I get back the data from DB with php, and I get it back as follows so I want to modify it.
This what I tried:
$result = $db->run("SELECT * FROM.....")->fetchAll();
foreach($result as $key => $val) {
$result[$key] = $result[$key]['id'];
}
I want to change the key ( 0, 1) to the id values (5, 6) Change this:
{
"0": {
"id": 5,
"date_created": "2021-08-18 03:35:31",
"status": 1
},
"1": {
"id": 6,
"date_created": "2021-08-18 03:35:55",
"status": 1
}
}
To this:
{
"5": {
"id": 5,
"date_created": "2021-08-18 03:35:31",
"status": 1
},
"6": {
"id": 6,
"date_created": "2021-08-18 03:35:55",
"status": 1
}
}
try this
$newResult = [];
foreach($result as $key => $val) {
$newResult[$val['id']] = $val;
}
print_r($newResult);

I have question, is it possible not to duplicate the array object by looping on it? Right now I used laravel as my backend
I have here my response which is the exchange object duplicate itself.
[
{
"exchange": {
"id": 1,
"branch": "BB1",
"old_check_no": "0001",
"cash": "250000",
"bank_deposit": "1000000",
"offset": "250000",
"amount": "10000",
"over_under": null,
"checkDate": "2021-09-11",
"remarks": "1",
"date_closed": "2021-09-11"
},
"exchange_list": {
"exchange_id": 1,
"new_check_no": "001",
"new_check_bank": "bank",
"new_check_branch": "Lagros"
}
},
{
"exchange": {
"id": 1,
"branch": "BB1",
"old_check_no": "0001",
"cash": "250000",
"bank_deposit": "1000000",
"offset": "250000",
"amount": "10000",
"over_under": null,
"checkDate": "2021-09-11",
"remarks": "1",
"date_closed": "2021-09-11"
},
"exchange_list": {
"exchange_id": 1,
"new_check_no": "002",
"new_check_bank": "bank",
"new_check_branch": "Lagros"
}
},
]
Now my goal is to push the exchange without duplication:
[
{
"exchange": {
"id": 1,
"branch": "BB1",
"old_check_no": "0001",
"cash": "250000",
"bank_deposit": "1000000",
"offset": "250000",
"amount": "10000",
"over_under": null,
"checkDate": "2021-09-11",
"remarks": "1",
"date_closed": "2021-09-11"
},
"exchange_list": {
"exchange_id": 1,
"new_check_no": "001",
"new_check_bank": "bank",
"new_check_branch": "Lagros"
},
"exchange_list": {
"exchange_id": 1,
"new_check_no": "002",
"new_check_bank": "bank",
"new_check_branch": "Lagros"
}
}
]
Here is what my foreach loop like and how i push the array object.
$myArray = [];
foreach($exchange_check as $primary_array) {
foreach($exchange_lists as $second_array) {
if($second_array->exchange_id == $primary_array->id) {
array_push($myArray, (object)[
'exchange' => $primary_array,
'exchange_list' => $second_array,
]);
}
}
}
Thanks
You should add exchange data to array only once in first loop:
$myArray = [];
foreach($exchange_check as $primary_array) {
$idx = array_push($myArray, ['exchange' => $primary_array]);
foreach($exchange_lists as $second_array) {
if($second_array->exchange_id == $primary_array->id) {
//array_push() returns the new number of elements in the array,
//to get currently added array element we should subtract 1 from this number
$myArray[$idx-1]['exchange_list'][] = $second_array;
}
}
}
And in second loop add only exchange_list data to array.
I tried to parse a JSON using PHP from url. I need a list of item that have no children - means children field should be empty array and parent_id shouldn't be 0 - means not be parents.
JSON:
{
"body": {
"data": [
{
"id": 1,
"name": "car",
"parent_id": "0",
"children": [
{
"id": 2,
"name": "bmw",
"parent_id": "1",
"children": [
{
"id": 4,
"name": "bmw i8",
"parent_id": "2",
"children": []
}
]
},
{
"id": 3,
"name": "mustang",
"parent_id": "1",
"children": []
}
]
},
{
"id": 5,
"name": "clothes",
"parent_id": "0",
"children": []
},
{
"id": 6,
"name": "mobile",
"parent_id": "0",
"children": [
{
"id": 7,
"name": "apple",
"parent_id": "6",
"children": [
{
"id": 9,
"name": "Iphone 12 pro",
"parent_id": "7",
"children": []
},
{
"id": 10,
"name": "Iphone 11",
"parent_id": "7",
"children": []
}
]
},
{
"id": 8,
"name": "Xiaomi",
"parent_id": "6",
"children": []
}
]
}
]
}
}
Output Expected:
[4,3,9,10,8]
This is my php code that i tried and doesn't work.
