Get first value of array and store in new array php - php

Question

I am trying to make card game.
I have 6 variable that are stored in array. Than I use fisherYates method to randomize array, and display four of them.
Problem is, when I randomize it this way only, it will give only random output of those six, with all different types.
So I want that some repeats like, if you draw four cards, you get output of
ex: club, club, diamond,heart, or heart, star,star,heart.. if you get a point..
I thought to do it like this way: put the array in loop of 4 times, and every time it loops, it stores first, or last value in new array, so that way, I can have greater chances of combination of same cards in output array.
But I'm stuck, and I don't know how to do it :/
this is what I've tried so far
$diamond = 'cube.jpg';
$heart = 'heart.jpg';
$spade = 'spade.jpg';
$club = 'tref.jpg';
$star='star.jpg';
$qmark='qmark.jpg';
$time=microtime(35);
$arr=[$diamond,$heart,$spade,$club,$star,$qmark];
function fisherYatesShuffle(&$items, $time)
{
for ($i = count($items) - 1; $i > 0; $i--)
{
$j = #mt_rand(0, $i);
$tmp = $items[$i];
$items[$i] = $items[$j];
$items[$j] = $tmp;
}
return $items;
}
$i=0;
do {
$niz[$i]=fisherYatesShuffle($arr,$time);
reset($niz);
$i++;
} while ($i <= 3);

Got a solution. Was just to simply do foreach of first element of multidimensional array :)
Code goes like this:
$diamond = 'cube.jpg';
$heart = 'heart.jpg';
$spade = 'spade.jpg';
$club = 'tref.jpg';
$star='star.jpg';
$qmark='qmark.jpg';
$time=microtime(35);
$arr=[$diamond,$heart,$spade,$club,$star,$qmark];
$niz=array();
$i=0;
do {
$niz[$i]=fisherYatesShuffle($arr,$time);
//reset($niz);
$i++;
} while ($i <= 3);
foreach ($niz as $key ) {
$randomArr[]=$key[0]; ;
}
function fisherYatesShuffle(&$items, $time)
{
for ($i = count($items) - 1; $i > 0; $i--)
{
$j = #mt_rand(0, $i);
$tmp = $items[$i];
$items[$i] = $items[$j];
$items[$j] = $tmp;
}
return $items;
}
print_r($randomArr);
