Returns a directory handle resource on success, or FALSE on failure.

If path is not a valid directory or the directory can not be opened due to permission restrictions or filesystem errors, opendir() returns FALSE and generates a PHP error of level E_WARNING. You can suppress the error output of opendir() by prepending '@' to the front of the function name.

Example #1 opendir() example

<?php
$dir 
"/etc/php5/";

// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
    if (
$dh opendir($dir)) {
        while ((
$file readdir($dh)) !== false) {
            echo 
"filename: $file : filetype: " filetype($dir $file) . "\n";
        }
        
closedir($dh);
    }
}
?>

filename: . : filetype: dir
filename: .. : filetype: dir
filename: apache : filetype: dir
filename: cgi : filetype: dir
