I wanna sum all values from my array
for example
{
"data": [
{
"message_count": 14051
},
{
"message_count": 12731
},
{
"message_count": 7867
},
{
"message_count": 6053
},
{
"message_count": 4
}
]
}
and that's my code:
<?php
$messages_count = file_get_contents('baza.html');
$json_a=json_decode($messages_count,true);
$counting_base = ($json_a['data']);
echo array_sum($counting_base);
?>
but I still get '0'. Any ideas?
Thank you very much
This is because your array is two-dimensional. array_sum() requires a one-dimensional array. To make it one-dimensional, loop through the array, and use array_sum(), like so:
$new = array();
foreach ($json_a['data'] as $key => $innerArr) {
$new[] = $innerArr['message_count'];
}
echo array_sum($new); // 40706
Online demo
Try this:
array_sum(array_column($json_a['data'], 'message_count'));
Output: 40706

alternative:
You can do it by a loop:
array_sum()
will not be working since you do not right formated array(1D array).
$sum = 0;
for($i=0; $i<count($counting_base); $i++)
{
$sum += $counting_base['message_count'];
}
echo "Total = ". $sum;

I have an array;
$arr=array(1100,3150,4430,4430,5170,7450,7450,7450,8230);
I want to show them in graph. I want my Y-Axis as my elements of that array and X-Axis as sum up the numbers until that element. (x1,x1+x2,x1+x2+x3,...)
My graph will be;
Y-Axis : 1100,3150,4430,4430,5170,7450,7450,7450,8230
X-Axis : 1100,4250,8680,13110,18280,25730,33180,40630,48860

In this code my X-Axis is (0,1,2,3,4,5,6,7,8) and I don't want that.
I'm sorry if I couldn't explain well, English is not my native language.
The simplest way is just to loop over the values, adding the current array value to the previous output value to create the new output value. You can then convert that into an array of [x => y] values using array_combine:
$arr=array(1100,3150,4430,4430,5170,7450,7450,7450,8230);
$out = array($arr[0]);
for ($i = 1; $i < count($arr); $i++) {
$out[$i] = $out[$i-1] + $arr[$i];
}
$arr = array_combine($out, $arr);
print_r($arr);
Output:
Array (
[1100] => 1100
[4250] => 3150
[8680] => 4430
[13110] => 4430
[18280] => 5170
[25730] => 7450
[33180] => 7450
[40630] => 7450
[48860] => 8230
)
Demo on 3v4l.org
to get that one array into 2 arrays of graph co-ordinates, you can do this:
$x = array();
$y = array();
$running_total = 0;
for($i = 0; $i < count($arr); $i++){
$y[$i] = $arr[$i];
$running_total += $arr[$i];
$x[$i] = $running_total;
}
This will give you two arrays; array $x that contains a list of your X-coordinates, and $y, that gives you a list of your Y-coordinates; and you will still have access to your original $arr array, should you need to do further calculations on it. Based on your question, I think that will get you what you need.
However, if you are saying you want 1 array where the X co-ordinates are the array indexes, and the value is the array value itself, for example $y[3150] = 4250, then that is impossible; because you have duplicates in your original list, you cannot use those values as array indexes without ending up overwriting them.
(At least, not without making each array value an array itself, but that is taking things an order of magnitude above where is probably necessary)
Calculating the running total and storing the data as key-value pairs can be achieved with a foreach() and zero function calls.
Although perhaps a little unorthodox, it is valid syntax to use the "addition assignment" operator as the key of the output array. This updates the $previous value and supplies the calculated value as the key.
Code: (Demo)
$arr = [1100,3150,4430,4430,5170,7450,7450,7450,8230];
$result = [];
$previous = 0;
foreach ($arr as $value) {
$result[$previous += $value] = $value;
}
var_export($result);
// same result as #Nick's answer
I have been struggling with this for quite some time. I have two arrays, which I need to combine.
This is my input:
{
"array_one": {
"mrnreference": [
{
"key_0": "18DK00310020B11A84"
},
{
"key_0": "18DK00310020B11B40"
}
]
},
"array_two": {
"shipperreference": [
{
"key_0": "1861575"
},
{
"key_0": "1861549"
}
]
}
}
Now the structure is, that each item in each array follows each other. So, the result should be something like:
{
"result": [
{
"mrn" : "18DK00310020B11A84",
"shipper" : "1861575"
},
{
"mrn" : "18DK00310020B11B40",
"shipper" : "1861549"
}
]
}
However I simply cannot figure out how to do this.
