Array and keys combination

[bledileka]

Hello !
Im got this array :

$numra=array(1,2,3,4,5,6....); //x numbers, max 90

Well, now i want to find all the possible unique combinations of this keys, i came up with something but i got problems on distinguing combinations.
Example : 1 - 4 - 3 - 5 - 6 is equal to 1 - 4 - 3 - 6 - 5. I need to show only one of this two.

This is the code (a real mess ) :

$numra=array(1,2,3,4,5,6); //x numra mund te vendosen
$sas=count($numra);
for ($i=0;$i<=$sas;$i++) {
		$n2=$numra;
			$s2=count($n2);
				for ($j=$i+1;$j<=$s2;$j++) {
				if ($n2[$j]<>$numra[$i]) {
				$n3=$n2;
			    $s3=count($n3);
				for ($k=$i+2;$k<=$s3;$k++) {
				if (($n3[$k]<>$n2[$j]) & ($n3[$k]<>$numra[$i])) {	
				$n4=$n3;
			    $s4=count($n4);
				for ($l=$i+3;$l<=$s4;$l++) {
				if (($n4[$l]<>$n3[$k])&($n4[$l]<>$n2[$j])&($n4[$l]<>$numra[$i])) {
				$n5=$n4;
			    $s5=count($n5);
				for ($m=$i+4;$m<=$s5;$m++) {
				if (($n5[$m]<>$n4[$l])&($n5[$m]<>$n3[$k])&($n5[$m]<>$n2[$j])&($n5[$m]<>$numra[$i])) {
					if ((isset($n2[$j]))&(isset($n3[$k]))&(isset($n4[$l]))&(isset($n5[$m]))) {
					$xx=$numra[$i]+$n2[$j]+$n3[$k]+$n4[$l]+$n5[$m];
					$v[]=$xx;
					if (in_array($xx,$v)) {
					$tot++;
					echo $numra[$i]; echo " - ";echo $n2[$j];echo " - ";echo $n3[$k];echo " - ";echo $n4[$l];echo " - ";echo $n5[$m];echo "<br>";
					

}
}}}}}}}}
				
}}echo $tot." Kombinacione !";

Can anyone help me on this ???

Please read the documentation more frequently to avoid mistakes like :
[ul]
[li]using [link

http://php.net/manual/en/language.operators.bitwise.php

]Bitwise Operators[/url] instead of Logical Operators[/li]
[li]using a bunch of [tt]echo[/tt] statements instead of a single one[/li]
[/ul]
And please read some programming tips and tricks documentation too.
