Bug description: array_merge allowing "false" as argument
Description:
------------
Code:
---------------------------------------
$array1=false;
$array2=array("test"=>"1","testing"=>"2");
$last_array=array_merge($array1,$array2);
echo "<pre>"; print_r($last_array); echo "</pre>";
---------------------------------------
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:
---------------
<?php
$array1=false;
$array2=array("test"=>"1","testing"=>"2");
$last_array=array_merge($array1,$array2);
echo "<pre>"; print_r($last_array); echo "</pre>";
?>
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
)
