php - How to use PHP Array in MySQL Select statement with IN?

Question

I have an array and I wrote this code which does not work. Could someone help me with this query? Thanks a lot!

 $sql = "SELECT * FROM `product` WHERE `product`.`Productcode` IN (".$array.") ";
         $result=mysql_query($sql);
         if(!$result)die('not exist');

Answer 1

the array should be a string

$string = implode("','", $array);
$sql = "SELECT * FROM `product` WHERE `product`.`Productcode` IN ('".$string."') ";

quotes not needed if the productcode is an integer

Answer 2

如果您的阵列不是多维的，请尝试此操作

$sql = "SELECT * FROM `product` WHERE `product`.`Productcode` IN ('".implode("',", $array)."') ";

Answer 3

You need to implode() the array to a string (presuming your $array is actually an array):

$sql = "SELECT * FROM `product` WHERE `product`.`Productcode` IN ('" . implode("', '", $array) . "')";

Answer 4

You need to implode the array to a comma separated list before it can be used IN()

IN(".implode(',',$array).")
