Grab one field for all entries

[k89mmmk]

Is there a way to get all the values of one field into an array in mysql? I have a unique number in a field called 'time'. I want to grab all times to make sure that a new time is not already entered. Any suggestions??

Thanks.

$sql = mysql_query("SELECT time FROM table");
$results=array();
$i=0;
while($r=mysql_fetch_array($sql)) {
   $results[$i] = $r['time'];
   $i++;
}
