permutations of a multi-dimensional array

[centenial]

Hi,

 

I have a multidimensional array that looks like this

 

s

t

r

1

2

3

 

I want to print out the possible permutations of this into one string. Something like this:

 

str

st3

s2r

s23

1tr

1t3

123

 

Can anyone think of a way to do this?

 

Much appreciated,

Here's a quick and dirty solution.

 

<?php

$data = array ('s', 't', 'r', '1', '2', '3');

foreach($data as $char1)
{
    foreach($data as $char2)
    {
        if ($char2 != $char1)
        {
            foreach($data as $char3)
            {
                if ($char3!=$char1 && $char3!=$char2)
                {
                    echo "{$char1}{$char2}{$char3}<br />\n";
                }
            }
        }
    }
}

?>
