The closedir Function
The closedir function closes a directory handle that was previously opened by the opendir function. This frees the system resources associated with the handle.
Syntax
closedir(resource $dir_handle): void
Example
Basic usage with opendir:
<?php
$dir = opendir('/path/to/directory');
if ($dir) {
// Working with the directory
closedir($dir); // Closing the handle
}
?>
Always close the handle after finishing work with the directory.
Example
Usage in a try-finally block:
<?php
$dir = opendir('/path/to/directory');
try {
// Working with the directory
} finally {
if (is_resource($dir)) {
closedir($dir);
}
}
?>
This approach guarantees that the handle will be closed even if an exception occurs.
Example
Closing a handle after scandir:
<?php
$dir = opendir('.');
$files = scandir($dir);
closedir($dir);
print_r($files);
?>
