So I have an array stored in a variable called $data that looks like this:
["data"]=>
["rows"]=>
array(30) {
[0]=>
array(3) {
[0]=>
string(10) "2016-08-15"
[1]=>
int(0)
[2]=>
int(0)
}
[1]=>
array(3) {
[0]=>
string(10) "2016-08-16"
[1]=>
int(0)
[2]=>
int(0)
}
[2]=>
array(3) {
[0]=>
string(10) "2016-08-17"
[1]=>
int(0)
[2]=>
int(0)
}
[3]=>
array(3) {
[0]=>
string(10) "2016-08-18"
[1]=>
int(0)
[2]=>
int(0)
}
By using the following function I take the values from the array:
$subscribersGained = [];
foreach ($data->data->rows as $obj) {
if (isset($obj[1])) {
// add the element to the beginning of the array
array_unshift($subscribersGained, $obj[1]);
}
if(count($subscribersGained) >= 30) {
break;
}
}
$gained = array_map( create_function('$value', 'return (int)$value;'),
$subscribersGained);
echo json_encode($gained);
And store them into a json_string that looks like this:
[0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]
What I need to do is that I have to make the non 0 number be negative. So in this case I want to have -1 not 1. Any ideas how to make that happen? Thank you for your time!
Well, the most primitive way to do it that I figure out it is:
foreach($array as $key => $number) {
$array[$key] = 0 - $number;
}
$gained = array(0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0);
$gained = array_map(function($el) { return 0-$el; }, $gained);
print_r($gained);

I have an array and I iterate through its first 7 values with this function:
function clicksLast7Days($data)
{
$path = $data->data->data->clicks;
$num_loops = 0;
foreach ($path as $key => $item){
$num_loops++;
if($num_loops > 7) break;
if ($key >= 0) {
$array[] = $item->clicks;
}
}
return json_encode($array);
}
The array's structure (if it helps) is:
["data"]=>
object(stdClass)#212 (3) {
["status_code"]=>
int(200)
["data"]=>
object(stdClass)#211 (3) {
["days"]=>
int(30)
["total_clicks"]=>
int(6)
["clicks"]=>
array(30) {
[0]=>
object(stdClass)#215 (2) {
["clicks"]=>
int(0)
["day_start"]=>
int(1466395200)
}
[1]=>
object(stdClass)#216 (2) {
["clicks"]=>
int(0)
["day_start"]=>
int(1466308800)
}
[2]=>
object(stdClass)#217 (2) {
["clicks"]=>
int(0)
["day_start"]=>
int(1466222400)
}
[3]=>
object(stdClass)#218 (2) {
["clicks"]=>
int(0)
["day_start"]=>
int(1466136000)
}
[4]=>
object(stdClass)#219 (2) {
["clicks"]=>
int(0)
["day_start"]=>
int(1466049600)
}
[5]=>
object(stdClass)#220 (2) {
["clicks"]=>
int(0)
["day_start"]=>
int(1465963200)
}
[6]=>
object(stdClass)#221 (2) {
["clicks"]=>
int(0)
["day_start"]=>
int(1465876800)
}
[7]=>
object(stdClass)#222 (2) {
["clicks"]=>
int(0)
["day_start"]=>
int(1465790400)
}
The problem is that by using my function I get an array of elements:
[0,0,0,0,0,0,0]. But what I want is to obtain their sum (which in this case is 0), and not an array, just a number.
$clicksArray = $data->data->data->clicks;
$sum = array_sum(
array_map(
$clicksArray,
function($clickElement) {
return $clickElement->clicks;
}
)
);
What does this mean ?
array_sum will sum all values of a certain array. More information here
array_map will return all elements of an array, after applying a function (so, basically here, we are returning only clicks attribute
I got this array
array(5) {
[0]=>
array(5) {
["id"]=>
int(1411667077)
["nachricht"]=>
string(13) "iiiiiiiiiiiii"
["user"]=>
string(15) "334607943355808"
["datum"]=>
string(16) "25.09.2014 19:44"

["deleted"]=>
string(0) ""
}
}
I want to cut the where the id is 1411701737 so I tryed:
foreach($array as $arr => $sub_arr)
{
if $sub_arr['id'] == 1411701737
{
break;
}
}
I know I need to create a whole new array in the foreach, but isn't there maybe a build in function?
