This is how it works in 4.3.0, 4.3.6, 4.3.11, 5.0.x.
No bug here.

Please refer to the following docs page:

< http://us3.php.net/manual/en/function.array-merge.php >

If you want to completely preserve the arrays and just want to append them to each other, use the + operator:
<?php
$array1 = array();
$array2 = array(1 => "data");
$result = $array1 + $array2;
?> 

i know that array_merge is the proper function to use in my previous test case, for the output. but, regardless, if the key association is being maintaed in my previous test case, the output should really be [0] => d [1]=>e [2]=>c


please revisit, or redoc on the manpage.
