Question

I’m using the DB class of CI framework. There’re 5 rows queried out from the first line, and the second line printed 5, but why did the statement count($query->row_array())(or count($query->row_array(),1)) returned 11(the field number of table) and only one row filled in the result, rather than 5 rows?

$query = $this->db->query($SQL_BYLABEL, array($labelId, $orderby, (int)$m, (int)$n));
    log_message('error', $query->num_rows());  // 5 rows
    log_message('error', count($query->row_array()));  // 11 

Answer 1

$query->row_array() returns the data of one record as an array. So count($query->row_array() return the number of columns of the table.

Check the manual.
