I'm trying to run a php script in my app that will check the user's login variables against those in the database. The code below is how i am executing the file. I am running the script and then storing the result in arrays. a "yes" result means the user's login data is correct, a "no" result means it's incorrect.
This code works, however my issue is the time. I have set up timers and it takes 8 seconds to execute the first block even if my php file is BLANK. Everything else, even loading the next page is much faster (3 seconds tops)
//first block
NSString * post = [NSString stringWithFormat:@"userId=%@&password=%@",userId.text,password.text];
NSString * hostStr = @"http://domain.com/check_login.php?";
hostStr = [hostStr stringByAppendingString:post];
NSURL *location = [NSURL URLWithString:hostStr];
NSDictionary *dictionaryData = [[ NSDictionary alloc ] initWithContentsOfURL:location ];
//second block
NSArray *resultArray = [dictionaryData objectForKey:@"result"];
NSArray *loginidArray = [dictionaryData objectForKey:@"loginid"];
NSArray *usernameArray = [dictionaryData objectForKey:@"username"];
As well during the first block of code, about 1 out of 4 times, i get this error "SendDelegateMEssage: delegate failed to return after waiting 10 seconds. main run loop mode: _kCFURLConnectionPrivateRunLoopMode". I've been trying to look it up, but i don't know what it means in according to my code. When i get this error, the code can take 30-60 seconds to execute!!!
Any direction would be appreciated.
Thanks,
Amanda
edit to include PHP, incase it's helpful to know what's happening serverside in the code.

Solution
Here's what I went with, and it only takes 4 seconds for log in now...thanks guys.
NSHTTPURLResponse * response = nil;
NSError* error = nil;
NSString * post = [NSString stringWithFormat:@"userId=%@&password=%@",userId.text,password.text];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL: [NSURL URLWithString:@"http://domainname.com/check_login.php?"]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response
error:&error];
NSString *result = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSString *errorDesc = nil;
NSPropertyListFormat format;
NSDictionary *temp = (NSDictionary *)[NSPropertyListSerialization
propertyListFromData:returnData
mutabilityOption:NSPropertyListMutableContainersAndLeaves
format:&format
errorDescription:&errorDesc];
if (!temp) {
NSLog(@"Error reading plist: %@, format: %d", errorDesc, format);
}
NSArray *resultArray = [temp objectForKey:@"result"];
NSArray *loginidArray = [temp objectForKey:@"loginid"];
NSArray *usernameArray = [temp objectForKey:@"username"];
