What is the best way to pass data input from an iphone app to a php file?

Answer 1

A NSURLRequest POST or GET call to the php file.

- (void) <functionname>:<parameters> {   
    NSString *urlString = [NSString stringWithFormat:@"<url with GET>",<parameters>];
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlString]];  NSError * e; 
    NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&e];
    return [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 
}
