opendirOpen directory handle

Description

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

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

Errors/Exceptions

Upon failure, an E_WARNING is emitted.

This may happen if path is not a valid directory, the directory can not be opened due to permission restrictions, or due to filesystem errors.

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
