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);
}
[/code]
