# opendir

(PHP 3, PHP 4 )

opendir -- open directory handle

## Description

resource opendir ( string path)

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

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. You can suppress the error output of opendir() by prepending `@' to the front of the function name.

Example 1. opendir() example
    <?php

    if ($dir = @opendir("/tmp")) {
      while (($file = readdir($dir)) !== false) {
        echo "$file\n";
      }
      closedir($dir);
    }

    ?>
