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=\"thick@R_290_2419@\" 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。
