准备好的语句将 \ 放在  之前

Question

我使用准备好的语句来解扰 BBcode，但由于某种原因，它在发布时将 \ 放在 ' 之前。我不知道是什么原因导致的，但我确信当我将 BBcode 更改为 html 放入数据库时​​会发生这种情况，代码如下所示：

$text = $membership->remove_HTML($text);


    //convert line breaks to <br /> tags.
      $text = nl2br($text);

      //cleans up by removing white space.
      $text = trim($text);

      //now lets replace things BASIC EDITOR
      $text = preg_replace("/\[b\](.*)\[\/b\]/", "<strong>\\1</strong>", $text);
      $text = preg_replace("/\[i\](.*)\[\/i\]/", "<em>\\1</em>", $text);
      $text = preg_replace("/\[u\](.*)\[\/u\]/", "<span style='text-decoration:underline;'>\\1</span>", $text);
      $text = preg_replace("/\[s\](.*)\[\/s\]/", "<del>\\1</del>", $text);

      $text = preg_replace("/\[url\](.*)\[\/url\]/", "<a target='_blank' href='\\1'>\\1</a>", $text);
      $text = preg_replace("/\[url=(.*)\](.*)\[\/url\]/", "<a target='_blank' rel='\\1' href='\\1'>\\2</a>", $text);

      //now lets replace MORE things EXPANDED EDITOR
      $text = preg_replace("/\[img\](.*)\[\/img\]/", "<img>\\1</img>", $text);
      $text = str_ireplace("[hr]","<hr>", $text);
      $text = preg_replace("/\[justify\](.*)\[\/justify\]/", "<p style='text-align:justify;'>\\1</p>", $text);
      $text = preg_replace("/\[center\](.*)\[\/center\]/", "<p style='text-align:center;'>\\1</p>", $text);
      $text = preg_replace("/\[left\](.*)\[\/left\]/", "<p style='text-align:left;'>\\1</p>", $text);
      $text = preg_replace("/\[right\](.*)\[\/right\]/", "<p style='text-align:right;'>\\1</p>", $text);
      $text = preg_replace("/\[h1\](.*)\[\/h1\]/", "<h4>\\1</h4>", $text);
      $text = preg_replace("/\[h2\](.*)\[\/h2\]/", "<h5>\\1</h5>", $text);
      $text = preg_replace("/\[h3\](.*)\[\/h3\]/", "<h6>\\1</h6>", $text);

      $updatenews = $mysql->add_news($_SESSION['user'][0], $headline, $text, $time);

最快的检查方法是确保 PHP 的 Magic Quotes 已禁用 。

如果您不想直接修改 PHP 配置，请在滚动 $text 一系列 preg_replaces().
