Sort parameter values

Hello,

I have an mysql query which need to be filtered by the values from a parameter that looks like this: <url>?featuresId=18, 2, 50

The issue is that i need the values to be ordered ascending in order to display the correct results. The received values should be like (2,18,50)

My sql query looks something like this:
get_features_query = "select * from features where feature_name like '%|" . str_replace(",", "|%|", $HTTP_GET_VARS['featuresId']) . "|%'"

Thanks

try:
$temp=explode(',', $HTTP_GET_VARS['featuresId']);
foreach($temp as $index=>$value)
{
	if(is_int($value))
	{
		$temp[$index]=(int)$value;
	}
	else
	{
		unset($temp[$index]);
	}
}
asort($temp);
$get_features_query = "select * from features where feature_name like '%|" . implode("|%|", $temp) . "|%'";

Hi,

your array returns empty values. i don't know why. I've tried to echo it and i get no values.

$temp=explode(',', $HTTP_GET_VARS['featuresId']);
foreach($temp as $index=>$value)
{
      if(is_int($value))
      {
            $temp[$index]=(int)$value;
      }
      else
      {
            unset($temp[$index]);
      }
}
asort($temp);

echo '%|"' . implode("|%|", $temp) . '"|%';
