PHP opendir

PHP original manual for opendir [ show | php.net ]

opendir

(PHP 4, PHP 5, PHP 7)

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
