Question

How to solve array to string conversion error in codeigniter?

Answer 1

Explanation:

Here is my model:

public function count_diabetic(){

$query = $this->db->query("Select count(diabetic) as count_diabetic from member where diabetic is not NULL");

return $query->result_array();

}

public function count_hypertensive(){

$query = $this->db->query("Select count(hypertensive) as count_hypertensive from member where hypertensive is not NULL");

return $query->result();

}

here is my controller:

public function home(){

$this->load->model('Jsv_model');

$data = array(

'count_diabetic' => $this->Jsv_model->count_diabetic(),

'count_hypertensive' => $this->Jsv_model->count_hypertensive()

);

$this->session->set_userdata($data);

$this->load->view('home');

}

Here is my view with in php tag:

echo $this->session->userdata('count_diabetic');

But Here it shows error that array to string conversion error..

Answer 2

The error "array to string conversion" in code igniter can be solved as follows:

$arr = array( );

for each($arr as $val)

         {

                echo $val, '<br>';

         }

• This code will loop through the array.

• One more way to rectify this error is to implode the array into a comma-delimited string. This can be done in the following way:

        $arr = array( );

        echo implode(' , ', $arr) ;

• This error occurs when an array is treated like a string that cannot be done. So PHP throws this error.
