mysql — ошибка синтаксиса PHP на MyISAM & gt; InnoDB: ожидание ‘}’

При выполнении скрипта Я нашел в Интернете что кто-то создал, чтобы преобразовать MyISAM в InnoDB, он выдает синтаксическую ошибку, которую я пытался выяснить и вставил случайным образом (совсем не так глубоко в PHP-программисте.) Кто-то любезно помог бы программисту на python?

[root@server~]# php cli-mysql-to-innodb.php
PHP Parse error:  syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting '}' in /root/cli-mysql-to-innodb.php on line 44

Линии 40-53:

 40 while ($row= $results->fetch_assoc()) {
41         $sql = "SHOW TABLE STATUS WHERE Name = '{$row['Tables_in_' . $db['database']]'";
42         $thisTable = $mysqli->query($sql)->fetch_assoc();
43
44          if ($thisTable['Engine']==='MyISAM') {
45                 $sql = "alter table " . $row['Tables_in_' . $db['database']]. " ENGINE = InnoDB;";
46                 echo "Changing {$row['Tables_in_' . $db['database']]} from {$thisTable['Engine']} to InnoDB.\n";
47                 $mysqli->query($sql);}
48         } else {
49                 echo $row['Tables_in_' . $db['database']] . ' is of the Engine Type ' . $thisTable['Engine'] . ".\n";
50                 echo "Not changing to InnoDB.\n\n";
