Description:
------------
My request is to have implode not blow up when not given an array.  This could be done by setting a standard for the variable order

implode(glue, pieces)

check pieces for is_array()...if so, then do your thing, if not then return pieces instead of an error.

Reproduce code:
---------------
$arr="blah";

$new_list = implode ("|", $arr);

echo $new_list;

Expected result:
----------------
blah

Actual result:
--------------
error:....
