php – 用双引号括起字符串

我已经检查了以前的线程.

这是代码：

检查结果：http://ideone.com/gWFdUb

<?php
function clean($string) {
    eval('$string = "'.$string.'";');
   $string = str_replace(' ',' ',$string); // Replaces all spaces with hyphens.
   return preg_replace('/[^A-Za-z0-9 @-]/','',$string); // Removes special chars.
}

$d =  clean('this was readlly n'ice 'test for@me to') ;
echo $d;

评估线有什么问题？

我正在处理用户推文,发布有两个目的.

>存储到mysql表中. (mysqli_real_escape)没有帮助
>将每个字符串处理为文本以进行匹配和POS(词性)标记.

由于文字中的这些字符,我卡住了.所以在我开始处理之前尝试删除它.

更新：

检查一下,这里我已经在使用mysqli_real_escape_String,即使脚本在达到此目的时停止

提到181有什么不对,所以它被卡住了？这是代码

foreach ($tweets1 as $item)
    {       
        $count = $count + 1;
        $text = $item->text;
        //echo $userid.$text;
        $text_id = $item->id;
        $constant = 'mention';
        $time = $item->created_at;
        //echo $time;
        //$dt = new DateTime('@' . strtotime($time));
        $dt = DateTime::createFromFormat('D M d H:i:s e Y',$time);
        //var_dump($dt);
        $tweet_time = $dt->format('H:m:s');
        $tweet_dtm = $dt->format('Y:m:d');
        $year =  $dt->format('Y'); 
        $month =  $dt->format('m'); 
        $user_name = $item->user->name;
//      echo $year.$month.$user_name;
        $inreplyto =  $item->in_reply_to_screen_name;
        $rt_count = $item->retweet_count;
        $follower_count = $item->user->followers_count;
        echo $constant."-".$count."<br>".$text."-".$text_id."-".$time."-".$tweet_time.$tweet_dtm.$year.$month.$user_name.$rt_count.$follower_count."<br>";
        echo "<br>";
        $con = mysqli_connect('127.0.0.1','root','root');         
        if (mysqli_connect_errno())
        {
            echo "Failed to connect to MySQL: " . mysqli_connect_error();
            return;
        }
        $text = mysqli_real_escape_string($con,$text);
        $insertQuery1 = "INSERT INTO twitter_mention(`username`,`userid`,`tweet_text`,`text_id`,`time`,`month`,`year`,`date`,`user_follower_count`,`rt_count`,`constant`,`in_reply_to`) VALUES ('".$twitteruser."','".$userid."','".$text."','".$text_id."','".$tweet_time."','".$month."','".$year."','".$tweet_dtm."','".$follower_count."','".$rt_count."','".$constant."','".$inreplyto."')";

        if (!mysqli_query($con,$insertQuery1))
        {
        //  die('Error: ' . mysqli_error($con));
        //  echo "error";
        }
