PHP Foreach Loop and DOMNodeList

Question

I am trying to determine the end of a foreach loop that is seeded with a collection of DOMNodeList. Currently, I am using a for loop would like to avoid having a \'magic\'

Answer 1

You can use:

$cols->length

To retrieve the number of items in a DOMNodeList.

See http://php.net/manual/en/class.domnodelist.php

Edit: If you change you're code to this, you don't have to worry about the trailing comma, or the length:

$output = array();
foreach ($cols as $item) {
   $output = iconv("UTF-8", "ASCII//IGNORE", $item->nodeValue);
   $output2 = trim($output);

   $output[] = '"' . $output2 . '"';
}
$outputstring = implode(',', $output);

Answer 2

$cols->length

Should give you the number of items in the list

for ($i = 0; $i < $cols->length; $i++) {

// ...

if ($i == $cols->length - 1) {
// last column
