This question doesn't really offer enough clarity. There are some techniques (in the answers below) that will work on this sample input but not work if there are multiple `id`s. Please provide a better, more complex [mcve]. — mickmackusa, Aug 21 '22 at 04:02

$output = array();

$arrayAB = array_merge($arrayA, $arrayB);
foreach ( $arrayAB as $value ) {
    $keys = array("id", "icd", "rank", "description"); 
    foreach ($keys as $key) {
        $currKey = $value[$key];
        if ( !isset($output[$currKey]) ) {
            $output[$currKey] = array();
        }
        $output[$currKey] = array_merge($output[$currKey], $value);
    }
}

var_dump($output);

$new_array = array();
foreach($your_array as $row){
         $new_array['id']        = $row->id;
         $new_array['icd'][] = $row->icd;
         $new_array['description'][] = $row->description; 
}
print_r($new_array);
