Open directory handle (PHP 4, PHP 5)
resource opendir ( string path [, resource context] )

Opens up a directory handle to be used in subsequent closedir(), readdir(), and rewinddir() calls.



The directory path that is to be opened


For a description of the context parameter, refer to the streams section of the manual.

Return Values

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.


5.0.0 path supports the ftp:// URL wrapper.
4.3.0 path can also be any URL which supports directory listing, however only the file:// URL wrapper supports this in PHP 4


Example 507. opendir() example

= "/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) {
"filename: $file : filetype: " . filetype($dir . $file) . "\n";

The above example will output something similar to:

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