I am having three arrays

1. topicsSelected


2. relavantGroups


3. topicAssingned

$topicsSelected = [ "T-100","T-600"];

$relavantGroups = [
 [ "id" => "G-001","name" => "3 A","active" => false ], 
 ["id" => "G-002","name" => "3 B","active" => false] 
 ];

$topicAssingned = [
 "G-001" => [
 "groupID" => "G-001",
 "groupName" => "3 A",
 "topics" => [
 "T-100" => [
 "topicID" => "T-100"
 ],
 "T-200" => [
 "topicID" => "T-200"
 ]
 ]
 ],
 "G-002" => [
 "groupID" => "G-002",
 "groupName" => "3 B",
 "topics" => [
 "T-400" => [
 "topicID" => "T-400"
 ],
 "T-500" => [
 "topicID" => "T-500"
 ]
 ]
 ],
];

$topicsSelected array values at least one value should present $topicAssingned means based on groupID, i have to push one value to $relavantGroups like disable : D suppose value not present means disable : A

Expected output:

[
 "id" => "G-001",
 "name" => "3 A",
 "active" => false,
 "disable" => "D"
],
[
 "id" => "G-002",
 "name" => "3 B",
 "active" => false,
 "disable" => "A"
]

<?php 

$topicsSelected = [ "T-100","T-600"];

$relavantGroups = [
 [ "id" => "G-001","name" => "3 A","active" => false ],
 ["id" => "G-002","name" => "3 B","active" => false]
];

$topicAssigned = [
 "G-001" => [
 "groupID" => "G-001",
 "groupName" => "3 A",
 "topics" => [
 "T-100" => [
 "topicID" => "T-100"
 ],
 "T-200" => [
 "topicID" => "T-200"
 ]
 ]
 ],
 "G-002" => [
 "groupID" => "G-002",
 "groupName" => "3 B",
 "topics" => [
 "T-400" => [
 "topicID" => "T-400"
 ],
 "T-500" => [
 "topicID" => "T-500"
 ]
 ]
 ],
];

$topic_selected_map = [];

foreach($topicsSelected as $each_topic)
 $topic_selected_map[$each_topic] = true;


$relevant_group_map = [];

foreach($relavantGroups as $each_group)
 $relevant_group_map[$each_group['id']] = $each_group;


$result = [];

foreach($topicAssigned as $each_assigned_topic)
 if(!isset($relevant_group_map[$each_assigned_topic['groupID']])) continue;

 $topics_not_found = true;
 foreach($each_assigned_topic['topics'] as $each_topic => $topic_details)
 if(isset($topic_selected_map[$each_topic]))
 $topics_not_found = false;
 break;
 
 

 $result[] = [
 'id' => $each_assigned_topic['groupID'],
 'name' => $each_assigned_topic['groupName'],
 'active' => $relevant_group_map[$each_assigned_topic['groupID']]['active'],
 'disable' => ($topics_not_found === true ? 'A' : 'D')
 ];



print_r($result);

Output:

Array
(
 [0] => Array
 (
 [id] => G-001
 [name] => 3 A
 [active] => false
 [disable] => D
 )

 [1] => Array
 (
 [id] => G-002
 [name] => 3 B
 [active] => false
 [disable] => A
 )

)

• First, make a map(associative array) of values of $topicsSelected. Same goes for $relavantGroups. This is to make the check more efficient. See more on Hash Table.




• Now, iterate over $topicAssigned and then iterate over each group's topics inside it. Now, check if a topic exists inside $topicsSelected using a simple isset function. If yes, we disable them, else we don't.

It's not very clear what you are asking and the code is a bit weird but I'll give it a try.
First fix your array declaration - you should use => and not :;

You have to Iterate over the $relavantGroups and for each element iterate the $topicAssingned array. Then perform a simple comparison to see if the group Id is present and you are done!

Here is my solution (quick and dirty): You can see it here

foreach ($relavantGroups as &$g) 
 $found = false;
 foreach ($topicAssingned as $key => $assigned) 
 if ($key === $g["id"] && is_array($assigned["topics"])) 
 foreach ($assigned["topics"] as $topic) 
 if (in_array($topic["topicID"], $topicsSelected)) 
 $found = true;
 break;
 
 
 
 
 $g["disable"] = $found ? "D" : "A";

var_dump($relavantGroups);

Updated the solution - note that I'm using in_array() to determine if the topicID is present. That mean that any value that is in the $topicsSelected array will affect the result.

Hope I helped.

This will output (based one your example):

array(2) 
 [0]=> array(4) 
 ["id"]=> string(5) "G-001"
 ["name"]=> string(3) "3 A"
 ["active"]=> bool(false)
 ["disable"]=> string(1) "D"
 
 [1]=> array(4) 
 ["id"]=> string(5) "G-002"
 ["name"]=> string(3) "3 B"
 ["active"]=> bool(false)
 ["disable"]=> string(1) "A"
