I have a json data generated with the following php code
$index = array();
foreach($rows as $row)
{
$row['data'] []= (object) [];
$index[$row['cat_id']] = $row;
}
// build the tree
foreach($index as $id => &$row)
{
if ($id === 0) continue;
$parent = $row['parent'];
$index [$parent]['children'][] = &$row;
}
unset($row);
// obtain root node
$index = $index[0]['children'][0];
$json_data = json_encode($index, JSON_PRETTY_PRINT);
which produces the following json
{
"cat_id": "1",
"id": "RT",
"name": "root",
"parent": "0",
"url": "www.test.com",
"data": [
{}
],
"children": [
{
"cat_id": "4",
"id": "CI.001",
"name": "Test2",
"parent": "2",
"url": "www.test.com",
"data": [
{}
]
}
what i want is the output to be like this
var something = [{
"cat_id": "1",
"id": "RT",
"name": "root",
"parent": "0",
"url": "www.test.com",
"data": [
{}
],
"children": [
{
"cat_id": "4",
"id": "CI.001",
"name": "Test2",
"parent": "2",
"url": "www.test.com",
"data": [
{}
]
}];
I have looked through the web with some suggesting that it is not json but php array i'm new to json. How can I solve this ?
Here is is my solution at the moment.
ob_start();
echo "var javascript_array = [". $json_data . "];\n";
$content = ob_get_contents();
file_put_contents('../core/json/tree.js', $content);
Any suggestions and improvements will be appreciated.

i got this now:
i made this update.. but still not the needed result.
this is my php code...
$result = [];
foreach ($data as $item) {
$firstLetter = substr($item['name'], 0, 1);
$result[] = [
'title' => $firstLetter = ctype_alnum($firstLetter) ? $firstLetter : '#',
'data' => $item
];
}
foreach ($result as $key => $item) {
$arr[$item['title']][$key] = $item;
}
and this is the result.
{
"A": [
{
"title": "A",
"data": {
"brand_id": "312",
"brand_name": "Adidsa"
}
},
{
"title": "A",
"data": {
"id": "314",
"name": "Adio"
}
},
still can't find make the needed response..
This is not perfomance optimized, but shows a simple solution.
Collect all data grouped by title, then reformat the array to your expected result.
$array = json_decode($json, true);
$collect = [];
foreach($array as $item) {
$collect[$item['title']][] = $item['data'];
}
ksort($collect);
$titles = [];
foreach($collect as $title => $data) {
$names = array_column($data, 'name');
array_multisort($names, SORT_ASC, SORT_STRING, $data);
$titles[] = ['title' => $title, 'data' => $data];
}
echo json_encode($titles, JSON_PRETTY_PRINT); results in
[
{
"title": "A",
"data": [
{
"id": "317",
"name": "Aesethetica"
},
{
"id": "318",
"name": "Astonos"
}
]
},
{
"title": "B",
"data": [
{
"id": "321",
"name": "Bioderma"
},
{
"id": "320",
"name": "Bourjois"
}
]
}
]
I'm retrieving data from a database and pushing it to arrays then use json_encode() to output in json format. I have ended up having the data in this format.
[
{
"category_id": "1",
"category_name": "Construction Materials"
},
{
"items": [
{
"id": "1",
"item_name": "Wire Mesh",
"price": "459",
"image_url": null
},
{
"id": "2",
"item_name": "Cement",
"price": "700",
"image_url": null
},
{
"id": "3",
"item_name": "Barbed Wire",
"price": "3000",
"image_url": null
},
{
"id": "4",
"item_name": "Iron sheet",
"price": "200",
"image_url": null
}
]
},
{
"category_id": "2",
"category_name": "Plumbing"
},
Here is what I want to achieve:
[
{
"category_id": "1",
"category_name": "Construction Materials"
"items": [
{
"id": "1",
"item_name": "Wire Mesh",
"price": "459",
"image_url": null
},
{
"id": "2",
"item_name": "Cement",
"price": "40",
"image_url": null
},
{
"id": "3",
"item_name": "Barbed Wire",
"price": "3000",
"image_url": null
},
{
"id": "4",
"item_name": "Iron sheet",
"price": "200",
"image_url": null
}
]
},
{
"category_id": "2",
"category_name": "Plumbing"
},
How can I achive this in php. Is it possible to edit the contents of the main array? how can I add "items" after "category_name"
Regards..
