Question : looping array makes array not empty, even though reset applied at start of loop

hello~

hope just missing something simple here
for some reason when i am looping a function, the array does not "reset/empty" even though have specified to do so at start of each loop, with both unset and array()

in example code given, the last domain in array is expecting to yield "NO MX"
eg: if only run the cut portion per comments, it does yield "NO MX" BUT when running as a whole, it seems to carry over the array from previous domain and yields "YES MX"

not sure why
thanks~

<?php
$array = array("google.com", "yahoo.com", "ihavenomx.com");

for($c=0; $c < 3; $c++)
{
$domain = "$array[$c]";
unset($mxrecords);
$mxrecords = array();

//start cut from here without loop from above
getmxrr($domain, $mx_host, $mx_weight);

	for($i=0; $i < count($mx_host); $i++)
	{
	$mxrecords[$mx_host[$i]] = $mx_weight[$i];
	}
		if (empty($mxrecords))
		{
		echo "NO MX<br>";
		}
			else
			{
			echo "YES MX<br>";
			}
//end cut
}
?>
