php noob在这里-我将这个脚本拼凑在一起,以显示带有opendir的文件夹中的图像列表,但是我无法弄清楚如何(或在哪里)按字母顺序对数组进行排序
<?php // opens images folder if ($handle = opendir('Images')) { while (false !== ($file = readdir($handle))) { // strips files extensions $crap = array(".jpg", ".jpeg", ".JPG", ".JPEG", ".png", ".PNG", ".gif", ".GIF", ".bmp", ".BMP", "_", "-"); $newstring = str_replace($crap, " ", $file ); //asort($file, SORT_NUMERIC); - doesnt work :( // hides folders, writes out ul of images and thumbnails from two folders if ($file != "." && $file != ".." && $file != "index.php" && $file != "Thumbnails") { echo "<li><a href=\"Images/$file\" class=\"thickbox\" rel=\"gallery\" title=\"$newstring\"><img src=\"Images/Thumbnails/$file\" alt=\"$newstring\" width=\"300\" </a></li>\n";} } closedir($handle); } ?>
任何建议或指针将不胜感激!
您需要先将文件读入数组,然后才能对它们进行排序。这个怎么样?
<?php $dirFiles = array(); // opens images folder if ($handle = opendir('Images')) { while (false !== ($file = readdir($handle))) { // strips files extensions $crap = array(".jpg", ".jpeg", ".JPG", ".JPEG", ".png", ".PNG", ".gif", ".GIF", ".bmp", ".BMP", "_", "-"); $newstring = str_replace($crap, " ", $file ); //asort($file, SORT_NUMERIC); - doesnt work :( // hides folders, writes out ul of images and thumbnails from two folders if ($file != "." && $file != ".." && $file != "index.php" && $file != "Thumbnails") { $dirFiles[] = $file; } } closedir($handle); } sort($dirFiles); foreach($dirFiles as $file) { echo "<li><a href=\"Images/$file\" class=\"thickbox\" rel=\"gallery\" title=\"$newstring\"><img src=\"Images/Thumbnails/$file\" alt=\"$newstring\" width=\"300\" </a></li>\n"; } ?>
编辑:这与您要的内容无关,但是您也可以使用pathinfo()函数对文件扩展名进行更通用的处理。然后,您不需要扩展的硬编码数组,就可以删除任何扩展。
