mysql连接操作
//建立连接
$con = mysql_connect('localhost', 'root', '123456');
//判断是否连接成功
if($con){
die('连接失败!'.mysql_error());
exit;
}
//选择字符集
mysql_set_charset('utf8', $con);
//选择数据库
mysql_select_db('test', $con);
$sql = '.........................';
//执行sql语句
$result = mysql_query($sql, $con);
//如果是插入操作
mysql_affected_rows() 获取影响行数
mysql_insert_id() 获取新插入的ID
//如果是查询操作
while($row = mysql_fetch_assoc($result)){
echo '<pre>';
var_dump($row);
echo '</pre>';
}
//关闭数据库
mysql_close($con);
