optimizing mysql fetch code

[saqib]

Hi All,

I have to following PHP code
$result = mysql_query("SELECT user_id from user_lic where license_id=$license_id");

while($row=mysql_fetch_array($result, MYSQL_NUM)){
	$array[$i] = $row[0];
	$i++;

}

I want to optimize to fit all in one line of code.

Is that possible?

Thanks
