opendir
(PHP 4, PHP 5)
opendir — Open directory handle
Description
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

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
