pdo無效的令牌數量

Question

$statement = $connection->prepare("INSERT INTO test(emailAddress, password) VALUES(:emailAddress, :password)"); 
$data = array("emailAddress" => "test1", "password" => "test", "abc" => 123); 

if($statement->execute($data)) { 
    echo $connection->lastInsertId(); 
} else { 
    echo "error"; 
} 

我知道令牌的數量超過了所需的數量，但有時我的數組可能會有更多，我需要它們。

Invalid parameter number: number of bound variables does not match number of tokens' 

PDO可以忽略額外的參數嗎？

不，PDO要求您具有與準備的查詢中的參數數量相同的值數量。

學習使用array_intersect_key()：

$keys = array("emailAddress", "password"); 
$data = array("emailAddress" => "test1", "password" => "test", "abc" => 123); 

if($statement->execute(array_intersect_key($data, array_flip($keys)))) { 
    . . .
