php - 如何在 sql 查询中检查数组？

Question

所以我需要在我的查询中检查一个数组：

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

$Lastvar是我的阵列。我不知道从这里去哪里，任何帮助将不胜感激。

编辑：这是我的完整查询：

$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

Do it like this:

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