我使用以下
PHP代码列出当前目录下的所有文件和文件夹：
<?PHP $dirname = "."; $dir = opendir($dirname); while(false != ($file = readdir($dir))) { if(($file != ".") and ($file != "..") and ($file != "index.PHP")) { echo("<a href='$file'>$file</a> <br />"); } } ?>
问题是列表不按字母顺序排列(也许按创建日期排序？我不确定).
我如何确保按字母顺序排列？
manual清楚地说：
原文链接：https://www.f2er.com/php/140046.htmlreaddir
Returns the filename of the next file from the directory. The filenames are returned in the order in which they are stored by the filesystem.
您可以做的是将文件存储在数组中,对其进行排序,然后将其打印为：
$files = array();
$dir = opendir('.'); // open the cwd..also do an err check.
while(false != ($file = readdir($dir))) {
if(($file != ".") and ($file != "..") and ($file != "index.PHP")) {
$files[] = $file; // put in array.
}
}
natsort($files); // sort.
// print.
foreach($files as $file) {
echo("<a href='$file'>$file</a> <br />\n");
}
