Hi all,

I'm looking for some efficient php code to do the following:

Consider an input string of "one two three four" (any numer of words delimited by spaces).

I would like to output all possible combinations of phrases and words in that sentance e.g. :

one two three four
one two three
one two
one
two three four
three four
three
four

Would like to then put them in a string comma seperated (e.g. one two three four, one two three, one two, one, two three four,...)

Doesn't have to be in that order but any help on this much appreciated - driving me mad!

Cheers
David

Wrote this, output what you were hoping for, added the vardump at the bottom to show what it looks like before imploding.
<?php

$test = "one two three four";
$rescount = 1;
$results = array();
$result[] = $test;

$words = explode(' ',$test);
$wordc = count($words);

for( $i=0; $i<$wordc; $i++ ) {
	for( $j=$wordc; $j>0; $j-- ) {
		$results[$rescount] = '';
		for( $k=$i; $k<$j; $k++ ) {
			$results[$rescount] .= ' '. $words[$k];
		}
		if( !empty($results[$rescount]) ) $rescount++;
	}
}
if( empty($results[$rescount]) ) unset($results[$rescount]);

echo implode(',',$results);

echo '<pre>';
var_dump($results);
echo '</pre>';
