Question

我正在将我的网站从一台服务器移动到另一台服务器。我已导出旧的php数据库并将其导入新服务器。数据库名称和登录保持不变（暂时）。目前数据库中有2个表。对于一个我的PHP请求工作完全正常，一个它没有，我不知道什么可能是错的。登录文件不会抛出错误，因此它们似乎工作正常。有人可以帮忙吗？这是不起作用的代码：

    <?php
    ini_set('display_errors', 1);

//phpinfo();
    require '.ht-loginWriting.php';
    $myquery="SELECT ID, title, shortDescription, text,date, referenceProject, workshop, otherTag FROM writings";
    $query=mysql_query($myquery);
    if(! $myquery){
        echo mysql_error();
        die;
    }
    $data=array();
    for($x=0; $x < mysql_num_rows($query); $x++){
        $data[]=mysql_fetch_assoc($query);
    }
    echo json_encode($data);


?>

.HT-loginWriting.php

    <?php
    $dbhost = 'localhost:3036';
    $dbuser = 'username';
    $dbpass = 'pw';
    $database= 'urbanalphabets';
    $table  = 'writings';
    $conn = mysql_connect($dbhost, $dbuser, $dbpass);
    $db_found = mysql_select_db($database);

if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
?>

这是有效的代码：

    <?php
    ini_set('display_errors', 1);

//phpinfo();
    require '.ht-loginChangeLog.php';

    $myquery="SELECT ID, title, time, text, tag_iOS, tag_web, tag_android, tag_other FROM changeLog";
    $query=mysql_query($myquery);

    if(! $myquery){
        echo mysql_error();
        die;
    }

    $data=array();

    for($x=0; $x < mysql_num_rows($query); $x++){
        $data[]=mysql_fetch_assoc($query);
    }
    echo json_encode($data);


?>

.HT-loginChangeLog.php

<?php
    $dbhost = 'localhost:3036';
    $dbuser = 'username';
    $dbpass = 'pw';
    $database= 'urbanalphabets';
    $table  = 'changeLog';
    $conn = mysql_connect($dbhost, $dbuser, $dbpass);
    $db_found = mysql_select_db($database);


if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
?>

使用建议转换为utf-8的函数后，下面的ajax请求会抛出错误：

$.ajax ( {
       url: theURL,
       dataType: "json",
       success: function ( data, textStatus, jqXHR ) {
          console.log(data);
          console.log("sucess");
           receivedData=data;
           console.log(receivedData[0].ID, receivedData[0].title, receivedData[0].shortDescription, receivedData[0].text, receivedData[0].date, "length", receivedData.length);
           initialize();
       },
       error:function(  jqXHR,  textStatus,  errorThrown ){
                  console.log("failing");
                  console.log(jqXHR);
                  console.log(errorThrown);
                  console.log(textStatus);
       }
   } );

错误：

嗯，经过很多评论后，这里是你的答案（最有可能）

通常，它是json_encode的编码问题。你需要拥有UTF8中的所有内容。

您可以查看将字符串转换为UTF-8 here的好方法。

编辑：

我已经考虑过了。将数据库移动到新服务器时，您可能会意外地弄乱编码。它发生了一段时间。

您可以导出数据库转储，在某些程序中转换为UTF-8，如NotePad ++，然后将其还原回服务器。这是一个快速修复。

此外，您可能会考虑开始使用一些框架，例如CodeIgniter或Yii或Symphony，它们将为您完成大部分工作。编写纯PHP是很困难的并使用框架，其中有一些示例可能对您来说更容易，除非您正在尝试学习如何在PHP中编码。
