使用WHERE子句接受数组进行SQL查询

Question

我有一个包含六个元素（$categories = array('dinner','casual','wedding')）的数组，我想创建一个如下所示的SQL查询：

SELECT * FROM produts WHERE id = /* values of array $categories... eg. (dinner || casual || wedding) */

Answer 1

试试这个：

$conditions = '';

foreach($categories as $cat) {
    $conditions[] = " id = '".$cat."'";
}

$sql = 'SELECT * FROM produts WHERE '.implode(" OR ", $conditions);

Answer 2

您必须使用IN而不是WHERE。
