如果你想坚持顺序无关紧要的语法,你必须做一些额外的工作,但我会告诉你一种更简单的方法来绑定参数::param
// store all your parameters in one array
$params = array(
':status' => 'declined'
);
// then, using your arbitrary array of id's ...
$array_of_ids = array(5, 6, 12, 14);
// ... we're going to build an array of corresponding parameter names
$id_params = array();
foreach ($array_of_ids as $i => $id) {
// generate a unique name for this parameter
$name = ":id_$i"; // ":id_0", ":id_1", etc.
// set the value
$params[$name] = $id;
// and keep track of the name
$id_params[] = $name;
}
// next prepare the parameter names for placement in the query string
$id_params = implode(',', $id_params); // ":id_0,:id_1,..."
$sql = "select * from user where id in ($id_params) and status = :status";
在这种情况下,我们最终得到:"select * from user where id in (:id_0,:id_1,:id_2,:id_3) and status = :status"
// now prepare your statement like before...
$stmt = $em->getConnection()->prepare($sql);
// ...bind all the params in one go...
$stmt->execute($params);
// ...and get your results!
$result = $stmt->fetchAll();
此方法还将适用于字符串数组。