$array = json_decode($yourJson);
$arrayLength = count($array);
$finalArray = [];
for ($i=0; $i < $arrayLength; $i+=2) {
$finalArray[] = $array[$i] + $array[$i + 1];
}
$backToJson = json_encode($finalArray);
Alternative to Mattijs's answer.
function get_first_property($object) {
$properties = array_keys(get_object_vars($object));
return reset($properties);
}
function object_merge($object1, $object2) {
return (object) array_merge((array) $object1, (array) $object2);
}
// loop through each of the array objects
$previous_first_property = null;
foreach ($array as $i => $object) {
$first_property = get_first_property($object);
// merge if the 1st property is "items", and the previous 1st was "category_id"
if ($first_property == "items" && $previous_first_property == "category_id") {
$array[$i - 1] = object_merge($array[$i - 1], $array[$i]);
unset($array[$i]);
}
$previous_first_property = $first_property;
}
This is my PHP code for json output:
$sql="SELECT id,name FROM languages ORDER BY id";
$result=mysqli_query($conn,$sql);
// Fetch all
$result = mysqli_fetch_all($result,MYSQLI_ASSOC);
$out_put = json_encode($result);
echo $out_put;
This is the json output of the above php code:
{
"0": {
"id": "1",
"name": "English"
},
"1": {
"id": "2",
"name": "Kanada"
},
"2": {
"id": "3",
"name": "Hindi"
},
"3": {
"id": "4",
"name": "Telugu"
}
}
But I want output like this:
{
"Responsecode":200,
"Message":"Sucess",
"languagelist": [
{
"id": "1",
"name": "English"
},
{
"id": "2",
"name": "Kannada"
},
{
"id": "3",
"name": "Hindi"
},
{
"id": "4",
"name": "Telugu"
}
]
}
I am trying to create API and I am new in it. Please help. Thank you in advance.
Just write
$out_put = json_encode([
"Responsecode" => 200,
"Message" => "Sucess",
"languagelist" => $result
]);
You can do it by this way:
$output['Responsecode'] = 200;
$output['Message'] = "Sucess";
$output['languagelist'] = $result;
$out_put = json_encode($output);
I'm trying to make a json that looks like this:
{
"data": {
"error_message": "",
"data": {
"person": [
[
{
"name": "teset1",
"image": "http://test.co.il/test/icons/billadress.png"
},
{
"name": "test2",
"image": "http://test.co.il/test/icons/email.png"
},
{
"name": "test3",
"image": "http://test.co.il/test/icons/homeicon.png"
}
],
[
{
"name": "a",
"image": "http://test.co.il/shay/keykit/icons/billadress.png"
},
{
"name": "b",
"image": "http://test.co.il/shay/keykit/icons/email.png"
},
{
"name": "c",
"image": "http://dvns.co.il/shay/keykit/icons/homeicon.png"
}
],
[
{
"name": "a",
"image": "http://test.co.il/test/icons/billadress.png"
},
{

"image": "http://test.co.il/test/icons/email.png"
},
{
"name": "c",
"image": "http://dvns.co.il/test/icons/homeicon.png"
}
],
]
}
},
}
This is the code i'm using after i'm getting the name & image from the mysql query:
$response = $this->_db->query($query)->result_array();
$icons_results = array();
$obj = new stdclass();
foreach ($response as $key => $response) {
$icons_model = new icons_model();
$icons_model->init($response);
$obj->families[] = $icons_model;
}
return $obj;
SO .. this is what i'm getting:
{
"data": {
"families": [
{
"id": "1",
"name": "a",
"image_url": "http://test.co.il/shay/keykit/icons/billadress.png"
},
{
"id": "2",
"name": "b",
"image_url": "http://test.co.il/shay/keykit/icons/email.png"
},
{
"id": "3",
"name": "c",
"image_url": "http://test.co.il/test/icons/homeicon.png"
},
{
"id": "6",
"name": "f",
"image_url": "http://test.co.il/test/icons/homeicon.png"
},
{
"id": "4",
"name": "d",
"image_url": "http://test.co.il/test/icons/billadress.png"
},
{
"id": "5",
"name": "e",
"image_url": "http://test.co.il/test/icons/billadres2323s.png"
},
and do on.
