[Resolved] readdir() problems

[webchef]

this is driving me nuts.. as far as i can see the code should be working, but for some reason it doesn't.

// Let's see if $page is odd
$odd_flag = $page & 1;

// Set location of pdf's and then open directory
$dir = 'pdf';
$d = opendir($dir);

while (false !== ($file = readdir($d))) {
	if ($file == "." || $file == "..") continue; 
	// Let's see if this is a file or a directory
    if (is_file($file)) {
        // Check if $page is even or odd
        if ($odd_flag) {
            // $page should precede the underscore
            if (preg_match('/' . $page . '\_[02468]+\.pdf/', $file)) {
                $rString = "&link=".$file."#viewrect=".$left.",".$top.",113.2,113.2";
                echo "check 1 <br>";
            }
        } else {
            //$page should follow the underscore
            if (preg_match('/[13579]+\_' . $page . '\.pdf/', $file)) {
                $rString = "&link=".$file."#viewrect=".$left.",".$top.",113.2,113.2";	                

                echo "check 2 <br>";
            }
        }
    } else {
    	echo "NO GO! <br>";
    }
}

// Close the directory
closedir($d);

The script always straight to the NO GO! else statement. $file never gets populated. i don't know why.

thanks in advance for any help

Hi,

try if it works replacing
if (is_file($file)) {
by
if (is_file("$dir/$file")) {

You might need to use a backslash if the web server is running under Windows.
