thinkphp little brother I executed an UPDATE statement to get the number of rows affected

thinkphp I executed an UPDATE statement to get to the number of rows affected
Example:

PHP Code

  
  $book = M (' book '), $data = Array (), $data [' shengcunqi '] = time (); $book->save ($data, Array (' where ' = ' = ' Shengcunqi = ' 0000-00-00 00:00:00 ' ", ' limit ' = ' 17 ');//I want to get the number of rows affected by this statement. In other words: I want to get to how many statements I have updated altogether.

------Solution--------------------

PHP Code

$book = M (' book '), $data = Array (), $data [' shengcunqi '] = time (), $result = $book->save ($data, Array (' where ' = ') Shengcunqi = ' 0000-00-00 00:00:00 ' ", ' limit ' = ') '); Var_dump ($result); $result will return the number of rows you have affected or false
