Do a HTTPResponse in PHP

How I can make a HTTPResponse in php? I'm having some trouble :( I should read the response from a cocoa application. This is my php code:

<?php
HttpResponse::setCache(true);
HttpResponse::setContentType('text/plain');       
HttpResponse::setData("Some data");
HttpResponse::send();
?>

Then here is my Cocoa Code:

- (void)viewDidLoad
{
    [super viewDidLoad];
    [self.view setBackgroundColor:[UIColor whiteColor]];
    NSURL *url = [NSURL URLWithString:@"Web site"];
    NSURLRequest *theRequest开发者_Go百科=[NSURLRequest requestWithURL:url
                                              cachePolicy:NSURLRequestUseProtocolCachePolicy
                                          timeoutInterval:60.0];
        // create the connection with the request
        // and start loading the data
    NSURLConnection *theConnection=[[[NSURLConnection alloc] initWithRequest:theRequest delegate:self] autorelease];
    if (theConnection) {
        receivedData = [[[NSMutableData data] retain] autorelease];
        NSLog(@"OK!");
    } else {
        NSLog(@":(((");
    }

}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
        // Append the new data to receivedData.
        // receivedData is an instance variable declared elsewhere.
    NSLog(@"DATA");
    NSString* aStr;
    aStr = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
    NSLog(@"%@",aStr);
}

But it doesn't work :( Ideas?

The http library is not included with PHP by default as detailed on this page of the manual http://www.php.net/manual/en/http.install.php, so you probably need to install it on your system.

The 'not found' error suggests that you haven't installed it yet, so you need to follow the steps in the instructions.
