如何在SQL查询中检查数组？

Question

So I need to check an array in my query:

$query = "SELECT * FROM post WHERE ".$select." LIKE '%".$search."%'  AND  ID NOT IN '" .$Lastvar."'";

$Lastvar is my array. I have no idea where to go from here an any help would be appreciated.

EDIT: Here's my full query:

$Lastvar = array();
mysql_select_db('submisions', $dbconn);
$query = "SELECT * FROM post WHERE ".$select." LIKE '%".$search."%' AND ID NOT IN (" . join(", ", $Lastvar) . ")";

$result = mysql_query($query);
$num_rows = mysql_num_rows($result);
if ($num_rows == 0) {
    echo 'No results were found';
    exit;
}

Answer 1

If the ID is of integer type:

$query = "SELECT * FROM post WHERE ".$select." LIKE '%".$search."%'  
AND ID NOT IN (" . join(", ", $Lastvar) . ")";

Answer 2

像这样做：

$query = "SELECT * FROM post WHERE ".$select." LIKE '%".$search."%'  AND  ID NOT IN ('" .join("', '", $Lastvar).")";
