1
[testing] => 2
)
