/*

/**

 */
class checkURL{
   function inject_check($get) {
   $checkurl=eregi('select|insert|update|delete|\'|\/\*|\*|\.\.\/|\.\/|union|into|load_file|outfile|or|and|-||&|%|limit|where|oR|aNd', $get);//要匹配的字符
   if($checkurl)
   {
     echo "<script>alert('使用非法字符!请文明上网,文明上网');location.href='' http://www.mps.gov.cn/n16/n1966474/“;</script>";
    
     exit();
   }else
   {
     return $get;
   }
}

}

调用方法

require_once 'url/checksql.php';                         //根据自己的路径

$check=new checkURL();                                     //创建对象
$id=$check->inject_check($_GET['id']);           //将url传入的参数 传入调用的正则方法

参数$id 匹配过后可以去传入自定义方法使用

以上方法 如有问题或是其他的更好的意见及建议 欢迎大家一起交流
