Putting 'foreach' into an array

[Jragon]

Hey guys,

 

I was wondering how i could put a foreach statement into varible or array.

 

My code:

<?php

function permute($array,$positions,&$perms,$previous = null) {
  if($positions > 0) {
if(!isset($previous)) {
  $previous = array();
}

    foreach($array as $element) {
  $tempPrevious = $previous;
  $tempPrevious[] = $element;
  permute($array,$positions-1,$perms,$tempPrevious);
}
  } else {
    $perms[] = $previous;
  }
}

$perms = array();
$letters = array('a','b','c','d', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'x');
$numofletters = 3;

permute($letters, $numofletters, $perms);

foreach($perms as $key => $row){
    foreach($row as $letter){
        echo $letter;
    }
    echo '<br />';
}
?>

 

It creates random letter arrangements and i want to put those letters in to a array so that it would look like this:

$1 = array('aaa', 'aab' ECT)

 

and then i want to put it in to a while loop and MD5 it so it will look somthing like this:

while($letterarray){
    echo $letterarray;
    echo md5($letterarry);
}

 

so in the end it will out put somthing like this:

word
md5ed word
word
md5ed word
word
md5ed word
word
md5ed word
word
md5ed word
word
md5ed word
word
md5ed word
word
md5ed word

 

Any help would be much appreciated

 

Thanks
