我的查询字符串是$SQLstring = "SELECT name, address, city, state, zip, homephone, cellphone, position, shift, status, workedherebefore, previousemploymentdate, referred, empname, under18, friends, empname2, currentlyemployed, contactemployer, lawful, worktime, workweekends, dateavailable, desiredsalary, position1, from1, to1, duties1, company1, cophone1, startsalary, endsalary, reasonleaving1, supervisor1, contact1, position2, from2, to2, duties2, company2, cophone2, startsalary2, endsalary2, reasonleaving2, supervisor2, contact2, position3, from3, to3, duties3, company3, cophone3, startsalary3, endsalary3, reasonleaving3, supervisor3, contact3, comments, training, otherqual, documents, dltype, dlstate, expdate, yearsdriving, movingviolations, hsname, hscity, hsstate, hsdates, collegename, collegecity, collegestate, collegedates, othername, othercity, otherstate, otherdates, licenseorcert, refname1, refbusiness1, reftitle1, refaddress1, refphone1, refname2, refbusiness2, reftitle2, refaddress2, refphone2, refname3, refbusiness3, reftitle3, refaddress3, refphone3,felony, iffelony, fired, iffired, resident, explanation, signed, q1, q2, q3, q4, mq1, mq2, mq3, mq4, mq5, mq6, mq7, mq8, mq9, mq10, mq11, mq12, mq13, mq14, mq15, mq16, mq17, mq18, mq19, mq20, mq21, mq22, mq23, mq24, mq24b, mq25, mq25b, mq26, mq27a, mq27b, mq27c, mq28, mq29, mq30answer, disclosuresig, verify_name, other_names, dob, AES_DECRYPT(ssn,'$key') AS ssn FROM applications";

我查询结果，然后将它们返回到表中。除了 AES_DECRYPT 字段 (ssn) 之外，所有这些都有效。在数据库中，它似乎已被很好地加密，但查询中的此字段返回为空白。这是其余的代码，以防万一：

$key="88b871WZ3SntWK67rN3l2J1SvMqsOjyk";
$QueryResult = @mysql_query($SQLstring, $conn) or die("Query Problem - " . mysql_error($conn) . " - Error Number - " . mysql_errno($conn));

        $num_result = mysql_num_rows($QueryResult);

        echo "<table>";

        for ($i = 0; $i < $num_result; $i++)    
        {
            $row = mysql_fetch_array($QueryResult);

要使用 AES_ENCRYPT 和 AES_DECRYPT，字段类型必须是 BLOB。我将它设置为 VARCHAR 并且它无法识别某些字符。将字段类型更改为 blob 效果很好。

如果检测到无效数据，MySQL AES_DECRYPT() 返回 NULL。
所以传递给 AES_DECRYPT() 的字符串是无效的。
在这种情况下，我建议 ECHO/alert 查询，以便您可以看到一切都是正确的。最可能的错误是 AD7six 指出的...... $key 可能是空的。

$key="88b871WZ3SntWK67rN3l2J1SvMqsOjyk";
$SQLstring = "SELECT * FROM table"; // Replace with your Query
echo $SQLstring;
$QueryResult = @mysql_query($SQLstring, $conn) or die("Query Problem - " . mysql_error($conn) . " - Error Number - " . mysql_errno($conn));

警报器：

echo "<script type='text/javascript'>
alert($SQLstring);
</script>";

我还建议您阅读有关mysqli的信息
