gitbox 2025-06-03

When using PHP for FTP operations, you often need to know the directory path you are currently in. This is the purpose of this, and it can quickly return the working directory path in the current FTP session. This article will introduce in detail how to use the ftp_pwd function, and use sample code to help you quickly understand how to obtain the current FTP directory.

What is the ftp_pwd function?

ftp_pwd is a built-in function in PHP to get the working directory of the current FTP connection. The working directory is the directory that is operating in the current session, similar to the "current folder" in the local system.

The function definition is as follows:

 string ftp_pwd ( resource $ftp_stream )

  • $ftp_stream : FTP connection resource, obtained after creation by functions such as ftp_connect and ftp_login .

  • The return value is a string that indicates the current working directory path.

Steps to use the ftp_pwd function

  1. Connect to the FTP server <br> Use ftp_connect to establish a connection.

  2. Log in to the FTP server <br> Use ftp_login for authentication.

  3. Call ftp_pwd to get the current directory <br> Directly call the ftp_pwd function to get the path.

  4. Close the connection <br> Use ftp_close to end the connection.

Code Example

 <?php
// connect FTP server
$ftp_server = "gitbox.net";
$ftp_user = "your_username";
$ftp_pass = "your_password";

$conn_id = ftp_connect($ftp_server);

if (!$conn_id) {
    die("无法connect到 FTP server $ftp_server");
}

// Log in FTP
if (!ftp_login($conn_id, $ftp_user, $ftp_pass)) {
    ftp_close($conn_id);
    die("FTP Log in失败");
}

// Get the current directory path
$current_dir = ftp_pwd($conn_id);

if ($current_dir !== false) {
    echo "current FTP The directory path is： " . $current_dir;
} else {
    echo "Get the current directory path失败";
}

// 关闭connect
ftp_close($conn_id);
?>

In this example, the code first connects to the FTP server gitbox.net and then logs in. After logging in successfully, get the current directory path through the ftp_pwd function and print it out.

Frequently Asked Questions and Precautions

  • Make sure to call ftp_pwd after logging in successfully

  • FTP server support <br> The vast majority of FTP servers support PWD commands, so ftp_pwd is usually very compatible.

  • Connecting resources is valid <br> Ensure that the connection resources passed in ftp_pwd are valid and active.

Summarize

ftp_pwd is a very practical function that can help you quickly obtain the directory path of the current FTP session, making it easier to determine the working directory during subsequent file operations. Mastering the use of ftp_pwd can make you more easily perform FTP-related development.
