怎样从mysql数据库中读取数据，并保存到数组？

给你写了段代码.主读取在get_data函数中.
define("HOST", "localhost");
define("DB", "demo");
define("DBUSER", "root");
define("DBPASSWD", "mysql");
$local_conn = mysql_connect(HOST,DBUSER,DBPASSWD);
if(!isset($local_conn)) exit();
mysql_select_db(DB);
$sql = "set names utf8";
mysql_query($sql,$local_conn);
function get_data($conn,$name){
$sql = "select * from t_demo where time like'".$name."'";
$resultRows = @mysql_query($sql,$conn);
while($trow = @mysql_fetch_array($resultRows)){
$result[] = $trow;
}
mysql_free_result($resultRows);
return $result;
}
$result = get_data($local_conn,"test");
?>

StringBuffer是可变长的数组，循环取值赋值就可了

循环赋值就得了
