I don't think i agree with the with the way you are capturing the error ... you can try
$nodes = array(
"http://google.com",
"http://iamdooooooooooown.com",
"https://gokillyourself.com"
);
echo "<pre>";
print_r(multiplePost($nodes));
Output
Array
(
[google.com] => #HTTP-OK 48.52 kb returned
[iamdooooooooooown.com] => #HTTP-ERROR 0 for : http://iamdooooooooooown.com
[gokillyourself.com] => #HTTP-ERROR 0 for : https://gokillyourself.com
)
