There are some (what I would call) "engineering" issues with your function
but it looks like it should work. Maybe your problem lies in the array?
// Cleaned up function..
function array_is_numeric($array)
{
$result=true;
for($i=0; $i<sizeof($array); $i++)
{
if(!is_numeric($array[$i]))
$result=false;
}
return $result;
}
