I have to try json_encode and json_decode but can't get json or non-object result into the controller.
In CodeIgniter controller.

Is this what you're after?
<?php
$content = <<<OUT
------WebKitFormBoundaryv6rwIfAWUgyyzeZF
Content-Disposition: form-data; name="last_name"

------WebKitFormBoundaryv6rwIfAWUgyyzeZF
Content-Disposition: form-data; name="mobile_no"
123456789
------WebKitFormBoundaryv6rwIfAWUgyyzeZF
Content-Disposition: form-data; name="country_code"
91
------WebKitFormBoundaryv6rwIfAWUgyyzeZF
Content-Disposition: form-data; name="email_id"
test.mail#gmail.com'
OUT;
$clean = str_replace("\n",'',$content);
$parts = array_filter(explode('------',$clean));
$array = array();
foreach ($parts as $row){
$parts2 = explode('name="',$row);
$parts3 = explode('"',$parts2[1]);
$array[$parts3[0]] = $parts3[1];
}
echo json_encode($array);
?>
I have a problem with your Array presentation as "first_name" would in fact be the value so I'm not sure if you've outputted your data correctly but let me know.