$arr_new = array(); //Define a new array
foreach($arr_old as $a) { //Loop through the old one
if($a['id'] === 1411701737) break; //If the value of id matches, leave the foreach loop
$arr_new[] = $a; //Else, copy this array to the new array
}
print_r($arr_new); //Print the new array
$new = array();
foreach($array as $k) {
if($k['id'] == 1411701737) break;
array_push($new, $k);
}
var_dump($new);
The answer by Mooseman is likely a faster way to do this since it does not rely on a PHP function call to place the array into the new array. However unless you are doing this on a set of arrays that is in the 100k+ it really won't matter.
Im new to json & php and I'm having some issues with json into php string
My json string looks like this
{"status":"OK","cards":
[{"id":100001,"name":"batman","image":11111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T11:37:07Z"},
{"id":100002,"name":"superman","image":111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T12:30:09Z"},
{"id":100003,"name":"catwoman","image":1111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T12:39:42Z"},
{"id":100004,"name":"bane","image":1111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-09-08T12:56:04Z"}
]}
So Far i have created my string
$json_raw = '{"status":"OK","cards": [{"id":100001,"name": .....
Decoded the json
$arr = json_decode($json_raw, TRUE);
I var_dump($arr);
then it returns
array(2) { ["status"]=> string(2) "OK" ["cards"]=> array(4) { [0]=> array(8) { ["id"]=> int(100001) ["name"]=> string(6) "batman" ["image"]=> int(11111) ["size"]=> int(75) ["region_id"]=> int(1) ["locked"]=> bool(false) ["status"]=> string(6) "active" ["created_at"]=> string(20) "2013-08-15T11:37:07Z" } [1]=> array(8) { ["id"]=> int(100002) ["name"]=> string(8) "superman" ["image"]=> int(111111) ["size"]=> int(75) ["region_id"]=> int(1) ["locked"]=> bool(false) ["status"]=> string(6) "active" ["created_at"]=> string(20) "2013-08-15T12:30:09Z" } [2]=> array(8) { ["id"]=> int(100003) ["name"]=> string(8) "catwoman" ["image"]=> int(1111111) ["size"]=> int(75) ["region_id"]=> int(1) ["locked"]=> bool(false) ["status"]=> string(6) "active" ["created_at"]=> string(20) "2013-08-15T12:39:42Z" } [3]=> array(8) { ["id"]=> int(100004) ["name"]=> string(4) "bane" ["image"]=> int(1111111) ["size"]=> int(75) ["region_id"]=> int(1) ["locked"]=> bool(false) ["status"]=> string(6) "active" ["created_at"]=> string(20) "2013-09-08T12:56:04Z" } } }
Now all I want to do is be able to use this data
e.g if name = batman then
I know this is a stupid question but I am struggling :(
Thank in Advance
json_decode() with TRUE as second parameter gives you an associative array. You need to access the correct index to do what you want.
To list the complete associative array with nice formatting, you can do:
echo '<pre>', print_r($arr), '</pre>';
Now, to access the name in your array:
$man = $arr['cards'][0]['name'];
To check if it's Batman (yay!):
if( isset($man) && $man == 'batman' ) {
# code ...
}
For getting the name of all similar names:
$man = $json['cards']['0']['name'];
for ($i=0; $i < count($json['cards']); $i++) {
echo $json['cards'][$i]['name']."\n";
}
See it live!
when you got the array
$arr = json_decode($json_raw, TRUE);
then check if cards key exist
if(array_key_exists('cards', $arr)){
foreach($arr['cards'] as $key=>$val){
echo $key; ///name, id..
