To be honest, I am in touch with PHP because of the need for big jobs. THinkPHP is just getting started. it takes a lot of time and I can only learn what I want, so there are basically no basic skills.

ThinkPHP:

$ User = M ("User"); // instantiate the User object
// Assign values to the attributes of the data object to be modified
$ Data ['name'] = 'thinkphp ';
$ Data ['email '] = 'thinkphp @ gmail.com ';
$ User-> where ('Id = 5')-> save ($ data); // save the modified data according to the conditions.
