屏蔽敏感词

public function sensitive($text)
{
if($texttext)
{
$text = @file_get_contents('guolv.txt');//获取敏感词文件包
$sen = iconv("GBK", "UTF-8", $text);//转成中文
$arr = explode('={BANNED}',$sen); //炸开成数组
foreach ($arr as $k => $v)
{
$v = trim($v);
$strs = str_replace($v,'***',$text);//替换
$text = $strs;
}
}
return $text; //返回
}
