check to see if a directory exists

[topcoder1]

given a path, I want to check to see if a directory exists, then create one if it doesn't.

dir(path) gives an error: [function.dir]: failed to open dir: Invalid argument .

Are there functions allow me to do all those?

thanks

try this

<?php
$dir = "path/to/folder";
if( !(file_exists($dir) && is_dir($dir)) )
{
mkdir($dir, 0700);
}
?>

PS file_exists check files and folders
