php variable based on a random variable

I'm new to php and I wrote a code that takes a random winner out of an array and displays it, then I wanted to try to display all the names without the winner's, but how can I unset the winner by using the random number generated? I managed to unset a random name but not the same as the winner...

    <?php

// array

$winner = array();
    array_push($winner,"sonia");
    array_push($winner,"ice");
    array_push($winner,"sasha");
    array_push($winner,"isa");
    array_push($winner,"omar");
    array_push($winner,"anwar");

// random winner

    $giocatori = count($winner);   
        $random = rand(0,$giocatori -1);   
            unset($winner[$random]);

// Sort the list

sort($winner);
    echo "I giocatori sono: ";
        print join(", ",$winner);

// Print the winner's name in ALL CAPS

$truewinner = strtoupper($winner[$random]);
    echo "<br><br>";
    echo "il vincitore è: ";

// Print winner + sentence   

$losers = "losers";
$losers = strtoupper($losers);    
    echo (strtoupper($winner[$random]));
    echo "<br><br>";
    echo "all the players are: $losers beside $truewinner"; 

?>

How to write the array:

$participants = array("sonia", "ice", "sasha","isa","omar","anwar");
or
$participants = array();
$participants[] = "sonia";
$participants[] = "ice";
and soo on

//make all participants name first letter uppercase
$participants = array_map(function($string) {return ucfirst($string);},$participants);

To get an random value from the array you have:

//get a random key
$random = array_rand($participants);
//get the value for the key
$winner = $participants[$random];
//unset the key and value
unset($participants[$random]);

OR

//this will shuffle values in the array on random positions
shuffle($participants);
//this return the last value from the array and deletes it from the array
$winner = array_pop($participants);


echo "The winner is $winner !\n";
echo "The losers are ".implode(', ',$participants)."\n";

<?php

// array

$winner = array();
array_push($winner,"sonia");
array_push($winner,"ice");
array_push($winner,"sasha");
array_push($winner,"isa");
array_push($winner,"omar");
array_push($winner,"anwar");

// random winner

$giocatori = count($winner);   
$random = rand(0,$giocatori -1);
echo "winner is".$winner[$random];
unset($winner[$random]);

// Sort the list

sort($winner);
echo print_r($winner) ;


echo "losers are ";
foreach($winner as $res) {
 echo $res. ' ';
}

?>

Output

winner is anwar
