How to fill in a single tournament selection randomly in PHP without repeating?
If I have this:
$players = array("A","B","C","D","E","F","G","H","I","J","L","M","N","O","P","Q");
How can I fill one tournament exception like:
Matche 1: AxL
Matche 2: CxJ
Matche 3: HxQ
.
.
.
Matche 8: ExP
16 Players = 8 Matches
I try this and other codes too:
<?php
$players = array("A","B","C","D","E","F","G","H","I","J","L","M","N","O","P","Q");
shuffle ($players);
foreach($players as $key=>$value)
{
echo $value.','.$value.'<br>';
}
?>

This should work for you:
Just shuffle()
your array and then array_chunk()
into groups of 2, like
<?php
$players = ["A","B","C","D","E","F","G","H","I","J","L","M","N","O","P","Q"];
shuffle($players);
$players = array_chunk($players, 2);
foreach($players as $match => $player)
echo "Match " . ($match+1) . ": " . $player[0] . "x" . $player[1] . "<br>";
?>
