我正忙于修复每次显示文件时都会显示点的错误。修复错误后，点不再显示，而是显示我上传的第一个文件。但是，当我想上传新文件时，它不显示。旧文件仍保留在那里（应显示两个文件）。我曾经Continue修复过显示的点。我的 PHP 代码：<?phpif ( empty( $_FILES['file'] ) ) {?><html> <head> </head> <body> <form action="" enctype="multipart/form-data" method="post"> <input name="file" type="file"/> <br> <input name="submit" type="submit" value="Upload uw album" /> </form> </body></html><?phpreturn;} else {?><html> <head> </head> <body> <form action="" enctype="multipart/form-data" method="post"> <input name="file" type="file"/> <br> <input name="submit" type="submit" value="Upload uw album" /> </form> </body></html><?php}// Connectiegegevens$ftp_server = "myserver";$ftp_user_name = "myuser";$ftp_user_pass = "mypass";$source_file = $_FILES['file']['tmp_name'];$destination_folder = "/public_html/wp/wp-content/plugins/AbonneerProgrammas/Albums";$destination_file = $destination_folder . "/" . basename($_FILES['file']['name']);$conn_id = ftp_connect($ftp_server);// login with username and password$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); ftp_pasv($conn_id, true); // check connectieif ((!$conn_id) || (!$login_result)) { echo "Het spijt ons, er is momenteel geen connectie met de server."; // echo "Attempted to connect to $ftp_server for user $ftp_user_name"; exit; } else { // echo "upload is gelukt";}// upload het bestand$upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY);// check upload status if (!$upload) { echo "Er is iets fout gegaan, excuses voor het ongemak";} else {// weergeef het bestand & download$contents = ftp_nlist($conn_id, $destination_folder); foreach ($contents as $mp3_url) { $filename = basename($mp3_url, ".mp3");// Dit zorgt ervoor dat de punten niet te zien zijn if($filename == "." && "..") { continue; print_r($filename); } }?>

您正在使用 foreach 循环来获取数据：
foreach ($contents as $mp3_url) {
$filename = basename($mp3_url, ".mp3");
// Dit zorgt ervoor dat de punten niet te zien zijn
if($filename == "." && "..") {
continue;
print_r($filename);
}
但是这样您只显示该循环最后一次迭代的结果：
<tr>
<td><?php echo "<a href='$mp3_url'>$filename</a>"; ?></td>
</tr>
尝试：
$filenames = [];
foreach ($contents as $mp3_url) {
// {...} your remaining code
$filenames[] = $mp3_url;
}
进而
foreach ($filenames as $filename) {
echo $filename;
}
将这些文件名存储在数组中而不是字符串中将使您能够迭代它们。
