使用PDO将整数从64位转换为32位

Question

I am storing 64bit Facebook ids in our mysql database. When I view the database table the values are 32bit. I am using Laravel, with the PDO connection. The values, if dumped out, are correct in the bindings. Once executed they are different in the DB. I have tried changing database from MariaDB to MySQL to see if it was the database causing it. Everything points to it being PDO.

This does not happen on my local development machine which is using the exact same version of PHP 7.0.15 . I get no errors on either development or local.

MySQL and PHP are 64bit versions. I have not been able to find anything that helps me resolve the issue.

I found this bug report from 2013 that clearly illustrates my issue but seems to have been resolved.

In Laravel's Connection class the bindValues method is checking the data type like so.

public function bindValues($statement, $bindings)
{
    foreach ($bindings as $key => $value) {
        dump($value); // Value is correct at this point.
        $statement->bindValue(
            is_string($key) ? $key : $key + 1, $value,
            is_int($value) ? PDO::PARAM_INT : PDO::PARAM_STR
        );
    }
}

I have also tried setting the third param to just be PDO::PARAM_STR but that didn't change the behavior.

The server is CentOS Linux 7.3.1611 , MySQL is 5.7.17 , PHP 7.0.15

PDO and MySql Extensions

php70w-pdo.x86_64                   7.0.15-1.w7 @webtatic
php70w-mysql.x86_64                 7.0.15-1.w7 @webtatic

The table is InnoDB with UTF-8 Unicode encoding and the collation is utf8_unicode_ci

The sql connection is:

'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => true,
'modes' => ['STRICT_TRANS_TABLES','NO_ZERO_IN_DATE','NO_ZERO_DATE','ERROR_FOR_DIVISION_BY_ZERO','NO_AUTO_CREATE_USER','NO_ENGINE_SUBSTITUTION'],
'engine' => null,

What things can I try to resolve my issue?

Answer 1

I found the solution. Our server was using the regular php70-mysql drivers and not the native drivers php70-mysqlnd . Once we updated that the integers were preserved.
