how to make incremental value in hierarchal array in Php? - php

Hi guys I was wondering how can I add a incremental all elements? Because as of now I am not sure where can I include the "inc" in all elements
Ex:
MY_ARRAY = (
[id] => 4
[children] => Array
(
[0] => Array
(
[id] => 18
[children] => Array
(
[0] => Array
(
[id] => 21
)
[1] => Array
(
[id] => 22
)
)
)
[1] => Array
(
[id] => 19
)
[2] => Array
(
[id] => 20
[children] => Array
(
[0] => Array
(
[id] => 26
)
)
)
)
)
Using these code:
$in = MY_ARRAY
function generateArray($in, $parent = 0){
foreach ($in as $key => $value) {
if(is_numeric($key)){
$in = $value;
$out[$key] = $this->generateArray($in, $parent);
}else{
$out[$key]=$value;
if($key=="id"){
$out['p_id'] = $parent;
$parent=$value;
}elseif($key=="children"){
$in = $value;
$out[$key] = $this->generateArray($in, $parent);
}
}
}
return $out;
}
Will give me this output, not including the [inc].
[id] => 4
[P_id] => 0
[inc] => 1
[children] => Array
(
[0] => Array
(
[id] => 18
[P_id] => 4
[inc] => 2
[children] => Array
(
[0] => Array
(
[id] => 21
[P_id] => 18
[inc] => 3
)
[1] => Array
(
[id] => 22
[P_id] => 18
[inc] => 4
)
)
)
[1] => Array
(
[id] => 19
[P_id] => 4
[inc] => 5
)
[2] => Array
(
[id] => 20
[P_id] => 4
[inc] => 6
[children] => Array
(
[0] => Array
(
[id] => 26
[P_id] => 20
[inc] => 7
)
)
)
)
)
Now I'm not sure where and how can I include the [inc] or the incremental value of each element in the array using my code above.
Need really help here guys...

How to get value of all same keys of multidimentional array in php

Basically i want to loop through a multidimensional associative array to get a simple indexed array
Here is my master array
Array
(
[0] => Array
(
[user_id] => 2
[children] => Array
(
[0] => Array
(
[user_id] => 5
[children] => Array
(
)
)
[1] => Array
(
[user_id] => 6
[children] => Array
(
)
)
)
)
[1] => Array
(
[user_id] => 3
[children] => Array
(
[0] => Array
(
[user_id] => 7
[children] => Array
(
)
)
[1] => Array
(
[user_id] => 8
[children] => Array
(
)
)
)
)
[2] => Array
(
[user_id] => 4
[children] => Array
(
[0] => Array
(
[user_id] => 9
[children] => Array
(
[0] => Array
(
[user_id] => 10
[children] => Array
(
[0] => Array
(
[user_id] => 11
[children] => Array
(
)
)
[1] => Array
(
[user_id] => 12
[children] => Array
(
)
)
[2] => Array
(
[user_id] => 13
[children] => Array
(
)
)
)
)
)
)
)
)
)
Here is the result i want to achive
$userArray= array(2,3,4,5,6,7,8,9,10,11,12,13);
basically i just want all the user_id key value inside 1 single indexed array.
Till now i have tried this code
$keys = array_keys($masterArray);
for($i = 0; $i < count($masterArray); $i++) {
echo $keys[$i] . "{<br>";
foreach($masterArray[$keys[$i]] as $key => $value) {
echo $key . " : " . $value . "<br>";
}
echo "}<br>";
}
You can use array_walk_recursive() which will iterate over the leaf nodes in a multidimensional array, check for the key being user_id and if so, add it to a list of ids...
$ids = [];
array_walk_recursive($masterArray, function ( $value, $key) use (&$ids) {
if ( $key == "user_id" ) {
$ids[] = $value;
}
});
print_r($ids);
which with the sample data, gives...
Array
(
[0] => 2
[1] => 5
[2] => 6
[3] => 3
[4] => 7
[5] => 8
[6] => 4
[7] => 9
[8] => 10
[9] => 11
[10] => 12
[11] => 13
)
You just have to travel recursively to collect all user IDs as below:
<?php
function collectUserIDs($data,&$result){
foreach($data as $current_data){
$result[] = $current_data['user_id'];
collectUserIDs($current_data['children'],$result);
}
}
$result = [];
collectUserIDs($data,$result);
print_r($result);

