<?php
//This might help full
$arr = ['Governance->Policies->Prescriptions->CAS Alerts',
        'Users->User Departments->Department Hierarchy',
        'Settings->Registrar->Finance',
        'Logs->Second Opinion Log'];
        
$result="";
$newline="<br>";
foreach($arr as $data){
    $wordlist=explode('->',$data);
    $firstword=$wordlist[0];
    $temp='';
    foreach($wordlist  as $key=>$value){
      if($key > 0){
        $temp.=$firstword."->".$value.$newline;
      }
    }
    $temp.=$newline;
    $result.=$temp;
