PHP Variable basierend auf einer Zufallsvariablen

Question

Ich bin neu in php und ich schrieb einen Code, der einen zufälligen Gewinner aus einem array und zeigt es an, dann wollte ich versuchen, alle Namen ohne die Gewinner anzuzeigen, aber wie kann ich unset den Gewinner mit der Zufallszahl generieren? Ich schaffte es unset einen zufälligen Namen, aber nicht das gleiche wie die Gewinner ...

<?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"; 

?> 

Answer 1

$players = array('sonia', 'ice', 'sasha', 'isa', 'omar'); 
$random = rand(0, count($players) - 1); 
$winner = $players[$random]; 
$losers = array_diff($players, array($winner)); 

echo 'All players are: ' . implode(', ', $players); 
echo 'Winner is: ' . $winner; 
echo 'Losers are: ' . implode(', ', $losers);

<?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. ' '; 
} 

?>

Answer 3

Wie das Array schreiben:

$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); 

Um einen zufälligen Wert aus dem Array zu erhalten, haben Sie:

//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]); 

ODER

//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";
