MyISAM> InnoDB上的PHP语法错误：期望'}'

Question

执行脚本时， 我在网上发现有人创建了将MyISAM转换为InnoDB的脚本，它引发了一个语法错误，我试图找出并随机插入（根本不像PHP程序员那样深入）。有人请一个python帮助程序员？

[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

40-53行 ：

 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";
 51         }
 52 }
 53

您没有在第41行中关闭括号，

$sql = "SHOW TABLE STATUS WHERE Name = '{$row['Tables_in_' . $db['database']]'";

这样尝试

 $sql = "SHOW TABLE STATUS WHERE Name = '{$row['Tables_in_' . $db['database']]}'";
