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;
}
?>