I have tried to merge the two original arrays:
//Input
$array_one = $request->array_one;
$array_two = $request->array_two;
//Merge the two received arrays
$final = array_merge_recursive($array_one, $array_two);
However, this just removes array_one and array_two, but the array is still split up.
How can I combine above array, so it will have below format:
{
"mrn" : "18DK00310020B11B40",
"shipper" : "1861549"
}
You can do this with some custom code:
$array_one = $request->array_one;
$array_two = $request->array_two;
$final = array_map(function ($value, $key) use ($array_two) {
foreach ($value as $k => $v) {
return [
"mrn" => $v,
"shipper" => array_get($array_two, "shipperreference.$key.$k")
];
}
}, array_get($array_one, 'mrnreference'), array_keys(array_get($array_one, 'mrnreference')));
A very quick solution to this would be just to iterate through a for loop.
for($i = 0; $i < count($array_one); $i++){
$final[$i]["mrn"] = $array_one["mrnreference"][$i]; // Mrn key equals array one value
$final[$i]["shipping"] = $array_two["shipperreference"][$i]; // Shipping key equals array two value
}
However, this has a small caveat that it could lead to an error, if $array_one and $array_two are not the same size.
First of all array_map can be used to get the values and then in simple for loop you can combine them. Notice that the size of mrnreference and shipperreference must be the same otherwise it will pop notice
$json = '
{
"array_one": {
"mrnreference": [
{
"key_0": "18DK00310020B11A84"
},
{
"key_0": "18DK00310020B11B40"
}
]
},
"array_two": {
"shipperreference": [
{
"key_0": "1861575"
},
{
"key_0": "1861549"
}
]
}
}
';
$arr = json_decode($json, true);
$ref = array_map(function($e){return $e['key_0'];}, $arr['array_one']['mrnreference']);
$ship = array_map(function($e){return $e['key_0'];}, $arr['array_two']['shipperreference']);
$output = array();
for ($i = 0, $cnt = count($ref); $i < $cnt ; ++$i) {
$output[] = [
'mrn' => $ref[$i],
'shipper' => $ship[$i],
];
}
echo json_encode(['result' => $output]);
Im studying in array, and I was wondering How can I add key to this kind of array?
{
"items":[
{
"count":"1",
"id":123,
"description":"Bag",
"price":11
},
{
"count":1,
"id":1234,
"description":"10% Discount",
"price":-1.1
}
],
"total":9.9,
"discount_total":9.9
}
because I needed convert the array to have a key base on the id inside the array.
{
"items":{
"123":{
"count":"1",
"cart_id":123,
"description":"Bag",
"price":11
},
"1234":{
"count":1,
"cart_id":1234,
"description":"10% Discount",
"price":-1.1
}
},
"total":9.9,
"discount_total":9.9
}
and this is my code
header('Content-Type: application/json');
$cart_array = json_decode('{
"items":[
{
"count":"1",
"cart_id":123,
"plu":"TP16",
"description":"Bag"
},
{
"count":1,
"cart_id":1234,
"plu":"DISCT10",
"description":"10% Discount"
}
],
"total":9.9,
"discount_total":9.9
}');
foreach ($cart_array->items as $item)
{
$construct["cart_id"] = $item->cart_id;
}
I wanted to ask how can I put the id in the array? I cant use $cart_array['id'] = $value, it returns error.
Uncaught Error: Cannot use object of type stdClass as array
I could really use some explanation here
Following code can help you.
<?php
$json = '{
"items":[
{
"count":"1",
"cart_id":123,
"plu":"TP16",
"description":"Small Four Seasons"
},
{
"count":1,
"cart_id":1234,
"plu":"DISCT10",
"description":"10% Discount"
}
],
"total":9.9,
"discount_total":9.9
}';
$data = json_decode($json,TRUE); //json decode
foreach ($data['items'] as $key => $value)
{
$data['items'][$value['cart_id']] = $value;
unset($data['items'][$key]);
}
echo "<pre>";print_r($data);die;
?>
You don't have to loop at all. You can use array_column to make an array associative with one line of code.
