php-阿拉伯文本存储为“ ???”

我正在尝试将阿拉伯文本保存在My SQL中.

我的SQL表的排序规则为utf8_general_ci

我在iPhone应用程序中有文本字段,并且正在使用PHP保存数据.

PHP代码如下所示.

$con = mysql_connect(localhost, $username, $password);
@mysql_select_db($database) or die("Unable to select database");


$propType = $_POST['propType'];
$price = $_POST['price'];
$type = $_POST['type'];
$zone = $_POST['zone'];
$location = $_POST['location'];
$no_floor = $_POST['no_floor'];
$no_apt = $_POST['no_apt'];
$basement = $_POST['basement'];
$area = $_POST['area'];
$addedBy = $_POST['addedBy'];
$imagePath = $_POST['imagePath'];
$saleType = $_POST['dummy001'];
$mauka = $_POST['mauka'];
$mobileNumForDial = "0";


$result = mysql_query("SELECT mobileNumber FROM userInfo WHERE username='$addedBy'");
while($data = mysql_fetch_row($result)){
    $mobileNumForDial=$data[0];
}

$sql = mysql_query("INSERT INTO buildingData (propType, price, type, zone, location, no_floor,
        no_apt, basement, area, addedBy, imagePath, dummy001, dummy002, mauka) 
        VALUES 
        ('$propType', '$price', '$type', '$zone', '$location', '$no_floor', '$no_apt', '$basement', 
        '$area','$mobileNumForDial','$imagePath', '$saleType', '', '$mauka')");

iPhone代码如下所示

if ([btnImage.accessibilityIdentifier isEqualToString:@"no_image"]) {
    imageSet = @"missing";
} else {
    imageSet = @"set";
}
post = [[NSString alloc] initWithFormat:@"propType=%d&price=%@&type=%d&zone=%d&location=%d&no_floor=%d&no_apt=%d&basement=%d&area=%@&addedBy=%@&imagePath=%@&dummy001=%d&mauka=%@",
        realEstatePV.selectedItem,
        priceData.text,
        typePV.selectedItem,
        areaPV.selectedItem,
        regionPV.selectedItem,
        floorData.text.intValue,
        aptData.text.intValue,
        basementPV.selectedItem,
        areaData.text,
        [keychainItem objectForKey:kSecAttrAccount],
        imageSet, salePV.selectedItem, mauka.text];
postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

postLength = [NSString stringWithFormat:@"%d", [postData length]];

url = [NSURL URLWithString:@"http://www.smart-kw.com/sama/saveBldgData.php"];

NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
[theRequest setHTTPMethod:@"POST"];
[theRequest setValue:postLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPBody:postData];


NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

if( theConnection )
{
    indicator.hidden = NO;
    [indicator startAnimating];
    webData = [[NSMutableData data] retain];
}
else
{
    NSLog(@"Internet problem maybe...");
}

问题是

当我存储英语数据时,这很好.

但是,当我输入阿拉伯文字时,它会被存储为???.在mysql数据库中.

知道为什么会这样吗？

编辑1

我也在下面尝试过,但仍然将数据存储为* ???

mysql_query("SET NAMES 'utf8'"); 
mysql_query('SET CHARACTER SET utf8');

$sql = mysql_query("INSERT INTO buildingData (propType, price, type, zone, location, no_floor,
        no_apt, basement, area, addedBy, imagePath, dummy001, dummy002, mauka) 
        VALUES 
        ('$propType', '$price', '$type', '$zone', '$location', '$no_floor', '$no_apt', '$basement', 
        '$area','$mobileNumForDial','$imagePath', '$saleType', '', '$mauka')");

解决方法:

尝试将postData设置为使用UTF 8而不是ASCII编码进行编码：

postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
