Permutations help in php

Hi
Actually I was trying a small script that will take two words from two different arrays, then I would like to combine both the arrays.
My first array elements would be some thing like this

Code:

---

r, b, g

---

My second array elements would e some thing like this 3

Code:

---

c, e, m

---

The result I expect is

Code:

---

r c
r e
r m
b c
b e
b m
g c
g e
g m

---

Hello
You would like to try this code. If I am not wrong this will work as you are expecting. Try it.

Code:

---

<?php
 
    $arr1 = array('r', 'b', 'g');
    $arr2 = array('c', 'e', 'm');
    $arr_perm = get_permutations($arr1, $arr2);
    print_r($arr_perm);
    function get_permutations($array1, $array2)
    {
        $result = '';
        foreach($array1 as $elem1)
        {
            foreach($array2 as $elem2)
            {
                $result[] = $elem1 . ' ' . $elem2;
            }
        }
        return $result;
    }
?>

Hello
The above example is correct. This can be alternatively done in this way also. Just try to add your knowledge.

Code:

---

$colors = array('red', 'b', 'g');
$animals = array('c', 'e', 'm');

foreach ($colors as $color) {
    foreach ($animals as $animal) {
        echo $color . " " . $animal . "<br />";
    }
}

---

Want any more help, then do post back.
