Ftp_close()

Understanding the PHP Function ftp_close()

The ftp_close() function is a PHP built-in function that is used to close an FTP connection. The function takes a connection identifier returned by the ftp_connect() function as its parameter and returns a boolean value. If the function is successful in closing the connection, it returns true. Otherwise, it returns false.

Syntax of ftp_close()

The syntax of the ftp_close() function is as follows:

bool ftp_close ( resource $ftp_stream )

The ftp_close() function takes one parameter: ftp_stream. The ftp_stream parameter is the connection identifier returned by the ftp_connect() function.

Usage of ftp_close()

To use the ftp_close() function, you first need to establish a connection to the FTP server using the ftp_connect() function. Here's an example:

<?php

// Set up an FTP connection
$conn = ftp_connect('ftp.example.com');

// Login with your FTP credentials
ftp_login($conn, 'username', 'password');

// Do some FTP operations...

// Close the connection
ftp_close($conn);

In this example, we establish a connection to the FTP server using the ftp_connect() function. Then we log in using our FTP credentials using the ftp_login() function. Finally, we perform some FTP operations and close the connection using the ftp_close() function.

Error handling in ftp_close()

It's important to handle errors properly when using the ftp_close() function. If the function returns false, it means that the connection couldn't be closed for some reason. Here's an example of how to handle errors:

<?php

if (ftp_close($conn) === false) {
    echo "Failed to close the connection.\n";
} else {
    echo "Connection closed successfully.\n";
}

In this example, we check the return value of the ftp_close() function. If it's false, we display an error message; otherwise, we display a success message.
