opendir
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 of level E_WARNING. You can suppress the error output of opendir() by prepending '@' to the front of the function name.
Example 1. opendir() example
<?php
$dir = "/tmp/";
// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
echo "filename: $file : filetype: " . filetype($dir . $file) . "\n";
}
closedir($dh);
}
}
?>
As of PHP 4.3.0 path can also be any URL which supports directory listing, however only the file:// URL wrapper supports this in PHP 4.3. As of PHP 5.0.0, support for the ftp:// URL wrapper is included as well.