$cart_array['items'] = array_column($cart_array['items'], NULL, 'cart_id');
https://3v4l.org/cPD5n
You can use this code in your application to add keys to indexed array.
foreach($obj as $key=>$val){
foreach ($val as $index=>$content){
$data[$content['id']]=$content;
}
}
You can get same output json data as per you want :
$array = json_decode($data,true);
if(isset($array['items']) && count($array['items']) > 0){
foreach($array['items'] as $key => $value){
$value['cart_id'] = $value['id'];
unset($value['id']);
$array['items'][$value['cart_id']] = $value;
unset($array['items'][$key]);
}
}
echo "<pre>";print_r($array);
echo json_encode($array);
In PHP, how do I loop through the following JSON Object's date key, if the date value are the same then merge the time:
[
{
date: "27-06-2017",
time: "1430"
},
{
date: "27-06-2017",
time: "1500"
},
{
date: "28-06-2017",
time: "0930"
},
{
date: "28-06-2017",
time: "0915"
}
]
Result should looks like this:
[
{
date: "27-06-2017",
time: [{"1430","1500"}]
}, {
date: "28-06-2017",
time: [{"0930, 0915"}]
}
]
Should I create an empty array, then the looping through the JSON and recreate a new JSON? Is there any better way or any solution to reference?
Thank you!
This solution is a little overhead, but if you are sure that your data is sequential and sorted, you can use array_count_values and array_map:
$count = array_count_values(array_column($array, 'date'));
$times = array_column($array, 'time');
$grouped = array_map(function ($date, $count) use (&$times) {
return [
'date' => $date,
'time' => array_splice($times, 0, $count)
];
}, array_keys($count), $count);
Here is working demo.
Another Idea to do this is
<?php
$string = '[{"date": "27-06-2017","time": "1430"},{"date": "27-06-2017","time": "1500"},{"date": "28-06-2017","time": "0930"},{"date": "28-06-2017","time": "0915"}]';
$arrs = json_decode($string);
$main = array();
$temp = array();
foreach($arrs as $arr){
if(in_array($arr->date,$temp)){
$main[$arr->date]['time'][] = $arr->time;
}else{
$main[$arr->date]['date'] = $arr->date;
$main[$arr->date]['time'][] = $arr->time;
$temp[] = $arr->date;
}
}
echo json_encode($main);
?>
live demo : https://eval.in/787695
Please try this:
$a = [] // Your input array
$op= [];//output array
foreach($a as $key => $val){
$key = $val['date'];
$op[$key][] = $val['time'];
}
$op2 = [];
foreach($op as $key => $val){
$op2[] = ['date' => $key, 'time' => $val];
}
// create the "final" array
$final = [];
// loop the JSON (assigned to $l)
foreach($l as $o) {
// assign $final[{date}] = to be a new object if it doesn't already exist
if(empty($final[$o->date])) {
$final[$o->date] = (object) ['date' => $o->date, 'time' => [$o->time]];
}
// ... otherwise, if it does exist, just append this time to the array
else {
$final[$o->date]->time[] = $o->time;
}
}
// to get you back to a zero-indexed array
$final = array_values($final);
The "final" array is created with date based indexes initially so that you can determine whether they've been set or not to allow you to manipulate the correct "time" arrays.
They're just removed at the end by dropping $final into array_values() to get the zero-indexed array you're after.
json_encode($final) will give you want you want as a JSON:
[{"date":"27-06-2017","time":["1430","1500"]},{"date":"28-06-2017","time":["0930","0915"]}]
Yet another solution :
$d = [];
$dizi = array_map(function ($value) use (&$d) {
if (array_key_exists($value->date, $d)) {
array_push($d[$value->date]['time'], $value->time);
} else {
$d[$value->date] = [
'date' => $value->date,
'time' => [$value->time]
];
}
}, $array);
echo json_encode(array_values($d));
A server sends me a $_POST request in the following format:
POST {
array1
{
info1,
info2,
info3
},
info4
}
So naturally, I could extract the info# very simply with $_POST['#info'].
But how do I get the the three info's in the array1?
I tried $_POST['array1']['info1'] to no avail.
Thanks!

is the serialized version of the POST
Use index notation:
$_POST['array1'][0]
$_POST['array1'][1]
$_POST['array1'][2]
If you need to iterate over a variable response:
for ($i = 0, $l = count($_POST['array1']); $i < $l; $i++) {
doStuff($_POST['array1'][$i]);
}
This more or less takes this shape in plain PHP:
$post = array();
$post['info'] = '#';
$post['array1'] = array('info1', 'info2', 'info3');
http://codepad.org/1QZVOaw4
So you can see it's really just an array in an array, with numeric indices.
Note, if it's an associative array, you need to use foreach():
foreach ($_POST['array1'] as $key => $val) {
doStuff($key, $val);
}
http://codepad.org/WW7U5qmN
try
$_POST['array1'][0]
$_POST['array1'][1]
$_POST['array1'][2]
You can simply use a foreach loop on the $_POST
foreach($_POST["array1"] as $info)
{
echo $info;
}
or you can access them by their index:
for($i = 0; $i<sizeof($_POST["array1"]); $i++)
{
echo $_POST["array1"][$i];
}
