PHP 无法从数据库中获取 UTF8

Question

我正在为搜索结果使用 ajax 分页方法。在将 mysql 项目设置为连接并为此设置 utf8 之后，我的结果不是 utf8 unicode，

我的 dabtabase 数据是 utf8 并且正确保存。但是在获取之后我无法使用正确的 unicode。

我在本地主机上没有问题但是在服务器上上传文件后我有问题

JQUERY :

$(document).ready(function(){
    $('#searchWordButton').click(function(){
        searchWord = $('#searchWord').val();
        if ( $.trim(searchWord) =='' ){
            alert('input is empty...');
            return false;
        } 
        else{
        $('[id^="hidden_div"]').hide();
            $('.div_search').show();                
            function loadData(page){
                $.ajax
                ({
                    type: "POST",
                    url: "load_data.php",
                    data: "page="+page+"&word="+searchWord,
                    success: function(msg)
                    {
                        $("#search_container").html(msg);
                    }
                });
            }
            loadData(1);  // For first time page load default results
            $('#search_container').on('click','.pagination li.active',function(){
                var page = $(this).attr('p');
                loadData(page);
            });                             
        }

    });

PHP 加载数据.php :

<?php

$cur_page = $page;
$page -= 1;

$query_pag_data = "SELECT id as msg_id ,subject as message , description from contents WHERE subject like '%$word%' LIMIT $start, $per_page";
$result_pag_data = mysql_query($query_pag_data) or die('MySql Error' . mysql_error());

$no_of_paginations = ceil($count / $per_page);

if ($cur_page >= 7) {
    $start_loop = $cur_page - 3;
    if ($no_of_paginations > $cur_page + 3)

尝试在 <?php 之后添加这一行

header('Content-Type: text/plain; charset=utf-8');
