我想從我的查詢中創建json數據。但我無法得到我的JSON數據,因爲我預計。請幫忙。這是我試過的代碼。 (它看起來像你的職位主要是代碼,請添加更多的細節是否足夠?)從活動記錄中獲取json數據
<?php
$this->db->select('campus.*, class.*');
$this->db->from('campus');
$this->db->join('class', 'campus.id = class.campus_id');
$campus_info = $this->db->get()->result_array();
foreach ($campus_info as $row) {
$var[]['id'] = $row['id'];
$var[]['campus_name'] = $row['campus_name'];
$var[]['class_id'] = $row['class_id'];
$var[]['class_name'] = $row['name'];
}
$json_data = json_encode($var, JSON_PRETTY_PRINT);
echo '<pre>';
echo $json_data;
echo '</pre>';
exit();
我的查詢結果是
Array
(
[0] => Array
(
[id] => 4
[campus_name] => Test Campus Name
[institute_name] => Test Institute Name 1
[class_id] => 11
[name] => STD - VIII
[campus_id] => 4
[name_numeric] => 8
[teacher_id] => 6
)
[1] => Array
(
[id] => 4
[campus_name] => Test Campus Name
[institute_name] => Test Institute Name 1
[class_id] => 15
[name] => A' Level
[campus_id] => 4
[name_numeric] => 12
[teacher_id] => 6
)
想讓它JSON像
[{
"id": "7",
"campus_name": "Azimpur",
"class_id": "9",
"class_name": "STD - VI"
}
{
"id": "8",
"campus_name": "Azimpur",
"class_id": "10",
"class_name": "STD - VII"
}]
但是獲得
[
{
"id": "4"
},
{
"campus_name": "Test Campus Name"
},
{
"class_id": "11"
},
{
"class_name": "STD - VIII"
},
{
"id": "4"
},
{
"campus_name": "Test Campus Name"
},
非常感謝,它的工作原理。 –
