I just wanted to share a change I made on the result_array db function. It will let you specify a column to use as a key in the array that it returns:
Code:
$this->db->query($sql)->result_array('id');
In that example it would use the id column as the array key, which I think makes it easier to work with in some situations.
Here's the modified function from DB_result.php
Code:
function result_array($key = NULL)
{
if (count($this->result_array) > 0)
{
return $this->result_array;
}
// In the event that query caching is on the result_id variable
// will return FALSE since there isn't a valid SQL resource so
// we'll simply return an empty array.
if ($this->result_id === FALSE OR $this->num_rows() == 0)
{
return array();
}
$this->_data_seek(0);
while ($row = $this->_fetch_assoc())
{
if ( ! is_null($key) )
$this->result_array[$row[$key]] = $row;
else
$this->result_array[] = $row;
}
return $this->result_array;
}
