试试这个解决方案:
// the server you wish to connect to - you can also use the server ip ex. 107.23.17.20
$ftp_server = "ftp.example.com";
// set up a connection to the server we chose or die and show an error
$conn_id = ftp_connect($ftp_server) or die("Couldn't connect to $ftp_server");
ftp_login($conn_id,"ftpserver_username","ftpserver_password");
// check if a file exist
$path = "/SERVER_FOLDER/"; //the path where the file is located
$file = "file.html"; //the file you are looking for
$check_file_exist = $path.$file; //combine string for easy use
$contents_on_server = ftp_nlist($conn_id, $path); //Returns an array of filenames from the specified directory on success or FALSE on error.
// Test if file is in the ftp_nlist array
if (in_array($check_file_exist, $contents_on_server))
{
echo "<br>";
echo "I found ".$check_file_exist." in directory : ".$path;
}
else
{
echo "<br>";
echo $check_file_exist." not found in directory : ".$path;
};
// output $contents_on_server, shows all the files it found, helps for debugging, you can use print_r() as well
var_dump($contents_on_server);
// remember to always close your ftp connection
ftp_close($conn_id);

可能的问题/解决方案
首先:您是否验证了文件的权限?
第二:使用 ftp_get() ( https://www.php.net/manual/en/function.ftp-get.php ),这将是最方便的。

我已经在我的本地检查了你的代码。这是工作文件。我已经检查了我的本地文件路径。
我认为你的路径有问题。确认路径是否正确。
并检查应该有 755 或 777 的文件权限。
这是我的代码
<?php
$path = 'C:\xampp\htdocs\test\XSCAssets\idea\157406374721215421965dd24e83bf2e7.png';
if (file_exists($path)) {
$tbody = '<td>DATA ON SERVER</td>';
} else {
$tbody = '<td>NO DATA</td>';
}
echo $tbody;
?>
