trouble with a loop?

while loop

[Matthew1980]

Hello people of webmaster world,

Could anyone shed some light on my problem?

$images_across_cell = "5";

//create array and populate

$img = array('1','2','3','4','5','6','7','8','9','10');

//start building html block code

$data = "<ul>";

//loop through each instance of array

foreach($img as $display_img)
{
$data .= "<li>".$display_img."</li>";

}

//close html block off

$data .= "</ul>";

//$data ready to echo to screen
echo $data;
?>

Each number represents an image, i would like to specify '5' images populating each <li> tag
before the loop starts again, creates the next <li> tag and fills with another '5' images until
the array is exhausted, then exits the loop and closes the <ul> part too. So this example should
get 2 rows of <li></li>tags and opening and closing <ul> tags'

Im just not sure how to do it!

Obviously, if there are no pictures there nothing gets created, but that is just going to be an if
clause..

Thank you in advance.

Matthew

This should get you started
review ARRAY_CHUNK() [us2.php.net]

<?php
// example
$arr=array( '1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12' );
$chunk= array_chunk($arr,5);
print_r($chunk);
?>

If you try my above example it will result in two chunks of "5 numbers" and a residual chunk of "2 numbers"

I don't know if this is what you exactly want..but you can try this one out

$images_across_cell = "5";

//create array and populate

$img = array('1','2','3','4','5','6','7','8','9','10','11','12');

$n=12; //no of elements in array

//start building html block code

$data = "<ul>";

//loop through each instance of array
$x=0;
while($x<$n)
{
$data .= "<li>";
$y = $x;
while($y<$x+$images_across_cell)
{
if ($y > $n-1)
break;

$data .= $img[$y];
$y++;
}
$data .= "</li>";
$x = $y;
}
//close html block off

$data .= "</ul>";

//$data ready to echo to screen
echo $data;

Hello Ayushchd,

Thanks for the help, your code did just the thing i wanted, only altered a little bit to help if 'fit' into where i needed it.

Cheers,
