Thanks to h3 at valleyfield dot net

Same function with some minor changes and comments added

FTP function checks if a directory exists

<?php
function ftp_is_dir( $dir ) {
    global $ftpcon;
    // get current directory
    $original_directory = ftp_pwd( $ftpcon );
    // test if you can change directory to $dir
    // suppress errors in case $dir is not a file or not a directory
    if ( @ftp_chdir( $ftpcon, $dir ) ) {
        // If it is a directory, then change the directory back to the original directory
        ftp_chdir( $ftpcon, $original_directory );
        return true;
    } 
    else {
        return false;
    }        
} 
?>

Works like the other functions in this page's notes, but this one doesn't make use of a global FTP connection, so it takes parameters like the other functions in the extension

<?php
function ftp_directory_exists($ftp, $dir)
{
    // Get the current working directory
    $origin = ftp_pwd($ftp);
    
    // Attempt to change directory, suppress errors
    if (@ftp_chdir($ftp, $dir)) 
    {
        // If the directory exists, set back to origin
        ftp_chdir($ftp, $origin);    
        return true;
    }

    // Directory does not exist
    return false;
}
?>
