//要过滤的非法字符
$ArrFiltrate=array("'",";","union");

//出错后要跳转的url,不填则默认前一页
$StrGoUrl="";

//是否存在数组中的值
function FunStringExist($StrFiltrate,$ArrFiltrate){
 foreach ($ArrFiltrate as $key=>$value){
  if (eregi($value,$StrFiltrate)){
   return true;
  }
 }
 return false;
}


//合并$_POST 和 $_GET


if(function_exists(array_merge)){


$ArrPostAndGet=array_merge($HTTP_POST_VARS,$HTTP_GET_VARS);


}else{


foreach($HTTP_POST_VARS as $key=>$value){


$ArrPostAndGet[]=$value;


}


foreach($HTTP_GET_VARS as $key=>$value){


$ArrPostAndGet[]=$value;


}


}


//验证开始


foreach($ArrPostAndGet as $key=>$value){


if (FunStringExist($value,$ArrFiltrate)){


//echo "";


if (empty($StrGoUrl)){


echo "";


}else{


echo "";


}


exit;


}
