query使用

1.row_array()：返回查詢結果中的第一條數據

include APP_PATH . "../mysql.class.php";
$db = new mysql();
$sql ="select userid,appid,appsecret,authfields,authfilters,loanid,finid,apitype from boc_user_api where appid='$appid'";
$memberinfo = $db->row_array($sql);

2.result_array()：以數組的形式返回所有的查詢結果

include APP_PATH . "../mysql.class.php";
$db = new mysql();
$sql ="select userid,appid,appsecret,authfields,authfilters,loanid,finid,apitype from boc_user_api where appid='$appid'";
$memberinfo = $db->result_array($sql);

 3.query()：執行非查詢之外的sql語句

include APP_PATH . "../mysql.class.php";
$db = new mysql();
$sql ="insert into user (name,age) values ('花花',18)";
$ret = $db->query($sql);
