Is there a way to resume or continue with the next $value of the foreach loop if the query result is null or empty? If so, how please? The way this is supposed to work is $_POST['select'] contains multiple zip codes. As $value is iterated, vacpct is selected from the database to be placed in an array. The problem is, if a zip code has 0 (zero) for vacpct, the result of the query is null or empty (not sure which) as only zip codes that have vacpct that are greater than 0 (zero) are to be selected. When this happens, the action stops, and the next $value(s) or zip codes are not itereated. I need a way to continue with the next $value when this happens. Thanks in advance.

PHP Code:

foreach ($_POST['selectzip'] as $value)  {

if ($value != " ") {

$resultsvacpct = "SELECT vacpct FROM wamuexp where  vacpct > 0 &&  zip LIKE '$value%'  ORDER BY vacpct";
$sql_resultsvacpct = mysql_query($resultsvacpct,$dbc); 

$i=0; 
while ($row = mysql_fetch_array($sql_resultsvacpct))
{ 
// load array with data from table 
$vacpctarr[] = $row[vacpct]; 

//echo "$vacpctarr[$i]<br>"; 

$i = $i + 1; 

} 
}
} 


Just use continue to iterate the next loop. So your check line at the top of the loop could be:

if ((int)$value <= 0) continue;
