如何在 MySQL 查詢中有效地使用 PHP ID 陣列？

$ids  = array(2, 4, 6, 8);

// Prepare the SQL statement with a single parameter placeholder
$sql  = "UPDATE MyTable SET LastUpdated = GETDATE() WHERE id = ?";
$stmt = $mysqli->prepare($sql);

// Bind a different value to the placeholder for each execution
for ($i = 0; $i < count($ids); $i++) {
    $stmt->bind_param("i", $ids[$i]);
    $stmt->execute();
    echo "Updated record ID: $id\n";
}

$ids    = array(2, 4, 6, 8);

// Prepare the SQL statement with multiple parameter placeholders
$params = implode(",", array_fill(0, count($ids), "?"));
$sql    = "UPDATE MyTable SET LastUpdated = GETDATE() WHERE id IN ($params)";
$stmt   = $mysqli->prepare($sql);

// Bind all parameter values at once using dynamic function call
$types = str_repeat("i", count($ids));
$args = array_merge(array($types), $ids);
call_user_func_array(array($stmt, 'bind_param'), ref($args));

// Execute the query for all input values in one step
$stmt->execute();
