Objective c:
NSString *jsonString;
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:mutablearray
options:NSJSONWritingPrettyPrinted
error:&error];
if (!jsonData) {
NSLog(@"Got an error: %@", error);
} else {
jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
}
eg:
NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:
// Object and key pairs
firstName, @"fname",
lastName, @"lname",
phoneNumStr, @"phone_no",
emailStr, @"email_id",
nil];
[allObjectArray addObject:dict];
php:
$json_str = $_POST['jsonstring'];
$contact_details = json_decode($json_str);
foreach($contact_details as $key => $value)
{
$fname = $value->fname;
$lname = $value->lname;
$email = $value->email_id;
$phone = $value->phone_no;
//insert or update query
}
