当mysqli和PDO都实现真实的预处理语句时，为什么要尝试使用旧版mysql_ * API伪造预处理语句?

Why try to fake a prepared statement with the legacy mysql_* API, when both mysqli and PDO implement real prepared statements?

PDO示例:

if ($prepped = $pdo -> prepare ('UPDATE `test` SET `item1` = ?, `item2` = ?, `item3` = ?'))
{
    $res = $prepped -> execute (array (50, 55 ,60));
}
