PHP Foreach Loop and DOMNodeList Collection

[Pro100]

I am trying to see if I can convert a for loop to a foreach loop. Reason: Because I would like to make this code more generic and stay away from magic numbers. Although I know the numbers of column in the dataset, I would prefer to make the code more generic. I have tried using the end() and next() functions to try and detect the last element in the DOMNodeList, but I am not having success.My final output will be in a CSV format with enclosures like so,"Value 1","Value 2","Value 3","Value 4","Value 5","Value 6","Value 7","Value 8"Here is my original for loop:\[code\] $cols = $row->getElementsByTagName("td"); $printData = http://stackoverflow.com/questions/2018059/true; // Throw away the header row if ($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 . "\"" . ","; } }\[/code\]