Compare values of two multidimentional array and insert if not exits

I have two array $array1 and $array2 which I get dynamically and look like
$array1 = Array
(
[0] => Array
(
[hour] => 10
[activity] => Array
(
[0] => Array
(
[activity_id] => 1
[cnt] => 2
)
[1] => Array
(
[activity_id] => 2
[cnt] => 1
)
)
)
[1] => Array
(
[hour] => 11
[activity] => Array
(
)
)
[2] => Array
(
[hour] => 12
[percentage] => 0
[activity] => Array
(
[0] => Array
(
[activity_id] => 2
[cnt] => 5
)
[1] => Array
(
[activity_id] => 3
[cnt] => 2
)
)
)
);
$array2 = Array
(
[0] => Array
(
[id] => 1
[name] => Phone Calls
[readable] => 1
[status] => active
)
[1] => Array
(
[id] => 2
[name] => Meeting With Customer
[readable] => 1
[status] => active
)
[2] => Array
(
[id] => 3
[name] => Others Works
[readable] => 1
[status] => active
)
);
which i need to compare.
if $array2['id'] is not in $array1["activity"](i.e"activity_id") add array ['activity_id'=>$array2['id'],'cnt'=>0] to $array1['activity'].
My result must be like
$result = Array
(
[0] => Array
(
[hour] => 10
[activity] => Array
(
[0] => Array
(
[activity_id] => 1
[cnt] => 2
)
[1] => Array
(
[activity_id] => 2
[cnt] => 1
)
[2] => Array
(
[activity_id] => 3
[cnt] => 0
)
)
)
[1] => Array
(
[hour] => 11
[activity] => Array
(
[0] => Array
(
[activity_id] => 1
[cnt] => 0
)
[1] => Array
(
[activity_id] => 2
[cnt] => 0
)
[2] => Array
(
[activity_id] => 3
[cnt] => 0
)
)
)
[2] => Array
(
[hour] => 12
[percentage] => 0
[activity] => Array
(
[0] => Array
(
[activity_id] => 1
[cnt] => 0
)
[1] => Array
(
[activity_id] => 2
[cnt] => 5
)
[2] => Array
(
[activity_id] => 3
[cnt] => 2
)
)
)
);
What i have tried is
$finalArray = array();
foreach($array1 as $arr1) {
foreach($array2 as $arr2) {
if(!in_array($arr2['id'], $arr1['activity'])) {
$array = ['activity_id'=>$arr2['id'], 'cnt'=>0];
}
array_push($arr1['activity'], $array);
unset($array);
}
array_push($finalArray, $result);
}
print_r($finalArray);
in_array() function is not working as I excepted or I am trying to do it in the wrong way. Can someone helps me with this?
Sorry,finally i get what i did wrong.May be someone get helped.
everything is ok just change the line
if(!in_array($arr2['id'], $arr1['activity'])) {
into
if(!in_array( $readActivity['id'], array_column($result['activity'],'activity_id'))){

