I have this array structure that contains ids of one tournament players:
array (
0 =>
array (
0 =>
array (
'player' => 7,
'gol' => 1,
),
1 =>
array (
'player' => 9,
'gol' => 1,
),
),
1 =>
array (
0 =>
array (
'player' => 10,
'gol' => 1,
),
1 =>
array (
'player' => 9,
'gol' => 1,
),
),
),
This array have some duplicates ('player'). I would to generate an array that not contains duplicate of players, and the result will be sum of each goal by player, such as:
array(
0 =>
array (
'player' => 7,
'gol' => 1,
),
1 =>
array (
'player' => 9,
'gol' => 2,
),
2 =>
array (
'player' => 10,
'gol' => 1,
),
),
This is my code:
if ($query->have_posts()) {
$players = [];
while ($query->have_posts()) {
$query->the_post();
if (have_rows('field_name', $id)):
while (have_rows('field_name', $id)) : the_row();
$tmp = [];
$player = get_sub_field('player_name', $id);
$tmp['player'] = $player['ID'];
$tmp['gol'] = get_sub_field('player_goal', $id);
array_push($players, $tmp);
}
}
$games = array (
array(array("player"=>7,"gol"=>1),array("player"=>9,"gol"=>1)),
array(array("player"=>10,"gol"=>1),array("player"=>9,"gol"=>1)),
); //Input array
$player = array();
foreach($games as $game) foreach($game as $gol) //For game and gol
#$player[$gol["player"]]+=$gol["gol"]; //sum gols
arsort($player); //sort by value
print_r($player);
Output
Array
(
[9] => 2
[10] => 1
[7] => 1
)
Naive way (I took the sample from FAEWZX answer ):
$games = array (
array(array("player"=>7,"gol"=>1),array("player"=>9,"gol"=>1)),
array(array("player"=>10,"gol"=>1),array("player"=>9,"gol"=>1)),
);
$player = array();
foreach($games as $game)
{
foreach($game as $gol)
{
if(in_array($gol['player'], array_column($player, 'player')))
{
foreach($player as $key => $value)
{
if($value['player'] == $gol['player'])
{
$player[$key]['gol'] += $gol['gol'];
break;
}
}
}
else
{
$player[] = $gol;
}
}
}
print_r($player);
Output :
Array
(
[0] => Array
(
[player] => 7
[gol] => 1
)
[1] => Array
(
[player] => 9
[gol] => 2
)
[2] => Array
(
[player] => 10
[gol] => 1
)
)

In for loop how to check current value with each and every previous value using php
my array:
In array list [prolabelpos] =>0 having three times, how to execute a [prolabelpos] =>0 only one time in for loop . how to check current array with all previous value and [prolabelpos] =>0 execute once in the for loop
Array (
[0] => Array ( [productlabel_id] => 6 [prolabelpos] => 0 )
[1] => Array ( [productlabel_id] => 5 [prolabelpos] => 6 )
[2] => Array ( [productlabel_id] => 4 [prolabelpos] => 0 )
[3] => Array ( [productlabel_id] => 3 [prolabelpos] => 5 )
[4] => Array ( [productlabel_id] => 2 [prolabelpos] => 0 )
)
my code:
<?php
$prev = null;
foreach ($result as $key => $value) {
$label_position = $value['prolabelpos'];
if ($prev != $label_position) {
echo "my code";
}
$prev = $label_position;
}
You can approach this in foreach OR array_map
$arr =
Array (
'0' => Array ( 'productlabel_id' => 6, 'prolabelpos' => 0 ),
'1' => Array ( 'productlabel_id' => 5, 'prolabelpos' => 6 ),
'2' => Array ( 'productlabel_id' => 4, 'prolabelpos' => 0 ),
'3' => Array ( 'productlabel_id' => 3, 'prolabelpos' => 5 ),
'4' => Array ( 'productlabel_id' => 2 ,'prolabelpos' => 0 )
);
$traversed = array();
foreach($arr as $value){
if(in_array($value['prolabelpos'], $traversed)){
//This has been traversed before
}else{
/* Apply your Logic */
$traversed[] = $value['prolabelpos'];
}
}
Using array_map
$arr = Array (
'0' => Array ( 'productlabel_id' => 6, 'prolabelpos' => 0 ),
'1' => Array ( 'productlabel_id' => 5, 'prolabelpos' => 6 ),
'2' => Array ( 'productlabel_id' => 4, 'prolabelpos' => 0 ),
'3' => Array ( 'productlabel_id' => 3, 'prolabelpos' => 5 ),
'4' => Array ( 'productlabel_id' => 2 ,'prolabelpos' => 0 )
);
$traversed = array();
array_map(function($v) use (&$traversed){
if(in_array($v['prolabelpos'], $traversed)){
//This has been traversed before
}else{
/* Apply your Logic */
$traversed[] = $v['prolabelpos'];
}
}, $arr);
Php multidimensional array same key’s same value’s related total in
new array. I have an array of following mentioned. i need new array
as total qty of same item_id. anyone can help would be appreciate.
