What are the potential pitfalls of using bind_param with the IN clause in PHP?

When using bind_param with the IN clause in PHP, a potential pitfall is that you cannot directly bind an array of values to the parameter. To solve this, you can dynamically create the parameter placeholders based on the number of values in the array and bind each value individually. 

// Assuming $array contains the values for the IN clause
$placeholders = implode(',', array_fill(0, count($array), '?'));
$stmt = $mysqli->prepare("SELECT * FROM table WHERE column IN ($placeholders)");

// Bind each value individually
foreach ($array as $key => $value) {
    $stmt->bind_param('s', $value);
}

$stmt->execute();
