# opendir

(PHP 4, PHP 5)

opendir — Open directory handle

### Description

resource opendir ( string `$path` [, resource `$context` ] )

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

### Parameters

`path`

  The directory path that is to be opened

`context`

  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.

### Changelog

Version | Description
--- | ---
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

### Examples

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);
}
}
?>`

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
