Array issue

[gibigbig]

I have an array of image id's:

$all_images = array("33","44","46","100","120","600","907","1200","1239","1299","1305");

as an example and i have the current id of the page from the $_GET['imageid'], as so:

$imageid =  $_GET['imageid'];

what i would like to do is to somehow find a way to see choose the imageid in $all_images directly AFTER the $imageid value.

 

for example, if the

$imageid = 600;

then i would like to find a way to get the id right after this, "907"

(a "next" button)

any idea how i can do this?

Try this:

 

reset($counter);
$nextimage = null;
do {
  if (current($counter) == $_GET['imageid']) {
    if (next($counter)) {
      $nextimage = current($counter);
    } else {
      // At the end of the array
    }
    break;
  }
} while (next($counter));
if ($nextimage) {
  // We found the next image
} else {
  // Either the image we received isn't in the array or we're at the end of the array
}

This should work:

$all_images[array_search($imageid, $all_images)+1]

This should work:

$all_images[array_search($imageid, $all_images)+1]

 

A-ha, I knew there had to be that function, just couldn't find it

What happens when $imageid is the last element in the array?  You better check for boundary conditions...
