PHP - create a tournament results order from array - php

Question

Consider I have a following array of total scores, with each value being a score of a player in a tournament.
$total_scores = array(350,200,150,150,75,75,75,0);
I need to create a table, which lists the players with correct positions, if they have the same score, the listing should reflect this, ie.:
1. Player 1 350
2. Player 2 200
3.-4. Player 3 150
3.-4. Player 4 150
5.-7. Player 5 75
5.-7. Player 6 75
5.-7. Player 7 75
8. Player 8 0
I tried to do something with
foreach ($total_scores as $total_score) {
$no_of_occurrences = array_count_values($total_scores)[$total_score];
}
But cannot figure out how to build the correct positions numbering.

<?php
$scores = array(350,200,150,150,75,75,75,0); //assuming you have sorted data otherwise you need to sort it first
$count = array();
$startIndex = array();
$endIndex = array();
$len = count($scores);
for($i = 0; $i < $len; $i++){
if(!isset($count[$scores[$i]])){
$count[$scores[$i]] = 1;
$startIndex[$scores[$i]] = $endIndex[$scores[$i]] = $i+1;
}else{
$count[$scores[$i]]++;
$endIndex[$scores[$i]] = $i+1;
}
}
$i = 1;
foreach($scores as $s){
echo $startIndex[$s].'.';
if($startIndex[$s] != $endIndex[$s]){
echo '-'.$endIndex[$s].'.';
}
echo ' Player '.$i.' '.$s."\n"; //if newline not works try echoing <br>
$i++;
}

For this Array needs to be sorted in descending order
$total_scores = array(350, 200, 150, 150, 75, 75, 75, 0);
rsort($total_scores);
$no_of_occurrence = array_count_values($total_scores);
array_unshift($total_scores, ""); // For starting count from 1
unset($total_scores[0]); // For starting count from 1
$i = 1;
foreach ($total_scores as $key => $value)
{
$position = array_keys($total_scores,$value);
if($no_of_occurrence[$value] == 1)
{
echo "Position " . $i . " ";
echo "Player " . $i . " " . $value . " ";
}
else
{
echo "Position " . $position[0] . " - " . end($position) . " ";
echo "Player " . $i . " " . $value . " ";
}
$i++;
echo "<br>";
}
Output of above code :
Position 1 Player 1 350
Position 2 Player 2 200
Position 3 - 4 Player 3 150
Position 3 - 4 Player 4 150
Position 5 - 7 Player 5 75
Position 5 - 7 Player 6 75
Position 5 - 7 Player 7 75
Position 8 Player 8 0
