上传文件到http服务器时出现错误。下面是我使用的代码：objective-c将png文件上传到http
UIImage * ourImage = [UIImage imageNamed:@"tux.png"];
NSData * imageData = UIImageJPEGRepresentation(ourImage, 1.0);
NSString *urlString = @"http://www.site.com/imageupload.php";
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
NSMutableData *body = [NSMutableData data];
NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
[request addValue:contentType forHTTPHeaderField:@"Content-Type"];
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Disposition: attachment; name=\"userfile\"; filename=\".png\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
// Text parameter1
NSString *param1 = @"parameter text";
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"parameter1\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:param1] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
// Another text parameter
NSString *param2 = @"Parameter 2 text";
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"parameter2\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:param2] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
// close form
[body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// set request body
[request setHTTPBody:body];
//return and test
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"%@", returnString);
，这是我在服务器中的public_html /目录下的PHP文件。文件名是imageupload.php。我正尝试通过HTTP上传图片文件，而不是使用任何名称或密码登录。我不熟悉PHP，真的需要一些帮助。谢谢。
<?php
$uploaddir = '/public_html/upload';
$file = basename($_FILES['userfile']['name']);
$uploadFile = $file;
$randomNumber = rand(0, 99999);
$newName = $uploadDir . $uploadFile;
if (is_uploaded_file($_FILES['userfile']['tmp_name'])) {
echo "Temp file uploaded. \r\n";
} else {
echo "Temp file not uploaded. \r\n";
}
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $newName)) {
$postsize = ini_get('post_max_size'); //Not necessary, I was using these
$canupload = ini_get('file_uploads'); //server variables to see what was
$tempdir = ini_get('upload_tmp_dir'); //going wrong.
$maxsize = ini_get('upload_max_filesize');
echo "http://www.iroboticshowoff.com/dir/{$file}" . "\r\n" . $_FILES['userfile']
['size'] . "\r\n" . $_FILES['userfile']['type'] ;
}
?>
，这是我从服务器取回的错误，当我执行的代码：

PHP错误消息
解析错误：语法错误，在/home/a5054180/public_html/imageupload.php意外T_STRING上线
免费虚拟主机ing
加上其他错误。任何人都可以尝试一下，让我知道我能做些什么来解决它。非常感谢，谢谢。
