$temp = '';
for($i = 0; $i < count($arr); $i++){
    $arrVal = [];
    
    $arrVal = explode('->',$arr[$i]);
    if(count($arrVal) > 1){
        for($j=0; $j < count($arrVal); $j++){
            if($j == 0){
                $temp .= $arrVal[$j];
            }else{
                $temp .='->'.$arrVal[$j]."n";
                if($j == count($arrVal) - 1){
                    $temp .= "n";
                }else{
                    $temp .= substr($temp, 0, strpos($temp, "->"));
                }

    Here the solution:

    <?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;
}
echo $result;
?>

    Output :

    Governance->Policies
Governance->Prescriptions
Governance->CAS Alerts

Users->User Departments
Users->Department Hierarchy

Settings->Registrar
Settings->Finance

Logs->Second Opinion Log

  if (count($path_elements) > 1) {
    $path_head = $path_elements[0];
    $path_tail = array_slice($path_elements, 1);
    foreach ($path_tail as $path_item) {
      echo $path_head, '->', $path_item, "<br>";
    }
    echo "<br>";  
  }
}

    Or, using JOIN()

    $arr = ['Governance->Policies->Prescriptions->CAS Alerts',
        'Users->User Departments->Department Hierarchy',
        'Settings->Registrar->Finance',
        'Logs->Second Opinion Log'];

foreach ($arr as $path) {
  $path_elements = explode('->', $path);
  if (count($path_elements) > 1) {
    $path_head = $path_elements[0];
    $path_tail = array_slice($path_elements, 1);
    echo
      $path_head,
      '->',
      join('<br>'. $path_head.'->',$path_tail),
      '<br><br>';
  }
}

    As you iterate your array of arrow-delimited strings, explode each element on its arrows, separate the the first value from the rest, then iterate the remaining elements from the explosion and prepend the cached, first value and push into the result array.

    Code: (Demo)

    $result = [];
foreach ($arr as $string) {
    $parts = explode('->', $string);
    $parent = array_shift($parts);
    foreach ($parts as $child) {
        $result[] = "{$parent}->$child";
    }
}
var_export($result);