My Original Array is as following
Array
(
[a] => Array
(
[item] => Array
(
[item_id] => 1
)
[qty] => 0
),
[b] => Array
(
[item] => Array
(
[item_id] => 2
)
[qty] => 35
),
[c] => Array
(
[item] => Array
(
[item_id] => 2
)
[qty] => 15
),
[e] => Array
(
[item] => Array
(
[item_id] => 3
)
[qty] => 20
),
);
I want array Output like following :
Array(
[0] => Array (
[item_id] => 1,
[item_total_qty] => 0,
)
[1] => Array (
[item_id] => 2,
[item_total_qty] => 50,
)
[2] => Array (
[item_id] => 3,
[item_total_qty] => 20,
)
);
Hope it help
$arrays = array(
'a' => array(
'item' => array(
'item_id' => 1
),
'qty' => 0
),
'b' => array(
'item' => array(
'item_id' => 2
),
'qty' => 35
),
'c' => array(
'item' => array(
'item_id' => 2
),
'qty' => 15
),
'd' => array(
'item' => array(
'item_id' => 3
),
'qty' => 20
)
);
$result = array();
foreach ($arrays as $key => $array) {
if (is_array($result) && !empty($result)) {
foreach ($result as $key => $r) {
if ($r['item_id'] == $array['item']['item_id']) {
$result[$key]['item_total_qty'] += $array['qty'];
continue 2;
}
}
$result[] = array(
'item_id' => $array['item']['item_id'],
'item_total_qty' => $array['qty']);
} else {
$result[] = array(
'item_id' => $array['item']['item_id'],
'item_total_qty' => $array['qty']);
}
}
Simple foreach on your original table:
$sorted = array();
foreach ($original as $item) {
$id = $item['item']['item_id'];
$sorted[$id]['item_total_qty'] = $sorted[$id] ? $sorted[$id] + $item['qty'] : item['qty'];
$sorted[$id]['item_id'] = $id;
}
$sorted = array_values($sorted);
I'm trying to read a session variable, create arrays and concatenate them :
Session variable sample:
Array
(
[0] => Array
(
[idArticle] => 224
[ntypeArticle] => 1
)
[1] => Array
(
[idArticle] => 556
[ntypeArticle] => 2
)
[2] => Array
(
[idArticle] => 312
[ntypeArticle] => 1
)
)
I need to read this arrays one by one and create arrays by "ntypeArticle".
If ntypeArticle=1, create array1
If ntypeArticle=2, create array2
My code :
$type1 = array();
$type2= array();
$typeAll = array();
foreach($_SESSION['cart'] as $item)
{
if ($item['ntypeArticle'] == 1) {
$type1= array ( "Type" => '1', );
} else {
$type2= array ( "Type" => '2', );
}
array_push($typeAll , $type1 , $type2);
}
But this creates empty arrays.
Wanted output :
Array
(
[0] => Array
(
[type] => 1
)
[1] => Array
(
[type] => 2
)
[2] => Array
(
[type] => 1
)
)
All you need is this simple thing:
$out = [];
foreach($_SESSION['cart'] as $k => $item)
{
$out[$k] = ['Type' => $item['ntypeArticle']];
}
Now if you output $out variable you get what you need.
Try This
$newOp1 = array()
$newOp2 = array()
foreach($_SESSION['cart'] as $item){
if($item["ntypeArticle"] == 1){
$newOp1[]['type'] = $item["ntypeArticle"]
}else{
$newOp2[]['type'] = $item["ntypeArticle"]
}
}
print_r($newOp1);
print_r($newOp2);
Basing on information you provided, all you want to do is to extract nTypeArticle as type element. That's all.
//array from your example
$inputArray = array(
array(
'idArticle' => 224,
'nTypeArticle' => 1
),
array(
'idArticle' => 556,
'nTypeArticle' => 2
),
array(
'idArticle' => 312,
'nTypeArticle' => 1
),
);
$outputArray = array_map(function($inputElement) {
return array('type' => $inputElement['nTypeArticle']);
}, $inputArray);
var_dump($outputArray);
//Output (the same as yours):
//array (size=3)
// 0 =>
// array (size=1)
// 'type' => int 1
// 1 =>
// array (size=1)
// 'type' => int 2
// 2 =>
// array (size=1)
// 'type' => int 1
$output = new array();
$input = array(
array(
"idArticle" => 224,
"nTypeArticle" => 1
),
array(
"idArticle" => 556,
"nTypeArticle" => 2
),
array(
"idArticle" => 312,
"nTypeArticle" => 1
)
);
foreach($input as $article) {
array_push($output, new array("type"=>$article["nTypeArticle"]));
}
print_r($output);
This gives you the thing you asked for.
