Description
Procedural style:
mixed
mysqli_num_rows ( mysqli result )
Object oriented style (property):
class
mysqli {
mixed num_rows
}
Returns the number of rows in the result set.
The use of mysqli_num_rows() depends on whether you use
buffered or unbuffered result sets.
In case you use unbuffered resultsets mysqli_num_rows()
will not correct the correct number of rows until all the rows in the result
have been retrieved.
