mySQL 结合 WHERE IN (?,?,?,..) 子句与 %?%

Question

如何在 stmt 查询中创建结合 WHERE IN (?,?,?,..) 子句和 %?%（通常与 LIKE 运算符一起使用）的查询？

在下面的代码中，我尝试执行类似的查询：

SELECT * FROM `items` WHERE `name` IN (%?%, %?%, %?% )

MySQL table（项目）：

================
|     name     |  
================
| google pixel | 
----------------
| iphone 9, iphone 10, iphone 11  | 
----------------
| windows phone |

PHP :

$array = array("pixel" => 1, "iphone 10" => 2);
$placeholders = array_fill(0, count($array), '?');

$keys = $values = array();
foreach($array as $key => $value) {
    $keys[] = "%".$key."%";                                             //<- here
    $values[] = !empty($value) ? $value : null;
}

$query = "SELECT * FROM `items` WHERE `name` IN (".implode(',', $placeholders).")";
$stmt = $mysqli->prepare($query);

call_user_func_array(
     array($stmt, 'bind_param'), 
     array_merge(
         array(str_repeat('s', count($keys))),
         $keys
     )
 );

 $stmt->execute();
 $result = $stmt->get_result();
 $stmt->close();

 while ($row = $result->fetch_array(MYSQLI_ASSOC)) {
     $items[$row['name']] = $row;
 }    
 $result->free();

 echo "<pre>"; print_r($items);echo"</pre>";

Nigel 的解决方案有效。我通过 :

更改查询

$query = "SELECT * FROM `items` WHERE `name` LIKE ".implode(' OR `name` LIKE ', $placeholders);

mySQL 结合 WHERE IN (?,?,?,..) 子句与 %?%

mySQL combine WHERE IN (?,?,?,..) clause with %?%

php

mysqli
