Count occurrences of a value inside a multidimensional array - php

Question

so i retrieve a json, convert it into an array and i got this output:
Array
(
[Sid] => 23888555
[pages] => Array
(
[0] => Array
(
[id] => 13111071
[name] => Page 1
[slots] => Array
(
[0] => Array
(
[SlotId] => 6
[info] => Array
(
[id] => 5247
[color] => red
)
)
[1] => Array
(
[SlotId] => 4
[info] => Array
(
[id] => 5267
[color] => blue
)
)
[2] => Array
(
[SlotId] => 7
[info] => Array
(
[id] => 5267
[color] => green
)
)
)
)
[1] => Array
(
[id] => 13111072
[name] => Page 2
[slots] => Array
(
[0] => Array
(
[SlotId] => 6
[info] => Array
(
[id] => 5247
[color] => red
)
)
[1] => Array
(
[SlotId] => 4
[info] => Array
(
[id] => 5267
[color] => blue
)
)
)
)
)
)
I have no problem reading it whatsoever, what i wanna do is count for every page how many similar "last" id i got.
Exemple :
[pages][0][slots][0][info][id]
[pages][0][slots][1][info][id]
[pages][0][slots][3][info][id]
For the page 1, I wanna compare these 3 ids between them and count the occurrences.
[pages][1][slots][0][info][id]
[pages][1][slots][1][info][id]
For the page 2, I wanna compare these 2 ids between them and count the occurrences.
The output i want looks like this :
page 1 -> 1x5247
-> 2x5267
page 2 -> 1x5247
-> 1x5267
EDIT :
I tried using
foreach ($data['pages'] as $item) {
foreach ($item['slots'] as $slotnumber => $value) {
print_r(array_count_values($item['slots'][$slotnumber]['info']));
}
}
which returns me this :
Array ( [5247] => 1 [red] => 1 )
Array ( [5267] => 1 [blue] => 1 )
Array ( [5267] => 1 [green] => 1 )
So i think i might be able to use this but i don't know how.

Answer 1

I manually declared the array and then created the countstuff() function. This should work for you. I tested it and it work on my end. After going through all this trouble, I really do appreciated it if you choose my answer and up vote it.
<?php
$data = Array("Sid" => "23888555", "pages" => Array("0" => Array("id" => "13111071", "name" => "Page 1", "slots" => Array("0" => Array("SlotId" => "6", "info" => Array("id" => "5247", "color" => "red")), "1" => Array("SlotId" => "4", "info" => Array("id" => "5267", "color" => "blue")), "2" => Array("SlotId" => "7","info" => Array("id" => "5267", "color" => "green")))),
"1" => Array
(
"id" => "13111072",
"name" => "Page 2",
"slots" => Array
(
"0" => Array
(
"SlotId" => "6",
"info" => Array
(
"id" => "5247",
"color" => "red"
)
),
"1" => Array
(
"SlotId" => "4",
"info" => Array
(
"id" => "5267",
"color" => "blue"
)
)
)
)
)
);
//End of array declaration
//Now the really convoluted coding starts
//Create a function
function countstuff($yourarray){
foreach($yourarray as $mainarraykey => $mainarray){
if($mainarraykey == "pages"){
foreach($mainarray as $pageskey => $pagesarray){
//echo "Page \"$pageskey\"<br/>";
foreach($pagesarray as $pagessubarraykey => $pagessubarray_array){
if($pagessubarraykey == "slots"){
foreach($pagessubarray_array as $slotskey => $slots){
foreach($slots as $slotssubkey => $slotssub){
if($slotssubkey == "info"){
foreach($slotssub as $key => $value){
if($key == "id"){
//echo $value."<br/>";
$pages[$pageskey][] = $value;
}
}
}
}
}
}
}
}
}
}
return $pages;
}
//Execute the countstuff() function
$output = countstuff($data);
function showresults($input){
foreach($input as $pagekey => $page){
echo "Page $pagekey:<br/>";
$results = array_count_values($page);
foreach($results as $resultkey => $result){
echo $result."x".$resultkey."<br/>";
}
echo "<br/>";
}
}
showresults($output);
?>

I tried some things let me know what you guys think of this.
I get every id then enter them into an array then use array_count_values
$array_ids = array();
foreach ($data['pages'] as $item) {
$numberOfElements = count($item['slots']);
$z= 0;
foreach ($item['slots'] as $slotnumber => $value) {
$array_ids[$z] = $item['slots'][$slotnumber]['info']['id'];
// search for occurrences when the array is full
if (count($array_ids) == $numberOfElements) {
var_dump(array_count_values($array_ids));
// reset the array to 0 every time we loop through the whole infos
$array_ids = array();
}
$z++;
}
}
This seems to work for every page.
array (size=2)
5267 => int 2
5247 => int 1
array (size=2)
5267 => int 1
5247 => int 1
