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;
}
?>