$CategoryUrl = file_get_contents(self::CATEGORY_URL,true);
$array = json_decode($CategoryUrl,true);
$list = array();
foreach( $array['body']['data'] as $value ){
if (($value['parent_id'] != 0) && empty($value['children'])) {
foreach( $value['children'] as $val ){
$list[] = $val;
}
}
}
print_r($list);
It is indeed a little tricky to keep track of parent ID values and children call using array_walk_recursive as it jumps directly to its children. However, this can be still accomplished with your own recursive version like below. Keep checking with parent_id and children count. If both constraints satisfy, add them to $result, else keep calling children recursively.
<?php
$str = '{"body":{"data":[{"id":1,"name":"car","parent_id":"0","children":[{"id":2,"name":"bmw","parent_id":"1","children":[{"id":4,"name":"bmw i8","parent_id":"2","children":[]}]},{"id":3,"name":"mustang","parent_id":"1","children":[]}]},{"id":5,"name":"clothes","parent_id":"0","children":[]},{"id":6,"name":"mobile","parent_id":"0","children":[{"id":7,"name":"apple","parent_id":"6","children":[{"id":9,"name":"Iphone 12 pro","parent_id":"7","children":[]},{"id":10,"name":"Iphone 11","parent_id":"7","children":[]}]},{"id":8,"name":"Xiaomi","parent_id":"6","children":[]}]}]}}';
$data = json_decode($str,true);
$result = [];
function walkRecursive($data,&$result){
foreach($data as $entry){
if($entry['parent_id'] != 0 && count($entry['children']) == 0){
$result[] = $entry['id'];
}else{
walkRecursive($entry['children'],$result);
}
}
}
walkRecursive($data['body']['data'],$result);
print_r($result);
We can solve this problem by function call recursive algorithm,
hope it clear for you
$CategoryUrl = file_get_contents(self::CATEGORY_URL,true);
$array = json_decode($CategoryUrl, true);
$items = $array['body']['data'];
$list = [];
findParentIds(items, $list);
// doSomething
print_r($list);
/**
* passe by ref (list)
* #param array $children
* #param $list
*/
function findParentIds(array $children, & $list)
{
foreach ($children as $child) {
// use case 1: has no children and parent_id is 0 , just continue
if (empty($child['children']) && $child['parent_id'] == "0") {
continue;
}
// use case 2: has no children and parent_id is 0 , it's parent item
if (empty($child['children']) && $child['parent_id'] != "0") {
array_push($list, $child['id']);
}
// has children and parent_id is not 0 , recall function to treat use case 1 and 2 ..
findParentIds($child['children'], $list);
}
}
Hi I'am trying to get data Array and looping with For. So I have array called 'color' and I want loop the Array with For. But I have some trouble in the result. I've been tried change the array and in foreach but I got no idea how to get result like what I want.
The Result :
"data": [
{
"title": "get data users",
"function_name": "selectDataUser",
"function_drop": "selectDataUser",
"type_of_chart": "Pie",
"embed": null,
"created_at": "2019-06-15 03:26:09.000",
"updated_at": null,
"data_chart": [
{
"name": "Administrator",
"total": "100",
"color": "0xFF888888" //color cannot be the same
},
{
"name": "Staff",
"total": "100",
"color": "0xFF888888" //the color must be different
},
{
"name": "Super Administrator",
"total": "1",
"color": "0xFF888888" //this is not result what I want.
}
],
}
]
I want response like this:
"data": [
{
"title": "get data users",
"function_name": "selectDataUser",
"function_drop": "selectDataUser",
"type_of_chart": "Pie",
"embed": null,
"created_at": "2019-06-15 03:26:09.000",
"updated_at": null,
"data_chart": [
{
"name": "Administrator",
"total": "100",
"color": "0xFF000000" //all this color different
},
{
"name": "Staff",
"total": "100",
"color": "0xFF444444" //the color different
},
{
"name": "Super Administrator",
"total": "1",
"color": "0xFF888888" //this is result what I want.
