Outputting array contents as nested list in PHP

Question

I have the array array ( [0] => array(1,2,3,4,5) [1] => array(6,7,8,9,10)) and I would like to display it like this:

Answer 1

Here is another way to do this (demo here):

 elements per 

$aElements = 2;    

$totalElems = count($tab);    

//open the list
echo "
";

for($i=0;$i<$totalElems;$i++){

    if($i != 0 && ($i%$aElements) == 0){ //check if I'm in the nTh element.
        echo "
"; //if so, close curr 
 and open another 
 element
    }

    //print  elem inside the 

    echo "".$tab[$i]."";
}

//close the list
echo "
";

?>

Tip explanation: $i%n (mod) equals 0 when $i is the nTh element (remainder of division is 0)

EDITED: made a general solution
