Here is my first cut at the problem. It is probably not the most
optimal
solution in terms of algorithmic complexity and it could also do
without
the use of global vars and such, but it should give you some ideas.
[code]
$arr = array('word1', 'word2', 'word3');
$lowerBound = 1;
$upperBound = pow(2, count($arr)) - 1;
for ($index = $lowerBound; $index <= $upperBound; ++$index) {
$bitString = str_pad(decbin($index), count($arr), 0,
STR_PAD_LEFT);
echo showValues($bitString) . "<br>";
}
function showValues($bitString) {
global $arr;
$outputStringArray = array();
for ($pos = 0; $pos < strlen($bitString); ++$pos) {
if ($bitString[$pos]) {
$outputStringArray[] = $arr[$pos];
}
}
return implode(' ', $outputStringArray);
}

Sure Chris.
$words = array("word1","word2","word3");
I want this:
$result = array(
"word1",
"word2",
"word3",
"word1 word2",
"word1 word3",
"word2 word1",
"word2 word3",
"word3 word1",
"word3 word2",
"word1,word2,word3"
);
Thanks - MD

Could you post a sample of what you have and what you want to end
up with?
It'll be easier for us to work out rather than guess at what
you're
trying to do.