echo $val; /// batman,...
if($key == 'name' && $val =='batman'){
//-------do your stuff
}
}
}
Try with:
$cards = $arr['cards'];
foreach($cards as $card) {
if($card['name'] == 'batman') echo 'Hello batman!';
}
EDIT:
Ok, so this worked for me using code above, try it yourself if you want:
<?php
$json_raw = '{"status":"OK","cards":
[{"id":100001,"name":"batman","image":11111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T11:37:07Z"},
{"id":100002,"name":"superman","image":111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T12:30:09Z"},
{"id":100003,"name":"catwoman","image":1111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T12:39:42Z"},
{"id":100004,"name":"bane","image":1111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-09-08T12:56:04Z"}
]}';
$arr = json_decode($json_raw, TRUE);
$cards = $arr['cards'];
foreach($cards as $card) {
if($card['name'] == 'batman') echo 'Hello batman!';
}

I am trying to do a custom WP_query loop and put the results into an array of associate arrays.. It is not working too well.. I realize the array_push overwrites any arrays that have the same indexes so I have the index increment +1 in the loop so they are not identical..however it still is not working.. My results show correct only on the first index (zero).. Here is my code:
<?php
$permlink='permalink';
$excerpt='exerpt';
$title='title';
$id='id';
$finalarray=array();
for ($i = 0; $i <= 10; $i++) {
$newitem = array(array(
'id'.$i =>$id.$i,
'title'.$i => $title.$i,
'excerpt'.$i => $excerpt.$i,
'permalink'.$i => $permlink.$i
));
array_push($finalarray, $newitem);
}
$count=0;
foreach($finalarray as $item){
echo $count.':'.'<br>';
echo $item[$count]['title'.$count];
echo $item[$count]['id'.$count];
echo $item[$count]['permalink'.$count];
$count++;
}
var_dump($finalarray);
?>
Any my results show :
0:
title0id0permalink01:
2:
3:
4:
5:
6:
7:
8:
9:
10:
array(11) { [0]=> array(1) { [0]=> array(4) { ["id0"]=> string(3) "id0" ["title0"]=> string(6) "title0" ["excerpt0"]=> string(7) "exerpt0" ["permalink0"]=> string(10) "permalink0" } } [1]=> array(1) { [0]=> array(4) { ["id1"]=> string(3) "id1" ["title1"]=> string(6) "title1" ["excerpt1"]=> string(7) "exerpt1" ["permalink1"]=> string(10) "permalink1" } } [2]=> array(1) { [0]=> array(4) { ["id2"]=> string(3) "id2" ["title2"]=> string(6) "title2" ["excerpt2"]=> string(7) "exerpt2" ["permalink2"]=> string(10) "permalink2" } } [3]=> array(1) { [0]=> array(4) { ["id3"]=> string(3) "id3" ["title3"]=> string(6) "title3" ["excerpt3"]=> string(7) "exerpt3" ["permalink3"]=> string(10) "permalink3" } } [4]=> array(1) { [0]=> array(4) { ["id4"]=> string(3) "id4" ["title4"]=> string(6) "title4" ["excerpt4"]=> string(7) "exerpt4" ["permalink4"]=> string(10) "permalink4" } } [5]=> array(1) { [0]=> array(4) { ["id5"]=> string(3) "id5" ["title5"]=> string(6) "title5" ["excerpt5"]=> string(7) "exerpt5" ["permalink5"]=> string(10) "permalink5" } } [6]=> array(1) { [0]=> array(4) { ["id6"]=> string(3) "id6" ["title6"]=> string(6) "title6" ["excerpt6"]=> string(7) "exerpt6" ["permalink6"]=> string(10) "permalink6" } } [7]=> array(1) { [0]=> array(4) { ["id7"]=> string(3) "id7" ["title7"]=> string(6) "title7" ["excerpt7"]=> string(7) "exerpt7" ["permalink7"]=> string(10) "permalink7" } } [8]=> array(1) { [0]=> array(4) { ["id8"]=> string(3) "id8" ["title8"]=> string(6) "title8" ["excerpt8"]=> string(7) "exerpt8" ["permalink8"]=> string(10) "permalink8" } } [9]=> array(1) { [0]=> array(4) { ["id9"]=> string(3) "id9" ["title9"]=> string(6) "title9" ["excerpt9"]=> string(7) "exerpt9" ["permalink9"]=> string(10) "permalink9" } } [10]=> array(1) { [0]=> array(4) { ["id10"]=> string(4) "id10" ["title10"]=> string(7) "title10" ["excerpt10"]=> string(8) "exerpt10" ["permalink10"]=> string(11) "permalink10" } } }
So it looks like the values are in the array, however, only the first index ( zero ) prints correctly.. any suggestions? Also, is there any way i can push an associate array and it not be over written so I dont have to increment the index?
