getResult , getResultArray , getRow, getRowArray in codeigniter - 4
Deepak Tailor - Oct 17 2020
There are several ways in Codeigniter 4 to generate query results. Such as for object format getResult(), for array getResultArray(),for single row in object getRows(),for single row in array getRowArray() functions etc.
getResult() function
The getResult() function returns data to us in the object format.
$this->seller // database connection set in constructor
public function get_all_data()
{
$query = $this->seller->query('SELECT * FROM users');
echo "<pre>";
print_r($query->getResult());
}getResultArray() function
This method returns the query result as a pure array, or an empty array when no result is produced.
public function get_all_data()
{
$query = $this->seller->query('SELECT * FROM users');
echo "<pre>";
print_r($query->getResult('array')); // return result in array
}
public function get_all_data()
{
$query = $this->seller->query('SELECT * FROM users');
echo "<pre>";
print_r($query->getResultArray('array'));
}getRow() function
If we have more than one rows in our query and we need only one row, then we use this getRow function.
public function get_all_data()
{
$query = $this->seller->query('SELECT * FROM users');
echo "<pre>";
print_r($query->getRow());
}getRowArray() function
If our query has more than one rows and we want the same single row array format, then we use this getRowArray function.
public function get_all_data()
{
$query = $this->seller->query('SELECT * FROM users');
echo "<pre>";
print_r($query->getRowArray());
}getFirstRow() function
If first row is needed from our query, then we use this getFirstRow function.
public function get_all_data()
{
$query = $this->seller->query('SELECT * FROM users');
echo "<pre>";
print_r($query->getFirstRow());
}getLastRow() function
If we want the last row from our query, then we use this getLastRow function.
public function get_all_data()
{
$query = $this->seller->query('SELECT * FROM users');
echo "<pre>";
print_r($query->getLastRow());
}getFieldCount() and getFieldNames() function
If we want to count the fields in a table or fetch the name of the fields, we use the getFieldCount() and getFieldNames() functions.
public function get_all_data()
{
$query = $this->seller->query('SELECT * FROM users');
echo "<pre>";
print_r($query->getFieldCount());
echo "<br/>";
print_r($query->getFieldNames());
