\\\\ [R \\\\ň\\\\ [R \\\\ň文本之後出現的字符插入形式PHP

Question

我有處理文本像這樣的形式：

$group_description = mysql_real_escape_string(trim($_POST['group_description'])); 

$insert_group_sql = 'INSERT INTO table_name(group_description) 
VALUES ("'.$group_description.'" ') '; 

和輸出分貝結果這樣的另一頁：

$group_description = $row['group_description']; 

//Convert all urls to links 
$group_description = preg_replace('#([\s|^])(www)#i', '$1http://$2', $group_description); 
$pattern = '#((http|https|ftp|telnet|news|gopher|file|wais):\/\/[^\s]+)#i'; 
$replacement = '<a href="$1" target="_blank">$1</a>'; 
$group_description = preg_replace($pattern, $replacement, $group_description); 

$group_description = str_replace(array('\r\n', '\n\r'), '<br />',$group_description); 

/* Convert all E-mail matches to appropriate HTML links */ 
$pattern = '#([0-9a-z]([-_.]?[0-9a-z])*@[0-9a-z]([-.]?[0-9a-z])*\\.'; 
$pattern .= '[a-wyz][a-z](fo|g|l|m|mes|o|op|pa|ro|seum|t|u|v|z)?)#i'; 
$replacement = '<a href="mailto:\\1">\\1</a>'; 
$group_description = preg_replace($pattern, $replacement, $group_description); 

我最終什麼樣的主意是這樣的頁面：http://www.comehike.com/hikes/hiking_group.php?hiking_group_id=54

而且我也不太清楚這個使用者如何得到\\ \\ [R n個字符去那裏:)

任何想法出錯的地方？如果這很重要，我使用MySQL數據庫。謝謝！

請閱讀PHP magic quotes，然後考慮升級php版本。
