This code was not written by me, but it almost does what you want it to. I hope that you can do the part that is missing, because this sounds like homework, so you should be doing it yourself.

<?
\$yourArr;
\$pArr;
\$n;

perm(array("I ", "am ", "not ", "sure "));

function PrintPerm() {
global \$yourArr,\$pArr,\$n;

for (\$i=1; \$i <= \$n; \$i++)
echo \$yourArr[\$pArr[\$i]-1];
echo "<br>";

return;
}

function swapThem(\$i,\$j) {
global \$pArr;

\$temp = \$pArr[\$i];
\$pArr[\$i] = \$pArr[\$j];
\$pArr[\$j] = \$temp;
}

function NextPerm() {
global \$pArr,\$n;

\$k = \$n-1;
while (\$pArr[\$k] > \$pArr[\$k+1]) \$k--;
if (\$k == 0) return(0);
else
{
\$j = \$n;
while (\$pArr[\$k] > \$pArr[\$j]) \$j--;
swapThem(\$j,\$k);
\$r = \$n;
\$s = \$k+1;
while (\$r > \$s)
{
swapThem(\$r,\$s);
\$r--;
\$s++;
}
}
PrintPerm();
return(1);
}

function perm(\$array) {
global \$yourArr,\$pArr,\$n;
\$yourArr=\$array;

\$n = count(\$yourArr);

for (\$i=0; \$i <= \$n; \$i++) \$pArr[\$i]=\$i; //The permutation array.

//Print the array values
PrintPerm();
while (NextPerm()); //Permute and print
}
?>

thats all good except for 3 undefined variable errors....It shouldn't have..

\$yourArr;
\$pArr;
\$n;

..up the top because it is not a class, therefore they do not need to be predefined and it works perfectly without them.

Sounds good, but you shouldn't be getting errors anyway (I don't).
