我在使用laravel的时候,需要对一个目录下面的文件进行筛选,例如只想要**.txt**类型的文件。
一种方法是:
Storage::disk(‘c-drive‘)->allFiles();
得到文件数组,然后再遍历进行过滤筛选,这种对于文件较多不是很方便,而且比较慢;
第二种方式:使用php自带的glob函数,进行直接筛选;
// List files $files=glob($path.$match); foreach($files as $file){ $list[]=substr($file,strrpos($file,"/")+1); }
速度快,但是不是很灵活;
第三种方式,比较推荐,使用symfony的Finder包,这个包Laravel本来就自带了,所以直接上方法:
use Symfony\Component\Finder\Finder; $finder = new Finder(); $finder->files()->in(__DIR__); foreach ($finder as $file) { // dumps the absolute path var_dump($file->getRealPath()); // dumps the relative path to the file, omitting the filename var_dump($file->getRelativePath()); // dumps the relative path to the file var_dump($file->getRelativePathname()); } #根据时间,名称来筛选文件 $finder->files()->name(‘*.php‘); use Symfony\Component\Finder\Finder; $s3 = new \Zend_Service_Amazon_S3($key, $secret); $s3->registerStreamWrapper(‘s3‘); $finder = new Finder(); $finder->name(‘photos*‘)->size(‘< 100K‘)->date(‘since 1 hour ago‘); foreach ($finder->in(‘s3://bucket-name‘) as $file) { // ... do something with the file }
获取文件真实路径和文件内容:
dd($file, $file->getRealPath(), $file->getContents());
另外,还可以通过函数直接将文件内容读到一个数组里面去:
实际应用:
1 public function renameFiles(Request $request) 2 { 3 $validator = Validator::make($request->all(), [ 4 ‘driver‘ => ‘required|in:c-drive, d-drive, e-drive, f-drive‘, 5 ‘dir‘ => ‘required|string|max:1024‘, 6 ‘patten‘ => ‘required|string|max:1024‘, 7 ‘extension‘ => ‘required|string|max:1024‘, 8 ]); 9 10 if ($validator->fails()) { 11 return $this->outPutJson($validator->errors()); 12 } 13 14 $dir = Storage::disk($driver)->path($dir); 15 $finder = new Finder(); 16 $txt = iterator_to_array($finder->files()->name(‘*\.txt‘)- >in($dir)); 17 $names = file(head($txt)->getRealPath(), FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES); 18 $needs = Finder::create()->files()->name($patten)->in($dir)->depth(0); 19 20 foreach ($needs as $key => $value) { 21 $a[] = $value->getRealPath(); 22 } 23 natsort($a); 24 foreach (array_values($a) as $key => $value) { 25 if (isset($names[$key])) { 26 $res = rename($value, str_replace([‘ ‘, ‘?‘, ‘?‘, ‘,‘, ‘,‘, ‘。‘, ‘,‘], ‘‘, $dir . ‘/‘ . $names[$key] . $extension)); 27 } else { 28 dd(‘这个名字及之后的文件名称未做更改:‘ . $value . ‘请注意‘); 29 } 30 } 31 }