There are a few problems here.
for ($i = 0; $i <= 10; $i++) {
$newitem = array(array(
'id'.$i =>$id.$i,
'title'.$i => $title.$i,
'excerpt'.$i => $excerpt.$i,
'permalink'.$i => $permlink.$i
));
array_push($finalarray, $newitem);
}
You are pushing an array, containing an array, containing 4 elements into $finalarray. There is no need for the outer array(). You can just do $newitem = array(...). array_push appends to end of the array, incrementing the index for you.
Second, in your foreach, your $count variable is not needed at all. When using foreach, $item is the element of the array. No need to look it up by the index.
If you want the index, however, foreach can give it to you.
foreach($finalarray as $count=>$item){
echo $count.':'.'<br>';
echo $item['title'.$count];
echo $item['id'.$count];
echo $item['permalink'.$count];
}
Your original code wasn't working because in each $item there was one array. That array had one item. In each element, the inner aray was always at index 0. Incrementing $count made it so only the 1st element worked, the others didn't because $item[1] didn't exist, it was always $item[0].
for ($i = 0; $i <= 10; $i++) {
$newitem = array(array(
'id'.$i =>$id.$i,
'title'.$i => $title.$i,
'excerpt'.$i => $excerpt.$i,
'permalink'.$i => $permlink.$i
));
$finalarray[] = $newitem;
unset($newitem);
}
Since you don't care about the key of the final array just add it on using $finalarray[]
I have this multidimension array in which I need to update a value. What would be the best way to do so? I tried it with 2 foreach loops but wasn't sure if that was the right approach.
Here is the array in question. I need to update the dollar amount on each sub array (i.e. add 3 to it).
array(6) { ["Ground"]=> array(2) { [0]=> string(3) "USD" [1]=> string(5) "13.63" }
["3 Day Select"]=> array(2) { [0]=> string(3) "USD" [1]=> string(5) "25.26" }
["2nd Day Air"]=> array(2) { [0]=> string(3) "USD" [1]=> string(5) "32.43" }
["Next Day Air Saver"]=> array(2) { [0]=> string(3) "USD" [1]=> string(5) "63.00" }
["Next Day Air"]=> array(2) { [0]=> string(3) "USD" [1]=> string(5) "68.65" }
["Next Day Air Early AM"]=> array(2) { [0]=> string(3) "USD" [1]=> string(6) "103.68" } }
Your foreach loop approach would be correct, unless you expect the data format to change e.g. to have more nested levels. If that were the case, then a recursive function would be best suited.
Also, if the data is expected to remain uniform, you could do this:
foreach( $my_array as $index => $row ){
$my_array[$index][1] += 3;
}
cheers!
foreach ($arr as $k=>$row) {
$arr[$k][1] = floatval($row[1]) + 3;
}
foreach ($array as &$subarray) {
foreach ($subarray as $key=>&$value) {
// do whatever you want with $value
// ...
$value = 'something else'; // example
}
}
Try this:
<?php
foreach($first_array as $first_dem_key)
$first_array[$first_dem_key][1] = $first_array[$first_dem_key][1] + 3;
?>
