/*

$fcon = file_get_contents("./filter.txt");

$filter_word = explode("\n",$fcon);

*/

$filter_word = file("./filter.txt");

//$filter_word = array("test1","test2","test3","test4");

$str = $_POST["mess"];

for($i=0;$i

{

if(preg_match("/".(trim($filter_word[$i]))."/i",$str))

{

echo "";

echo "返回";

exit;

}

echo "您输入的内容是:".$str;

}
