php for loop array length

Question

I have this array:

array('Volvo', 'BMW', 'Toyota', 'Kijang');

And I want results like this

"Volvo","BMW","Toyota","Kijang"
"BMW","Volvo","Toyota","Kijang"
"Toyota","Volvo","BMW","Kijang"
"Kijang","Toyota","Volvo","BMW"

and here's my code :

$products = array('Volvo', 'BMW', 'Toyota', 'Kijang');

$rows = count($products);  

for ($i = 0; $i < $rows; $i++) {

    echo $products[$i] . '<br>';
}

but, unfortunately I missed 3 results :

"BMW","Volvo","Toyota","Kijang"
"Toyota","Volvo","BMW","Kijang"
"Kijang","Toyota","Volvo","BMW"

how to get that missed combination and perfectly works for different array length?

What are you trying to achieve? I'm not seeing how you determined the "results you want", bearing in mind there are 24 permutations of 4 items. — Niet the Dark Absol

You can achieve this in this way as well.

<?php

   $products = array('Volvo', 'BMW', 'Toyota', 'Kijang');
     for($i=0;$i<count($products);$i++){
        echo implode(", ",$products);  
        echo "<br>";
        array_push($products, array_shift($products));
     }

?>

This will give you the following result:

Volvo, BMW, Toyota, Kijang
BMW, Toyota, Kijang, Volvo
Toyota, Kijang, Volvo, BMW
Kijang, Volvo, BMW, Toyota

You can run the code in here.Hope this will help you.

You can achive it in this way

<?php

$products = array('Volvo', 'BMW', 'Toyota', 'Kijang');

foreach($products as $product){
    echo "'".$product."', ";
    foreach($products as $otherProduct){
        if($otherProduct == $product){
            // Skip the element
            continue;
        }
        echo "'".$otherProduct."', ";
    }
    echo "<br>";
}

You need to loop twice to get the result.
