If you want to test for an empty array after an explode this works well:
We have a variable $place which may or may not have content
$pieces = explode(" ",$place);
foreach($pieces as $key => $value) {if ((is_null($value)) or ($value == ""))
{unset($pieces[$key]);} }
$pieces = array_values($pieces); // reindex the array
print_r($pieces); // just view the array
if(empty($pieces)) {echo "array was empty";} else {echo "array contained
something";}
