OK, so here's the solution I came up with. A little harder to read here than
in an editor, but it's as clean and tight as I could make it. I use it as
the body of a function that returns $displayThese to a script uses the
newsID values to display those news items that have not expired AND the user
has not marked as read. Your mileage may vary ;^)
$sql_getNews = "SELECT newsID FROM news WHERE CURDATE()
BETWEEN startDate AND endDate";
$result_getNews = mysql_query($sql_getNews)
or die(mysql_error());
$sql_getReadItems = "SELECT newsID FROM newsReadBy WHERE
userID='".$creatorID."'";
$result_getReadItems = mysql_query($sql_getReadItems)
or die(mysql_error());
$readList = mysql_fetch_array($result_getReadItems);//turn
Resource ID into an assoc. array
//check to see if a valid newsID ($newsList["newsID"]) has
already been read (appears in $readList)
while($newsList = mysql_fetch_array($result_getNews)){
if($readList){
if (!in_array($newsList["newsID"],
$readList)){
$displayThese[] =
$newsList["newsID"];
}
}
else{
$displayThese[] = $newsList["newsID"];
}
}
