PHP Foreach Loop and DOMNodeList

[Anastasia]

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' number there. I do know there are only going to be 8 columns, but I would like the code me generic for other applications.Is it possible to convert this to a Foreach loop? I have tried the end() and next() functions, but they are not returning any data and I suspect that they only work on arrays and not this DOMNodeList collection.The code is building a CSV file without the trailing ','Current output is:"Value 1","Value 2","Value 3","Value 4","Value 5","Value 6","Value 7","Value 8" Here is an example of code:\[code\]$cols = $row->getElementsByTagName("td");$printData = http://stackoverflow.com/questions/2016685/true;// Throw away the header rowif ($isFirst && $printData) { $isFirst = false; continue;}for ($i = 0; $i <= 8; $i++) { $output = iconv("UTF-8", "ASCII//IGNORE", $cols->item($i)->nodeValue); $output2 = trim($output); if ($i == 8) { // Last Column echo "\"" . $output2 . "\"" . "\n"; } else { echo "\"" . $output2 . "\"" . ","; }}\[/code\]
