凡在從PHP MySQL的陣列多列

Question

無法找到如何在克勞斯在不止一個欄 我有例子做這個查詢：

$post = json_decode($HTTP_RAW_POST_DATA); 
$phoneNumbers = implode(",", $post->phones); 
$emails = implode(",", $post->emails); 

$sql = "SELECT phone_number,email,id FROM users WHERE phone_number,email IN (($phoneNumbers),($emails))"; 
$result = mysql_query($sql); 

Paramenters從反應後得到的，我需要將其與邏輯OR進行比較。 這個例子不適合我，結果不算什麼。 我該怎麼做。 THX

Answer 1

$post = json_decode($HTTP_RAW_POST_DATA); 
$phoneNumbers = $post->phones; 
$emails = $post->emails; 

$ors = []; 
foreach ($phoneNumbers as $i => $number) { 
    $ors[] = "(phone_number = :phoneNumber{$i})"; 
    $params[":phoneNumber{$i}"] = $number; 
} 

foreach ($emails as $i => $email) { 
    $ors[] = "(email = :email{$i})"; 
    $params[":email{$i}"] = $email; 
} 

$query = $pdo->prepare("SELECT phone_number, email, id FROM users WHERE ".implode(' OR ', $ors)); 
print_r($query); 
$query->execute($params); 

Answer 2

連接兩個WHERE IN與AND：

SELECT phone_number, email, id FROM users WHERE phone_number IN ({$phoneNumbers}) AND email IN ($emails)

如果您需要匹配電話號碼和電子郵件，不是生成查詢：

$ors = []; 

foreach ($phoneNumbers as $i => $number) { 
    $ors[] = "(phone_number = :phoneNumber{$i} AND email = :email{$i})"; 
    $params[":phoneNumber{$i}"] = $number; 
    $params[":email{$i}"] = $emails[$i]; 
} 

$query = $pdo->prepare("SELECT phone_number, email, id FROM users WHERE ".implode(' OR ', $ors)); 
$query->execute($params); 

Answer 3

SELECT 
    phone_number, 
    email, 
    id 
FROM users 
WHERE phone_number IN ($phoneNumbers) 
    OR email IN ($emails)
