How to check the condition in given three array - php

Question

I am having three arrays
topicsSelected
relavantGroups
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(T-100 or T-600) at least one value should present in $topicAssingned array, based on groupID(G-001). $topicAssingned under topics , topicID : T-100 is present , so Disable : D
$topicsSelected array values(T-100 or T-600) at least one value should present in $topicAssingned array, based on groupID(G-002). $topicAssingned under topics , topicID : T-100 & T-600 is not present , so Disable : A
Expected output:
[
"id": "G-001",
"name": "3 A",
"active": false,
"Disable" : "D"
],
[
"id": "G-002",
"name": "3 B",
"active": false,
"Disable" : "A"
]
My Code
foreach ($relavantGroups as &$g) {
$found = false;
foreach ($topicAssingned as $key => $assigned) {
if ($key === $g["id"]) {
$found = true;
break;
}
}
$g["disable"] = $found ? "D" : "A";
}
echo "<pre>";
print_r($relavantGroups);
My Output
Array
(
[0] => Array
(
[id] => G-001
[name] => 3 A
[active] =>
[disable] => D
)
[1] => Array
(
[id] => G-002
[name] => 3 B
[active] =>
[disable] => D
)
)

Answer 1

You can try this snippet,
foreach ($relavantGroups as &$g) {
$found = false;
foreach ($topicAssingned as $key => $assigned) {
if ($key === $g["id"]) {
$temp = array_keys($assigned['topics']); // fetching all topic ids
$intr = array_intersect($topicsSelected, $temp); // checking if there are any matching values between topicSelected and traversed values
$found = (!empty($intr) ? true : false); // if found return and break
break;
}
}
$g["disable"] = $found ? "D" : "A";
}
print_r($relavantGroups);
array_intersect — Computes the intersection of arrays
array_keys — Return all the keys or a subset of the keys of an array
Output
Array
(
[0] => Array
(
[id] => G-001
[name] => 3 A
[active] =>
[disable] => D
)
[1] => Array
(
[id] => G-002
[name] => 3 B
[active] =>
[disable] => A
)
)
