RE: [PHP] while loop: detect next loop?

When you have all your items in an array use implode to add a character in between every item. $str = implode($yourArray, $separator); This will add the separator to the end of each string except the last one.

There is a nice feature of a for loop, that I would like to replicate somehow within a while loop. The short question is this -- is there any way to detect if the while loop has one or more iterations remaining (after the current iteration) to go through, so that I can [for instance] add a comma or a newline or something to the text that is printed in the loop iteration? In a for loop I can do this: for ($c = 0; $c < sizeof($array); $c++) { $data_printed = $array[$c]; if ($c < sizeof($array) - 1) { $data_printed .= "\n "; } } I have a while loop like this: while ($row = mysql_fetch_assoc($result)) { $data_printed = "<file id=\"" . $row['file_id'] . "\">" . $row['file_name'] . "</file>"; } This prints things like this: <file id="1">somefile.txt</file><file id="2">otherfile.pdf</file> etc I do not want to blindly add a newline and some whitespace to EVERY iteration, because this is XML and the whitespace is significant (and this code will impact thousands of files), but I can't think of a clever way of adding the newline and whitespace to every iteration EXCEPT the last one.
