我創建了一個從SQL中提取數據並將其轉換爲JSON的函數,但是當我打印數據時,它只返回一行。當我從PHP函數打印JSON時,它只打印SQL中的一行
Db_functions.php
public function getfeeds(){
$stmt = $this->con->prepare("select id,title,status,profilepic,created_at,url from news");
$stmt->execute();
$result = $stmt->get_result();
$row = array();
while ($r = $result->fetch_assoc()) {
$row =$r;
$nrow['news'] = array($row);
$json = str_replace("\\/", "/",json_encode($nrow,JSON_PRETTY_PRINT));
echo'<pre>';
return $json;
}
feed.php
<?php
session_start();
require_once 'include/DB_Functions.php';
$db = new DB_Functions();
$feeds= $db->getfeeds();
print_r($feeds);
?>
輸出是
{
"news": [
{
"id": 1,
"title": "test",
"status": "this is content",
"profilepic": "0",
"created_at": "2016-09-05 12:11:17",
"url": "0"
}
]
}
但輸出應該來像這樣兩行
{
"news": [
{
"id": "1",
"title": "test",
"status": "this is content",
"profilepic": "0",
"created_at": "2016-09-05 12:11:17",
"url": "0"
}
]
}
{
"news": [
{
"id": "2",
"title": "JCECE",
"status": "JCECE 2016 will be conducted on June 5, 2016 by JCECE Board, which is the exam conducting authority for the engineering entrance examination.

你有RETURN ** while循環**這是否給你一個線索 – RiggsFolly
良好的代碼縮進會作出明顯的裏面,因爲它沒有當我整理了一下說一段代碼。 – RiggsFolly
@ riggsfolly我曾嘗試返回,而循環其給予空值 –
