thinkphp adding Data Add () method

The Thinkphpz built-in Add () method is used to add data to a database table, equivalent to the INSERT into behavior in SQL
Adding the Data add method is the implementation of create in curd (Create,update,read,delete/Create, modify, read, delete), thinkphp supports writing data to the data table in a normal array and object-oriented manner.
Insert to write data to the data table in a normal array
$insert [' user_id ']= $my [' user_id '];
$insert [' Content_body ']= $content;
$insert [' Posttime ']=time ();
$insert [' Replyid ']= $sid;
$insert [' type ']= $type;
$insertid = $this->add ($insert);
Because the file is in contentModel.class.php, $this<=>d ("Content")
Add () method if the data record is added successfully, the new data record primary key is returned, which can be directly obtained

/*********** writes data to a data table as an object and does not need to pass parameters when the Add method is called to write data *************/