(Code has been not tested)
I have below array,
Array ( [0] => Array ( [report_id] => 1 [amount] => 100.00 [category_name] => Trial1 ) [1] => Array ( [report_id] => 1 [amount] => 150.00 [category_name] => Trial2 ) [2] => Array ( [report_id] => 1 [amount] => 200.00 [category_name] => Trial2 )
What i want to send to have JSON with below format
It will get some of Equal category name and then send it as json.
[{'category_name': 'Trial1', 'Sum':100]}, {'category_name':'Trial2', 'Sum':350]
How can i achieve this?
Was thinking to get foreach loop and then make compare of category_name and use .=+ to get sum? but i lost there,
Thanks,
Try below solution:
<?php
$array = array (
'0' => Array ( 'report_id' => 1, 'amount' => '100.00', 'category_name' => 'Trial1' ) ,
'1' => Array ( 'report_id' => 1, 'amount' => '150.00' ,'category_name' => 'Trial2' ),
'2' => Array ( 'report_id' => 1, 'amount' => '200.00' ,'category_name' => 'Trial2' ) ,
);
$new_array = array();
foreach($array as $a){
if(!isset($new_array[$a['category_name']]['amount'])){
$new_array[$a['category_name']]['amount'] = 0;
}
$new_array[$a['category_name']] = array(
'category_name' => $a['category_name'],
'amount' => $new_array[$a['category_name']]['amount'] + $a['amount'],
);
}
//print_r(array_values($new_array));
echo json_encode(array_values($new_array));
Output
[{"category_name":"Trial1","amount":100},{"category_name":"Trial2","amount":350}]
Possible solution:
$categoriesArray = array();
foreach ($yourArray as $arrayItem) {
if (!isset($categoriesArray[$arrayItem['category_name']])) {
$categoriesArray[$arrayItem['category_name']] = array(
'category_name' => $arrayItem['category_name'],
'sum' => 0
);
}
$categoriesArray[$arrayItem['category_name']]['sum'] += $arrayItem['amount'];
}
$categoriesArray = json_encode(array_values($categoriesArray));
Assuming $input is your array and $output is the JSON string:
$categorysum = [];
array_walk($input, function($el) use (&$categorysum) {
$categorysum += [$el['category_name'] => ['category_name' => $el['category_name'], 'Sum' => 0]];
$categorysum[$el['category_name']]['Sum'] += $el['amount'];
});
$output = json_encode(array_values($categorysum));
$series = array();
while($row = mysql_fetch_assoc($result)) {
$series[$row["data_id"]][] = $row;
}
The output from a print_r on $series yields for two example series:
Array (
[1] => Array ( [0] => Array ( [id] => 1 [data_id] => 1 [time_id] => 1
[data] => 1 ) [1] => Array ( [id] => 2 [data_id] => 1 [time_id] => 2
[data] => 3 ) )
[2] => Array ( [0] => Array ( [id] => 6 [data_id] => 2 [time_id] => 1
[data] => 7 ) [1] => Array ( [id] => 7 [data_id] => 2 [time_id] => 2
[data] => 4 ) )
My question: how do I unset the multidimensional array so it contains only [data] and none of the other keys? I still want $series to contain [1] and [2] but I do not want the respective sub-arrays to contain any other keys other than [data].
In fact, since I am reducing the subarrays to contain a single key, I would really like to get rid of the subarrays altogether so that I have two arrays:
$series[1] = array(1,3) and
$series[2] = array(7,4)
Try this :
$series = array();
while($row = mysql_fetch_assoc($result)) {
$series[$row["data_id"]][] = $row['data'];
}
I think you can loop in your array and build a new one keeping only data details
$array = array ('1' => array ( '0' => array ( 'id' => 1, 'data_id' => 1, 'time_id' => 1, 'data' => 1 ), '1' => array ( 'id' => 2, 'data_id' => 1, 'time_id' => 2, 'data' => 3 ), ),
'2' => array ( '0' => array ( 'id' => 6, 'data_id' => 2, 'time_id' => 1, 'data' => 7 ), '1' => array ( 'id' => 7, 'data_id' => 2, 'time_id' => 2, 'data' => 4 ) ));
$i= 0;
$n= 0;
$series = array();
foreach($array as $dato)
{
$series[$i] = array();
foreach($dato as $data)
{
foreach($data as $key => $value)
{
if($key == 'data')
{
$series[$i][$n] = $value;
$n++;
}
}
}
$n = 0;
$i++;
}
var_dump($series);
This will output
array (size=2)
0 =>
array (size=2)
0 => int 1
1 => int 3
1 =>
array (size=2)
0 => int 7
1 => int 4
