PHP长时间连接数据库造成mysql has gone away
public function connect() {
if ($this->conn == "pconn") {
//永久链接
$this->conn = mysql_pconnect($this->db_host, $this->db_user, $this->db_pwd);
} else {
//即使链接
$this->conn = mysql_connect($this->db_host, $this->db_user, $this->db_pwd);
}

if (!mysql_select_db($this->db_database, $this->conn)) {
if ($this->show_error) {
$this->show_error("数据库不可用:", $this->db_database);
}
}
mysql_query("SET NAMES $this->coding");
}

上面贴的是数据库连接的写法,请问怎么写能做到不出现错误呢?还有其他的方法吗?
