----

if you want to sort array like this one
$aInt = array('1','2','3','4');
and you to have somethings like this 
1 --- 2
1 --- 3
1 --- 4
2 --- 3
2 --- 4
3 --- 4

you can do this like with 

$NumInt = count($aInt); 
for($j=0; $j<=$NumInt-1; $j++){        
        $first = $aInt[$j]; 
            for ($i=1; $i<=$NumInt-1-$j; $i++) { 
                echo $first." --- ".$aInt[$i+$j]."<br>"; 
            }      
}
