PHP PDO斜杠导致错误问题

使用PDO出现了一个问题，当字符的最后一个为\的时候插入数据库失败，很是费解，参数绑定怎么会出现如此的问题？

error_reporting(E_ALL);
header("content-type:text/html;charset=utf8");

$params = array();

$params[PDO::MYSQL_ATTR_INIT_COMMAND] = 'SET NAMES UTF8';

$dsn = "mysql:host=localhost;dbname=test;port=3306;";
$dbh = new PDO($dsn, 'root', '123456', $params);

$sql = 'INSERT INTO `fav_ls_1` (`uid`,`fid`,`type`,`title_md5`,`title`,`url`,`order`,`addtime`) VALUES (:uid,:fid,:type,:title_md5,:title,:url,:order,:addtime)';
$bind = array(
    ':uid' => 5919639,
    ':fid' => 0,
    ':type' => 1,
    ':title_md5' => "0886c9605d1424e656c85736b4730e7f",
    ':title' => '\\敌\\',
    ':url' => "http://www.2345.com/?ie",
    ':order' => 0,
    ':addtime' => 1449156098,
);

$sth = $dbh->prepare($sql);
if(false===$sth->execute($bind))
{
 print_r(  $sth->errorInfo () );
}
else
{
    echo  $dbh->lastInsertId();
}

错误代码如下：

Array ( [0] => 42000 [1] => 1064 [2] => You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'http://www.2345.com/?ie','0','1449156098')' at line 1 )

补充一下：
这个设置了$dbh->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);就可以运行了，但是在其他sql上也会出现莫名其妙的错误。

感谢king同学的答案：
我的问题是PHP环境是大于5.3.6的，需要在dsn中设置charset=utf8,低于PHP5.3.6版本的使用SET NAMES UTF8
修改代码如下解决：

public function connect($config, $linkNum) 
{
    if(empty($this->_link[$linkNum]))
    {
        if(empty($config)) $config = $this->config;
        
        $params = array();
        
        //  PHP<=5.3.6使用此方法设置编码
        if(!empty($config['db_charset']) && version_compare(PHP_VERSION,'5.3.6','<='))
            $params[PDO::MYSQL_ATTR_INIT_COMMAND] = 'SET NAMES ' . $config['db_charset'];
        
        // 长链接
        if(isset($config['db_params']['pconnect']) && $config['db_params']['pconnect'] == true)
            $params[PDO::ATTR_PERSISTENT] = true;
        
        // @link http://zhangxugg-163-com.iteye.com/blog/1835721 5.3.6下有bug
        if(version_compare(PHP_VERSION,'5.3.6','<='))
            $params[PDO::ATTR_EMULATE_PREPARES]  =   false; // 禁用模拟预处理语句
        
        // php 5.3.6+在PDO的DSN中指定charset属性
        $dsn_charset = version_compare(PHP_VERSION, '5.3.6', '>') ? "charset={$config['db_charset']};" : '';
        
        $dsn = "{$config['db_type']}:dbname={$config['db_name']};host={$config['db_host']};port={$config['db_port']};" . $dsn_charset;
        $this->dbName = $config['db_name'];
        $this->dbType = $config['db_type'];
        
        try
        {
            $this->_link[$linkNum]  = new PDO($dsn, $config['db_user'], $config['db_pass'], $params);
            $this->_link[$linkNum]->setAttribute(PDO::ATTR_CASE, PDO::CASE_LOWER);
            $this->_link[$linkNum]->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC);
        }
        catch(PDOException $e)
        {
            throw new CException($e->getMessage());
        }
    }
    
    $this->_linkId = $this->_link[$linkNum];
    return $this->_linkId;
}