recursive function to transform multidimentional array

I have an array after an SQL query made with cake PHP which returns me a tree. I do not the number of dimension of my array.
I want transform it to use it with jstree. I'm fighting with a recursive function and I didn't success.
Can you help me.
My original array looks like this:
Array
(
[0] => Array
(
[Confsave] => Array
(
[id] => 815
[Name] => 1
[parent_id] =>
[lft] => 1
[rght] => 30
)
[children] => Array
(
[0] => Array
(
[Confsave] => Array
(
[id] => 816
[Name] => 2
[parent_id] => 815
[lft] => 2
[rght] => 15
)
[children] => Array
(
[0] => Array
(
[Confsave] => Array
(
[id] => 817
[parent_id] => 816
[lft] => 3
[rght] => 8
)
[children] => Array
(
[0] => Array
(
[Confsave] => Array
(
[id] => 818
[Name] => 4
[parent_id] => 817
[lft] => 4
[rght] => 5
)
[children] => Array
(
)
)
[1] => Array
(
[Confsave] => Array
(
[id] => 819
[Name] => 5
[parent_id] => 817
[lft] => 6
[rght] => 7
)
[children] => Array
(
)
)
)
)
)
)
)
)
)
And I want have something like this :
Array
(
[0] => Array
(
[text] => 1
[id] => 815
[children] => Array
(
[0] => Array
(
[text] => 2
[id] => 816
[children] => Array
(
[0] => Array
(
[text] => 3
[id] => 817
[children] => Array
(
[0] => Array
(
[text] => 4
[id] => 818
)
)
)
[1] => Array
(
[text] => 5
[id] => 819
)
)
)
)
)
)
I have try with a recursive function like this but I don't success
private function buildTree(array $elements) {
$branch=array();
foreach ($elements as $element){
$branch[]=$element['Confsave']['Name'];
if(is_array($element['children'])){
$this->buildTree($element);
}
}
return $branch;
}
Edit :
After test and remarks my function is now
private function buildTree(array $elements) {
$branch=array();
foreach ($elements as $element){
$branch[]=$element['Confsave']['Name'];
if(is_array($element['children'])){
$this->buildTree($element['children']);
}
}
return $branch;
}
When I am debuging, I can see that I go to my function for each child (what I want). But I don't know how to make the new array()
this worked for me...
$array = buildTree($array);
print_r($array);
function buildTree(array $parent) {
$branch = array();
foreach ($parent as $index => $element){
$node = array();
$node['id'] = $element['Confsave']['id'];
$node['text'] = isset($element['Confsave']['Name']) ?
$element['Confsave']['Name'] : 'no name';
$node['children'] = buildTree($element['children']);
$branch[] = $node;
}
return $branch;
}

i want to show set to array which is not empty, if search hits empty array then count upto 10 still empty array then close array and continue

in the following array i want to show from array[0] to array[2] is pack1, array[5] to array[10] pack2, array[10] to array[12] is pack3 pack4 starts from array[14]. (if empty array is above 2 then close the pack and start another pack)
array

array difference

I have this array lets call it array 1
Array
(
[0] => Array
(
[Machine] => Array
(
[id] => 7
[name] => XYZ
[priority] => 1
)
[Software] => Array
(
[id] => 472
)
)
[1] => Array
(
[Machine] => Array
(
[id] => 6
[name] => ABC
[priority] => 0
)
[Software] => Array
(
[id] => 470
)
)
[2] => Array
(
[Machine] => Array
(
[id] => 1
[name] => IEU
[priority] => 3
)
[Software] => Array
(
[id] => 471
)
)
)
Then I have another array lets call it array 2
Array
(
[0] => 7
[1] => 5
[2] => 4
[3] => 3
[4] => 6
)
If array 2 doesnt have [Machine][id] then I want it to be removed from array 1. Like in above example 1 will removed
[2] => Array
(
[Machine] => Array
(
[id] => 1
[name] => IEU
[priority] => 3
)
[Software] => Array
(
[id] => 471
)
)
any idea on how to achieve that. Thanks
Perhaps..
foreach ($array1 AS $key => $array) {
if (!in_array($array['Machine']['id'], $array2))
unset($array1[$key]);
}
try something like :
$new_array = array();
foreach ($array1 as $platform)
{
if (in_array($platform["Machine"]["id"], $array2))
{
$new_array[] = $platform;
}
}
return $new_array;
