Foreach gagal membina tatasusunan dalam php

Question

Kod:

<?php
$arr=array();
foreach($data as $row){
    $arr['name']=$row->user->username;
    $arr['time']=$row->user->time;
};
echo json_encode($arr);
?>

Mengapa output json hanya mempunyai satu bahagian kandungan?

Answer 1

Sayang, baca manual lebih banyak dan kuasai tatabahasa.

<?php
$arr=array();
foreach($data as $row){
    $t['name']=$row->user->username;
    $t['time']=$row->user->time;
    $arr[] = $t;
};
echo json_encode($arr);
?>

Answer 2

<?php
$arr=array();
foreach($data as $key=>$row){
    $arr[$key]['name']=$row->user->username;
    $arr[$key]['time']=$row->user->time;
};
echo json_encode($arr);
?>
