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;
}
?>
