Yii Files

The package provides useful methods to manage files and directories.

Requirements

• PHP 7.4 or higher.

Installation

The package could be installed with composer:

composer require yiisoft/files --prefer-dist

FileHelper usage

FileHelper provides static methods you can use for various filesystem-related operations.

Working with directories

Ensure a directory exists:

use \Yiisoft\Files\FileHelper;

$directory = '/path/to/dir';
FileHelper::ensureDirectory($directory);

Ensure a directory exists, and permission specified is set:

use \Yiisoft\Files\FileHelper;

$directory = '/path/to/dir';
FileHelper::ensureDirectory($directory, 0775);

Remove a directory:

use \Yiisoft\Files\FileHelper;

$directory = '/path/to/dir';
FileHelper::removeDirectory($directory);

Remove everything within a directory but not directory itself:

use \Yiisoft\Files\FileHelper;

$directory = '/path/to/dir';
FileHelper::clearDirectory($directory);

Check if directory is empty:

use \Yiisoft\Files\FileHelper;

$directory = '/path/to/dir';
FileHelper::isEmptyDirectory($directory);

Copy directory:

use \Yiisoft\Files\FileHelper;

$source = '/path/to/source';
$destination = '/path/to/destination';
FileHelper::copyDirectory($source, $destination);

Additional options could be specified as third argument such as filter or copyEmptyDirectories. Check method phpdoc for a full list of options.

Search

Searching for files:

use \Yiisoft\Files\FileHelper;
use Yiisoft\Files\PathMatcher\PathMatcher;

$files = FileHelper::findFiles('/path/to/where/to/search', [
    'filter' => (new PathMatcher())->only('**.png', '**.jpg')->except('**/logo.png'),
]);

Searching for directories:

use \Yiisoft\Files\FileHelper;
use Yiisoft\Files\PathMatcher\PathMatcher;

$directories = FileHelper::findDirectories('/path/to/where/to/search', [
    'filter' => (new PathMatcher())->except('**meta'),
]);

Other

Open a file. Same as PHP's fopen() but throwing exceptions.

use \Yiisoft\Files\FileHelper;

$handler = FileHelper::openFile('/path/to/file', 'rb');

Get last modified time for a directory or file:

use \Yiisoft\Files\FileHelper;

$directory = '/path/to/dir';
$time = FileHelper::lastModifiedTime($directory);

The method is different from PHP's filemtime() because it actually scans a directory and selects the largest modification time from all files.

Remove a file or symlink:

use \Yiisoft\Files\FileHelper;

$file = '/path/to/file.txt';
FileHelper::unlink($file);

Normalize a path:

use \Yiisoft\Files\FileHelper;

$path = '/home/samdark/./test/..///dev\yii/';
echo FileHelper::normalizePath($path);
// outputs:
// /home/samdark/dev/yii
