是否可以通过mysql拉出表的创建语法?

I'm looking to pull a table's create syntax via mysql and php. Is it possible?

I need it for a file that creates table_x automatically every 10 days. Since I update the site constantly and create new fields I'd like the file to be dynamic and use the previous table (instead of me updating it manually each time).

Yes you can - use

SHOW CREATE TABLE tablename;

Actually if you want to 'reset' your database I would use TRUNCATE instead

TRUNCATE TABLE tablename
SHOW CREATE TABLE table_x;

...will output one record with the CREATE syntax. Is that what you're looking for?
