问题描述

我在 FTP 上有一个具有动态文件名的文件.架构类似于:

I have a file on an FTP with a dynamic filename. The schema looks something like:

ABCD_2_EFGH_YYMMDD_YYMMDD_randomnumber_.TXT

日期 (YYMMDD) 反映前一天和当天，randomnumber 值是文件中记录的计数，并且每天都在变化.

The dates (YYMMDD) reflect the previous day and current day and the randomnumber value is a count of the records in the file and varies each day.

我正在尝试使用 PHP 检索文件，但在使用通配符名称时遇到问题.以下是代码示例:

I am attempting to retrieve the file using PHP but I am having trouble using a wildcard name. Here is a sample of the code:

<?php
$yesterday = strtotime('-1 day', time());
$today = strtotime('-0 day', time());
$local_file = "ABCD_2_EFGH__".date('Y-m-j', $yesterday).".txt";
$server_file = "ABCD_2_EFGH_".date('ymd', $yesterday)."_".date('ymd', $today)."_*.txt";

$conn_id = ftp_connect(ftpaddress);
$login_result = ftp_login($conn_id, 'username', 'password');
ftp_chdir($conn_id, 'subdirectory name');
ftp_get($conn_id, $local_file, $server_file, FTP_BINARY);
?>

运行此代码时出现以下错误:

When running this code i get the following error:

ftp_get() 期望参数 3 是有效路径

ftp_get() expects parameter 3 to be a valid path

我也尝试将 glob() 用于 $server_file 并收到相同的错误.

I have also tried using glob() for $server_file and receive the same error.

有谁知道如何在 ftp_get() 中使用动态文件名?

Does anyone know how to use dynamic filenames with ftp_get()?

推荐答案

您可以使用带有模式的 ftp_nlist 从 ftp 文件夹中检索文件名.然后在循环中使用 ftp_get

You can use ftp_nlist with pattern to retreive file names from ftp folder. And then use ftp_get in loop

$fileList = ftp_nlist($conn_id, 'subdirectory_name/file_prefix_*.txt');

for ($i = 0; $i < count($fileList); $i++) {
    $localFile = tempnam(sys_get_temp_dir(), 'ftp_in');
    if (ftp_get($conn_id, $localFile, $fileList[$i], FTP_BINARY)){
      //do something
    }
}
