is_dir fails to see folder is folder not file !

[mojito]

inside admin directory is a folder called "hh" and a file callled admin.php both are being seen by the script below but "hh" is not being recognised as a folder with is_dir comming out as false ???

 

$dir="./admin/";
openFolder();
function openFolder () {
clearstatcache() ;
global $dir;
if (is_dir($dir)) {
//open catalog
$open = opendir($dir);
//check every file
while (false !== ($file = readdir($open))) {
	var_dump (is_dir($file));
	echo $file;
	}
}
}

you had "while (false !== ($file = readdir($open)))  ..." in your code there, is "!==" valid?  shouldn't it be just "!=" ?

!== checks the type as well as the value, that's fine.

seems the full directory path works more reliably, when I thought code either worked or didnt!

so where I had simply $file $dir.$file gives me the correct answer.

 

thanks and welcome any more interest.