How to i make that every three object will be in a group? (like the first example)
Try this:
foreach ($response as $key => $response) {
$icons_model = new icons_model();
$icons_model->init($response);
$obj->families[(int)($key / 3)][] = $icons_model;
}
I have:
$all = array(
array('id'=>1, 'cat'=>'Main','type'=>'Name0'),
array('id'=>2, 'cat'=>'Main','type'=>'Name1'),
array('id'=>3, 'cat'=>'Main','type'=>'Name3'),
array('id'=>4, 'cat'=>'Main','type'=>'Name4'),
array('id'=>5, 'cat'=>'Secondary','type'=>'Name5'),
array('id'=>6, 'cat'=>'Secondary','type'=>'Name6'),
array('id'=>7, 'cat'=>'Secondary','type'=>'Name7'),
array('id'=>8, 'cat'=>'Other','type'=>'Name8'),
array('id'=>9, 'cat'=>'Other','type'=>'Name9'),
array('id'=>10, 'cat'=>'Other','type'=>'Name10'),
array('id'=>11, 'cat'=>'Other','type'=>'Name11'),
);
$result = array();
foreach($all as $array){
$result[$array['cat']][] = array('id'=>$array['id'],'type'=>$array['type']);
}
$json_type = json_encode($result);
Which returns:
{"Main":[{"id":"1","type":"name1"},{"id":"2","type":"name2"},{"id":"3","type":"name3"},{"id":"4","type":"name4"}],"Secondary":[{"id":"5","type":"name5"},{"id":"6","type":"name6"},{"id":"7","type":"name7"}],"Other":[{"id":"8","type":"name8"},{"id":"9","type":"name9"},{"id":"10","type":"name10"},{"id":"11","type":"name11"}]}
But I need it to return as:
[
{
"text": "Main",
"children": [
{
"id": "1",
"text": "name1"
},
{
"id": "2",
"text": "name2"
},
{
"id": "3",
"text": "name3"
},
{
"id": "4",
"text": "name4"
}
]
},
{
"text": "Secondary",
"children": [
{
"id": "5",
"text": "name5"
},
{
"id": "6",
"text": "name6"
},
{
"id": "7",
"text": "name7"
}
]
},
{
"text": "Other",
"children": [
{
"id": "8",
"text": "name8"
},
{
"id": "9",
"text": "name9"
},
{
"id": "10",
"text": "name10"
},
{
"id": "11",
"text": "name11"
}
]
}
]
To work with the select2 JQuery plugin, I'm working with.
the 'children' name doesn't matter, I think that's just a placeholder so it gets parsed correctly. I'm not sure how I would go about it, I've been trying str_replace() but even that hasn't been working out so great.
I would to it in 2 loops. The first one to group results by category, the 2nd one to format it to fit your needs:
$temp = array();
foreach($all as $array){
if (!isset($temp[$array['cat']])) {
$temp[$array['cat']] = array();
}
$temp[$array['cat']][] = array('id'=>$array['id'], 'type'=>$array['type']);
}
$result = array();
foreach ($temp as $key=>$value) {
$result[] = array('text'=>$key, 'children'=>$value);
}
echo json_encode($result);
This produces the following output:
[{"text":"Main","children":[{"id":1,"type":"Name0"},{"id":2,"type":"Name1"},{"id":3,"type":"Name3"},{"id":4,"type":"Name4"}]},{"text":"Secondary","children":[{"id":5,"type":"Name5"},{"id":6,"type":"Name6"},{"id":7,"type":"Name7"}]},{"text":"Other","children":[{"id":8,"type":"Name8"},{"id":9,"type":"Name9"},{"id":10,"type":"Name10"},{"id":11,"type":"Name11"}]}]
