MySQL在特殊字符处切断字符串

Question

我正在尝试使用PHP将远程POST数据(iSnare发送的文章)插入MySQL.数据来自远程POST发件人,我可以将其写入纯文本文件而不会出现问题.

不幸的是,当它将它插入MySQL时,MySQL会在特殊字符处切断字符串(文章).我尝试过很多东西,但我还是不成功!

我试过了:

• 逃避角色 mysql_real_escape_string()
• 使用htmlentities()和htmlspecialchars()(与每个参数..)
• SET NAMES utf8在执行其他所有操作之前向MySQL 发送查询
• 所有表和列都是UTF-8编码的utf8_general_ci(也尝试过utf8_unicode_ci并utf8_bin作为整理)
• 将所有PHP文件保存为UTF-8

我仍然找不到解决方案.如果有人能帮助我解决这个问题,我将非常感激.

这是我的表定义和PHP代码:

PHP

function guvenlik_sql($x){

    // Cleans inputs agains sql injection
    return mysql_real_escape_string(htmlentities(stripslashes($x)), ENT_QUOTES);
}    

// Check if data really comes from an Isnare.com server (Address hidden)
if ($_SERVER['REMOTE_ADDR'] == $isnareIP || $_SERVER['REMOTE_ADDR'] == "xxx.xxx.xxx.xxx") {

    $title = guvenlik_sql($_POST["article_title"]);
    $first_name = guvenlik_sql($_POST["article_author"]);
    $description = guvenlik_sql($_POST["article_summary"]);
    $category = guvenlik_sql($_POST["article_category"]);
    $article = guvenlik_sql($_REQUEST["article_body_text"]);
    $article_html = guvenlik_sql($_POST["article_body_html"]);
    $resource_box = guvenlik_sql($_POST["article_bio_text"]);
    $resource_box_html = guvenlik_sql($_POST["article_bio_html"]);
    $keywords = guvenlik_sql($_POST["article_keywords"]);
    $email = guvenlik_sql($_POST["article_email"]);

    $fp = fopen('test.txt', 'a');
    fwrite($fp, $title."\n");
    fwrite($fp, $article."\n\n\n\n");
    fclose($fp);

mysql_query("INSERT INTO articles " . 
            "(" . 
                "first_name, " . 
                "email, " .

                "'$_SERVER['REMOTE_ADDR']', " . 
            ")") or die(mysql_error());

我刚刚处理了相同的情况,条目被截断,特殊字符(ä,ö,è等)应该是.我的所有文件都是UTF8编码,连接是UTF8编码,表格归类是UTF8,但条目仍被截断.

我的解决方案是:甚至更多的UTF编码!:)用于utf8_encode()可以包含特殊字符的条目.

mysql_query("INSERT INTO articles (first_name, email, title, description, article, article_html, category, resource_box, resource_box_html, keywords, distributor, distributor_host) values (
                                  '" . utf8_encode($first_name) . "',
                                  '" . $email . "',
                                  '" . utf8_encode($title) . "',
                                  '" . utf8_encode($description) . "',
                                  // etc

“设置名称 utf8”仅设置表名和列名的字符集，对于内容字符集，您也必须使用“设置字符集 utf8”。
