PDO support for multiple queries (PDO_MYSQL, PDO_MYSQLND)

Question

I do know that PDO does not support multiple queries getting executed in one statement. I\'ve been Googleing and found few posts talking about PDO_MYSQL and PDO_MYSQLND.

Answer 1

A quick-and-dirty approach:

function exec_sql_from_file($path, PDO $pdo) {
    if (! preg_match_all("/('(\\\\.|.)*?'|[^;])+/s", file_get_contents($path), $m))
        return;

    foreach ($m[0] as $sql) {
        if (strlen(trim($sql)))
            $pdo->exec($sql);
    }
}

Splits at reasonable SQL statement end points. There is no error checking, no injection protection. Understand your use before using it. Personally, I use it for seeding raw migration files for integration testing.
