OK, this time I’ve revised my PHP code to show a sorted list of labels:
<?php $dirname = "."; # current directory $dir = opendir($dirname); $file_list = array(); $i = 0; while (false != ($file = readdir($dir))) { if (ereg(".html$", $file)) { $tag = substr($file, 0, strlen($file)-5); $file_list[$i] = "<li><a href='/labels/$file'>$tag</a>"; $i++; } } closedir($dir); natcasesort($file_list); ?> <h1>My Tags</h1> <ul> <?php foreach ($file_list as $file) echo($file); ?> </ul>
Not a big deal, but it does show a (probably) typical use of arrays in PHP. As a side note, the “foreach” construct in PHP is a bit different from the usual foreach in other languages. It’s usually something like “foreach (item in list)”, while in PHP it’s reversed: “foreach (list as item)”. I should also mention that I first tried the regular sort() function, but switched to natcasesort(), since a case-insensitive sort makes more sense here.
