我一次得到一排。 (我正在使用REST API邮递员查看输出)
{
"error":false,
"uid":"5af96e2e2d1000.15095126",
"Generalnotice":{
"id":1,
"headline":"N4",
"link":"n4.in",
"description":"n4 desc",
"issued_at":"",
"updated_at":null,
"type":"general"
}
}
但是我想一次获取所有行。我不知道将while循环放在哪里。所有的互联网教程都带有mysql函数。
这是我的代码。 让我让您了解流程和我的需求。 我正在将字符串请求从android应用发送到php,这是我在fetchnotice.php文件(第4行)中收到的。然后我在另一个文件DB_Funtions.php中调用getGeneralNotice()函数 getGeneralNotice函数中的请求过程,其中我从数据库中获取数据并返回FetchNotice.php。如果我收到任何回复,请打印出来。.
我得到回应。但只有一排。我希望所有行都打印。 (不,我没有使用PDO)