}
],
}
]
This my code :
public function index(Request $request)
{
try {
$query = $this->dashboard->with('rolesDashboard','userDashboard')
->orderBy('id')
->get();
$data=[];
foreach ($query as $key) {
$data_chart = DB::select($key->function_name); //call store procedure from SQL Server
$color = array(
"0xFF000000" ,
"0xFF444444" ,
"0xFF888888" ,
"0xFFCCCCCC",
"0xFFFFFFFF",
"0xFFFF0000" ,
"0xFF00FF00" ,
); // this is array color
for ($i=0; $i < count($data_chart) ; $i++) {
$set = $color[$i]; //Get data array color
}
foreach($data_chart as $row){
$row->color = $set;
}
$data[] = [
'title' => $key->title,
'function_name' => $key->function_name,
'created_at' => $key->created_at,
'updated_at' => $key->updated_at,
'data_chart' => $data_chart, //return data_chart and color
];
}
return response()->default(200, trans('messages.success.get-data'),$data);
} catch (Exception $e) {
return response()->default(400, $e->getMessage());
}
}
$set is array, cannot be assigned as a string. My advice is changing below code:
for ($i=0; $i < count($data_chart) ; $i++) {
$set = $color[$i]; //Get data array color
}
foreach($data_chart as $row){
$row->color = $set;
}
to
$i=0;
foreach($data_chart as $row){
$row->color = $color[$i];
$i++;
}
but if your $data_chart count is more than $color count it will return error, for better handling use code below:
$i=0;
foreach($data_chart as $row){
if(isset($color[$i])){
$row->color = $color[$i];
$i++; }
else{
$i=0;
}
}
I have a 3 tables product, category, attributes. In attributes table there is parent_id used for sub-attributes in a same table.Using loop I get a data.
My code :
$productDetails = Product::with('categories')->get();
foreach ($productDetails as $key => $value) {
foreach ($value->categories as $key => $value) {
$attributes = Attribute::where('product_id',$value->product_id)->where('category_id',$value->id)->where('parent_id',Null)->get();
$value->Attributes = $attributes;
foreach ($attributes as $key => $value) {
$subAttributes = Attribute::where('parent_id', $value->id)->get();
$value->subAttributes = $subAttributes;
}
}
}
Output :
{
"productDetails": [
{
"id": 1,
"title": "Small Size Diamond",
"icon": null,
"status": "Active",
"categories": [
{
"id": 1,
"product_id": 1,
"title": "Sieve Size",
"status": "Active",
"sort_order": 1,
"Attributes": [
{
"id": 1,
"product_id": 1,
"category_id": 1,
"parent_id": null,
"title": "- 2.0",
"status": "Active",
"sort_order": 1,
"subAttributes": [
[
{
"id": 9,
"product_id": 1,
"category_id": 1,
"parent_id": 1, // Attributes table ID
"title": "+ 0000 - 000",
"status": "Active",
"sort_order": 1
},
{
"id": 10,
"product_id": 1,
"category_id": 1,
"parent_id": 1, // Attributes table ID
"title": "+ 000 - 00",
"status": "Active",
"sort_order": 2
}
]
]
}
]
}
]
}
]}
The problem is in first product I gt completed response but in other prodcts in loop I do not get subAttributes data. How can i do this?
Simple, please do not use same variable name in all foreach loop,
Your code should like following
$productDetails = Product::with('categories')->get();
foreach ($productDetails as $pro_key => $pro_value) {
foreach ($pro_value->categories as $cat_key => $cat_value) {
$attributes = Attribute::where('product_id',$cat_value->product_id)->where('category_id',$cat_value->id)->where('parent_id',Null)->get();
$cat_value->Attributes = $attributes;
foreach ($attributes as $att_key => $att_value) {
$subAttributes = Attribute::where('parent_id', $att_value->id)->get();
$att_value->subAttributes = $subAttributes;
}
}
}
I have an array structured like so:
data: [
{
"category": "CAT555",
"products": {
"productID": 12345,
"sku": 3333
},
},
{
"category": "CAT1111",
"products": {
"productID: 12441,
"sku": 9999
},
}
]
If I have a new product I'd like to add to the CAT555 category? How would I do that?
Currently have this:
$key = array_search($categoryID, array_column($categories, 'categoryID'));
if ($key != false){
$categories[$key]['products'][] = [
'productID': '91232',
'sku': '52433'
];
But the result ends up looking like this:
data: [
{
"category": "CAT555",
"products":
"0": {
"productID": 12345,
"sku": 3333
}
},
{
"productID": 12345,
"sku": 3333
},
},
{
"category": "CAT1111",
"products": {
"productID: 12441,
"sku": 9999
},
}
]
Use the following approach with array_merge function:
$new_product = [
'productID' => '91232',
'sku' => '52433'
];
$search_key = 'CAT555';
foreach ($categories as $k => &$v) {
if ($v['category'] == $search_key) { // if the needed key is found
(isset($v['products'][0]))?
$v['products'].push($new_product)
: $v['products'] = array_merge([$v['products']], [$new_product]);
}
}
print_r($categories);
