ftp_quit() function in PHP

The ftp_quit() function in PHP is an alias to ftp_close(). It closes an FTP connection and cleans up resources associated with the connection.

Syntax

ftp_quit(connection);

Parameters

• connection − The FTP connection resource to close.

Return Value

The ftp_quit() function returns TRUE on success or FALSE on failure.

Example

The following example demonstrates connecting to an FTP server, performing some operations, and then properly closing the connection −

<?php
    $ftp_server = "ftp.example.com";
    $ftp_user = "kevin";
    $ftp_pass = "tywg61gh";
    
    // Establish FTP connection
    $con = ftp_connect($ftp_server);
    $res = ftp_login($con, $ftp_user, $ftp_pass);
    
    if ($res) {
        echo "Connected successfully<br>";
        
        // Change to demo directory
        ftp_chdir($con, 'demo');
        echo "Current directory: " . ftp_pwd($con) . "<br>";
        
        // Move up one directory
        if (ftp_cdup($con)) {
            echo "Directory changed!<br>";
        } else {
            echo "Directory change not successful!<br>";
        }
        
        echo "Current directory: " . ftp_pwd($con) . "<br>";
        
        // Close the connection
        if (ftp_quit($con)) {
            echo "Connection closed successfully<br>";
        }
    } else {
        echo "Connection failed<br>";
    }
?>

Connected successfully
Current directory: /demo
Directory changed!
Current directory: /
Connection closed successfully

Key Points

• ftp_quit() and ftp_close() are functionally identical

• Always close FTP connections to free up resources

• Returns TRUE if the connection was successfully closed

Conclusion

The ftp_quit() function provides a clean way to close FTP connections. It's essential for proper resource management and should be called after completing FTP operations to ensure connections are properly terminated.
