insert into multiple rows PDO

Question

i am struggling with the code to insert into multiple rows.

but ended up getting warnings

$rows = array(1,2,3,4,5,6)

$stmt = $connect->prepare("INSERT INTO t_worker_history (uid) VALUES (?)");
foreach($rows as $insert) {
    $stmt->execute($insert);
}

: PDOStatement::execute() expects parameter 1 to be array, string given in ：PDOStatement :: execute（）期望参数1为数组，字符串形式为

Answer 1

As the message says, the first parameter needs to be an array, so just put the $insert value into one:

$stmt->execute(array($insert));

See the manual . The reason the parameter needs to be an array is to allow for multiple parameters to be bound to placeholders.
