First you need to check whether the user or data is exits or not. then you can perform the update and insert operation.

$this->db->where('user_id',$id);
$q = $this->db->get('profile');
if ( $q->num_rows() > 0 )
{
$this->db->where('user_id',$id);
$this->db->update('profile',$data);
} else {
$this->db->set('user_id', $id);
$this->db->insert('profile',$data);
}

$this->db->where('user_id',$id);

$q = $this->db->get('profile');

if ( $q->num_rows() > 0 )

{

$this->db->where('user_id',$id);

$this->db->update('profile',$data);

} else {

$this->db->set('user_id', $id);

$this->db->insert('profile',$data);

}

Push notification Android Php

Hey, Today we learn how to send push notification for android in php. First create a class with following code

&lt;?php
class Pusher{
const GOOGLE_GCM_URL = 'https://android.googleapis.com/gcm/send';
private $apiKey;
private $proxy;
private $output;
public function __construct($apiKey, $proxy = null)
{
$this-&gt;apiKey = 'your_key';
$this-&gt;proxy  = $proxy;
}
/**

* @param string $data
* @throws Exception
*/
public function notify($regIds, $data)
{
//        pr($data);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, self::GOOGLE_GCM_URL);
if (!is_null($this-&gt;proxy)) {
curl_setopt($ch, CURLOPT_PROXY, $this-&gt;proxy);
}
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $this-&gt;getHeaders());
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $this-&gt;getPostFields($regIds, $data));
$result = curl_exec($ch);
if ($result === false) {
throw new Exception(curl_error($ch));
}
curl_close($ch);
//        pr($result); die;
$this-&gt;output = $result;
return $result;
}
/**
* @return array
*/
public function getOutputAsArray()
{
return json_decode($this-&gt;output, true);
}
/**
* @return object
*/
public function getOutputAsObject()
{
return json_decode($this-&gt;output);
}
private function getHeaders(){
return [
'Authorization: key=' . $this-&gt;apiKey,
'Content-Type: application/json'
];
}
private function getPostFields($regIds, $data){
$fields = [
'registration_ids' =&gt; is_string($regIds) ? [$regIds] : $regIds,
'data'             =&gt; is_string($data) ? ['message' =&gt; $data] : $data,
];
return json_encode($fields, JSON_HEX_TAG | JSON_HEX_APOS | JSON_HEX_QUOT | JSON_HEX_AMP | JSON_UNESCAPED_UNICODE);
}
}

<?php

class Pusher{

const GOOGLE_GCM_URL = 'https://android.googleapis.com/gcm/send';

private $apiKey;

private $proxy;

private $output;

public function __construct($apiKey, $proxy = null)

{

$this->apiKey = 'your_key';

$this->proxy = $proxy;

}

/**

public function notify($regIds, $data)

{

// pr($data);

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, self::GOOGLE_GCM_URL);

if (!is_null($this->proxy)) {

curl_setopt($ch, CURLOPT_PROXY, $this->proxy);

}

curl_setopt($ch, CURLOPT_POST, true);

curl_setopt($ch, CURLOPT_HTTPHEADER, $this->getHeaders());

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($ch, CURLOPT_POSTFIELDS, $this->getPostFields($regIds, $data));

$result = curl_exec($ch);

if ($result === false) {

throw new Exception(curl_error($ch));

}

curl_close($ch);

// pr($result); die;

$this->output = $result;

return $result;

}

/**

public function getOutputAsArray()

{

return json_decode($this->output, true);

}

/**

* @return object

public function getOutputAsObject()

{

return json_decode($this->output);

}

private function getHeaders(){

return [

'Authorization: key=' . $this->apiKey,

'Content-Type: application/json'

];

}

private function getPostFields($regIds, $data){

$fields = [

'registration_ids' => is_string($regIds) ? [$regIds] : $regIds,

'data' => is_string($data) ? ['message' => $data] : $data,

];

return json_encode($fields, JSON_HEX_TAG | JSON_HEX_APOS | JSON_HEX_QUOT | JSON_HEX_AMP | JSON_UNESCAPED_UNICODE);

}

now call your notify function by creating a object of pusher class....
