特殊字符爲空值

我有1個數據庫。在那裏我有一個tabel。我在做這個代碼json解析。
我已經使用這個PHP代碼檢索值：特殊字符爲空值

<head> 
<style type="text/css"> 
.auto-style1 { 
    text-align: right; 
} 
</style> 
</head> 

<?php 

echo getdata($_REQUEST['lastupdate']); 

function getdata($lastupdatedate){ 


    $obj = json_decode($json); 



    $con = mysql_connect("localhost","root","Password"); 


    if (!$con) 
    { 
     die('Could not connect: ' . mysql_error()); 
    } 
    mysql_select_db("roster", $con); 

    $query = "select * from statedeathtax_v2 where LastUpdated > '".$lastupdatedate."' order by LastUpdated"; 

    $rs = mysql_query($query) or die($query); 

    //print_r($rs); 

    while($row=mysql_fetch_assoc($rs)){ 

    $record[] = $row; 

    } 



    $data = json_encode($record); 



    header('Cache-Control: no-cache, must-revalidate'); 

    header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); 

    header('Content-type: application/json'); 

    return $data; 

} 

?>

下面這段代碼並不顯示特殊字符，如「$」。當我在這段代碼中引入查詢時，它顯示具有特殊字符的列的空值。我沒有收到問題。

[ヶ輛]檢查（HTTP：/ /php.net/manual/function。 htmlentities.php）？ – StasGrin

我已經解決了概率：

更新的代碼：

<?php 

echo getdata($_REQUEST['lastupdate']); 

function getdata($lastupdatedate){ 


    $obj = json_decode($json); 



    $con = mysql_connect("localhost","root","[email protected]"); 
    mysql_set_charset('utf8',$con); 

    if (!$con) 
    { 
     die('Could not connect: ' . mysql_error()); 
    } 
    mysql_select_db("roster", $con); 

    $query = "select * from statedeathtax_v2 where LastUpdated > '".$lastupdatedate."' order by LastUpdated"; 

    $rs = mysql_query($query) or die($query); 

    //print_r($rs); 

    while($row=mysql_fetch_assoc($rs)){ 

    $record[] = $row; 

    } 



    $data = json_encode($record); 



    header('Cache-Control: no-cache, must-revalidate'); 

    header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); 

    header('Content-Type: application/json; charset=utf-8'); 

    return $data; 

} 

?>

對於mysqli_connect：

$conecta = mysqli_connect("host", "user", "pass", "dbase") 
or print (mysql_error()); 

$conecta->set_charset('utf8');
