Hey there,

I've had some experience working with the ftp_get_option() function in PHP, so I'll try my best to help you out. This function is used to retrieve various options of an FTP connection. It allows you to fetch information regarding the current FTP session.

Here's a simple example to demonstrate the usage of ftp_get_option():

php
// Connect to FTP server

$ftpServer = 'ftp.example.com';

$ftpUser = 'your_username';

$ftpPass = 'your_password';

$ftpConnection = ftp_connect($ftpServer);

ftp_login($ftpConnection, $ftpUser, $ftpPass);



// Get FTP option

$optionValue = ftp_get_option($ftpConnection, FTP_TIMEOUT_SEC);

echo "Current FTP timeout value: " . $optionValue;



// Close FTP connection

ftp_close($ftpConnection);

In this example, we establish a connection to the FTP server and log in using the ftp_connect() and ftp_login() functions, respectively. Then, we call ftp_get_option() to retrieve the value of the FTP_TIMEOUT_SEC option, which represents the timeout duration for FTP operations in seconds. The returned value is then displayed to the user.

It's important to note that the options you can retrieve using ftp_get_option() vary depending on your FTP server configuration. Some common options include FTP_TIMEOUT_SEC, FTP_AUTOSEEK, and FTP_USEPASVADDRESS.

I hope this clarifies the usage of ftp_get_option() for you. If you have any further questions, feel free to ask!

Hey there,

I've used the ftp_get_option() function in PHP several times, so I'm happy to share my experience with you. This function allows you to retrieve specific options or settings related to an active FTP connection.

To give you an idea of how it works, here's an example:


// Connect to FTP server

$ftpServer = 'ftp.example.com';

$ftpUser = 'your_username';

$ftpPass = 'your_password';

$conn = ftp_connect($ftpServer);

ftp_login($conn, $ftpUser, $ftpPass);



// Get FTP option - PASV mode

$pasvMode = ftp_get_option($conn, FTP_USEPASVADDRESS);

echo "PASV mode: " . ($pasvMode ? "Enabled" : "Disabled");



// Get FTP option - Transfer mode

$transferMode = ftp_get_option($conn, FTP_TRANSFER_MODE);

$modeName = ($transferMode === FTP_ASCII) ? "ASCII" : "Binary";

echo "Transfer mode: " . $modeName;



// Close FTP connection

ftp_close($conn);

In this example, after establishing a connection using ftp_connect() and logging in with ftp_login(), we use ftp_get_option() to retrieve two different options.

Firstly, we fetch the value of FTP_USEPASVADDRESS, which determines whether the FTP connection uses the passive (PASV) mode or not. This mode is beneficial for servers behind firewalls.

Secondly, we retrieve the FTP_TRANSFER_MODE setting, which specifies the transfer mode for file transfers. The value returned can be either FTP_ASCII or FTP_BINARY, indicating ASCII or binary transfer modes, respectively.

By using these options, you can gather information about the FTP connection and tailor your operations accordingly.

If you have any further queries, feel free to ask!
