$abcs = mb_convert_encoding(trim($_POST["key"]),"utf-8","gb2312"); //接收传送过来的关键值
$skey = file_get_contents("http://suggestion.*b**aidu.com/su?wd=".urlencode($abcs).""); //访问百度页面

preg_match('/＼[(.*?)＼]/',$skey,$m); //通过正则去掉
$s = explode(',',$m[1]);
foreach($s as $k=>$v){
$s[$k] = substr($v,1,-1);
}
var_dump($s); //输出
