July 1, 2022

is i want Finds data that is in an array.
where it takes data from $data to find data in $data_set
By taking out the same information, for example, get data 3, 4, 1, 5.
Let’s find the information contained in $data_set.
where the desired result is G, B

 $data = [3, 4, 1, 5];
 $data_set = [
   'R' => [3, 2, 1],
   'G' => [3, 4],
   'B' => [1, 5],
 ];

output = G,B

>Solution :

for the question
how to obtain this output = G,B

it’s only a simple search

<?php
$data = [3, 4, 1, 5];
 $data_set = [
   'R' => [3, 2, 1],
   'G' => [3, 4],
   'B' => [1, 5],
 ];

$res='';
foreach( $data_set as $name => $search){
    $s=count($data_set[$name]);
    $x=0;
    foreach($search as $vl){
        if(in_array($vl,$data))  $x++;
    }
    if($s==$x) $res.= ' '.$name.',';
}
echo substr($res,0,-1);
?>
