PHP采集的实现，直接写成个类
很多朋友都想自己的cms有采集的功能，这样省时省力，今天就分享一个朋友写的采集类，我也没怎么看过，大家可以自己研究一下，如果不会，可以加QQ2387813033，一起讨论学习，或者加群252799167

数据库类：
class Mysql{
private $host;
private $user;
private $pwd;
function __construct($host,$user,$pwd,$db,$un="utf8"){
$this->host = $host;
$this->user = $user;
$this->pwd = $pwd;
$this->db = $db;
$this->un = $un;
$this->conn();
}
function conn(){
$conn = mysql_connect($this->host,$this->user,$this->pwd) or die(("ᬽó꧰ü").mysql_error());
mysql_select_db($this->db,$conn) or die("êy¾Y¿a2»′æÔú".mysql_error());
mysql_query("set character set $this->un");
mysql_query("set names $this->un");
}
function select($table,$where="",$num=false){
$query = mysql_query("select * from `$table` $where");
while($row = mysql_fetch_array($query)){
$arr[] = $row;
}
if($num){
return $arr[0];
}else{
return $arr;
}
}
function num_rows($table,$where=""){
$query = mysql_query("select * from `$table` $where");
$num = mysql_num_rows($query);
return $num;
}
function insert($table,$name="",$value){
mysql_query("INSERT INTO `$table` ($name) VALUES ($value)");
}
function update($table,$fn,$where=""){
mysql_query("UPDATE $table SET $fn $where");
}
function close(){
return mysql_close();
}
}
