所以这个问题可能是许多事情之一。这是我的情况。

我使用 ec2 服务器作为我的主机网站，它通过机架空间负载平衡器连接到机架空间数据库（它们不允许从机架空间外部的源连接到数据库）。

无论如何，我的问题是我试图在插入时对我的 mysql 表进行编码并在选择时对其进行解码。这是我用来进行插入的代码：

function mysql_insert_sanitize_encrypt_store($databaseName,$names,$values,$link){
$query="INSERT INTO ".$databaseName." (";
foreach($names as $name){
$query=$query.$name.",";
}
$query[strlen($query)-1]=")"; //replace trailing comma with parenthesis 
$query=$query." VALUES (";
foreach($values as $value){
$sanivalue=filter_var($value,FILTER_SANITIZE_URL);
$query=$query."ENCODE('".$sanivalue."','encryptionstring'),";
}
$query[strlen($query)-1]=")";
echo $query;
if(mysql_query($query,$link)){
return 1;
}
}

生成这样的查询：

INSERT INTO PublishedItems (PublisherUrl,Age,option,experience,goals,gender,minstaken,Item) VALUES (ENCODE('https://www.google.com/profiles/100571329423938175195','encryptionstring'),ENCODE('18-30,30-45','encryptionstring'),ENCODE('15-30','encryptionstring'),ENCODE('novice,amateur','encryptionstring'),ENCODE('Loseweight','encryptionstring'),ENCODE('male','encryptionstring'),ENCODE('120','encryptionstring'),ENCODE('[[{"name":"MW350","value":""},{"name":"MD350","value":""}]]','encryptionstring'))

这将作为成功插入返回。

当我尝试再次获取数据时，我使用以下代码：

$query="select ".$decryptionQueries[$count++]." FROM ".$DBName;
mysql_free_result($result);
$result=mysql_query($query,$link);
echo "</br>";
echo $query;
echo "</br>";
echo "decrypted result --->";
var_dump($result);
echo "</br>";
echo "</br>============".$DBName."============UNENCRYPTED=========</br>";
while($row=mysql_fetch_array($result)){
echo "</br>";
var_dump($row);
echo "</br>";
echo "<pre>" . print_r(get_defined_vars(),true) . "</pre>";
}

其中解密查询定义如下：

$decryptionQueries=array("DECODE(PublisherUrl, 'encryptionstring'), DECODE(Age,'encryptionstring'), DECODE(option,'encryptionstring'), DECODE(experience,'encryptionstring'), DECODE(goals,'encryptionstring'), DECODE(gender,'encryptionstring'),DECODE(minstaken,'encryptionstring'), DECODE(Item,'encryptionstring')","DECODE(User,'encryptionstring'), DECODE(Age,'encryptionstring'), DECODE(option,'encryptionstring'), DECODE(experience,'encryptionstring'), DECODE(goals,'encryptionstring'),DECODE(gender,'encryptionstring'), DECODE(Injuries,'encryptionstring'), DECODE(availperday,'encryptionstring'), DECODE(Item,'encryptionstring')");

这会生成如下查询：

select DECODE(PublisherUrl, 'encryptionstring'), DECODE(Age,'encryptionstring'), DECODE(option,'encryptionstring'), DECODE(experience,'encryptionstring'), DECODE(goals,'encryptionstring'), DECODE(gender,'encryptionstring'),DECODE(minstaken,'encryptionstring'), DECODE(Item,'encryptionstring') FROM PublishedItems

但是在显示数据时，rows 变量的定义变量条目如下所示：

[row] => Array
        (
            [0] => h
            [DECODE(PublisherUrl, 'encryptionstring')] => h
            [1] => 18-3
            [DECODE(Age,'encryptionstring')] => 18-3
            [2] => 15-3
            [DECODE(option,'encryptionstring')] => 15-3
            [3] => 
            [DECODE(experience,'encryptionstring')] => 
            [4] => 
            [DECODE(goals,'encryptionstring')] => 
            [5] => male
            [DECODE(gender,'encryptionstring')] => male
            [6] => 1
            [DECODE(minstaken,'encryptionstring')] => 1
            [7] => [
            [DECODE(Item,'encryptionstring')] => [

我的问题是：为什么这只返回存储在数据库中的部分字符串？或者为什么它只存储部分字符串？我的代码出了什么问题？它与编码和解码有关吗？

当输入没有首先编码并且只是从数据库中选择时，它会正确且完整地返回，所以我认为它与编码和解码有关。

你认为是什么问题？

编辑：

遍历其中一个表的行给出以下输出（我只是 var_dumped 行）

请注意，某些字符串未加密，我将其作为控件执行，这表明问题出在编码插入，但我想不出用于插入的查询字符串（请参阅第二个代码片段）如何只插入部分消息。解密后，这些字符串会给出部分字符串，如果是完整的，那将是正确的。

此外，这里是表的声明：

create table PublishedItemss (PublisherUrl char(150),Age char(5),option char(8),experience char(20), goals char(50), gender char(8), minsTaken int, item TEXT,DateSubmitted timestamp NOT NULL DEFAULT NOW())';
