In Laravel, how can I obtain a list of all files in a public folder?
提问by kant312
I'd like to automatically generate a list of all images in my public folder, but I cannot seem to find any object that could help me do this.
我想自动生成公共文件夹中所有图像的列表，但似乎找不到任何可以帮助我执行此操作的对象。
The Storageclass seems like a good candidate for the job, but it only allows me to search files within the storage folder, which is outside the public folder.
该Storage级似乎是一个很好的候选人做这份工作，但只允许我存储文件夹，这是外面的公共文件夹中搜索文件。

You could create another disk for Storage class. This would be the best solution for you in my opinion.
您可以为 Storage 类创建另一个磁盘。在我看来，这将是您的最佳解决方案。
In config/filesystems.phpin the disks array add your desired folder. The publicfolder in this case.
在磁盘阵列的config/filesystems.php中，添加所需的文件夹。该市民在这种情况下的文件夹。
'disks' => [
'local' => [
'driver' => 'local',
'root' => storage_path().'/app',
],
'public' => [
'driver' => 'local',
'root' => public_path(),
],
's3' => '....'
Then you can use Storageclass to work within your public folder in the following way:
然后，您可以通过以下方式使用Storage类在您的公用文件夹中工作：
$exists = Storage::disk('public')->exists('file.jpg');
The $exists variable will tell you if file.jpgexists inside the publicfolder because the Storage disk 'public'points to public folder of project.
$exists 变量会告诉你file.jpg 是否存在于public文件夹中，因为存储磁盘“public”指向项目的 public 文件夹。
You can use all the Sessionmethods from documentation, with your custom disk. Just add the disk('public') part.
您可以将文档中的所有会话方法与您的自定义磁盘一起使用。只需添加 disk('public') 部分。
Storage::disk('public')-> // any method you want from
回答by Tarek Adam
Storage::disk('local')->files('optional_dir_name');
Storage::disk('local')->files('optional_dir_name');
or
或者
array_filter(Storage::disk('local')->files(), function ($item) {return strpos($item, 'png');});
array_filter(Storage::disk('local')->files(), function ($item) {return strpos($item, 'png');});
Note that laravel disk has files()and allfiles(). allfilesis recursive.
请注意，laravel 磁盘具有files()和allfiles()。 allfiles是递归的。

Consider using glob. No need to overcomplicate barebones PHP with helper classes/methods in Laravel 5.
考虑使用 glob。无需在 Laravel 5 中使用辅助类/方法使 PHP 过于复杂。
<?php
foreach (glob("/location/for/public/images/*.png") as $filename) {
echo "$filename size " . filesize($filename) . "\n";
}
?>

To list all files in directory use this
要列出目录中的所有文件，请使用此
$dir_path = public_path() . '/dirname';
$dir = new DirectoryIterator($dir_path);
foreach ($dir as $fileinfo) {
if (!$fileinfo->isDot()) {
}
else {
}
}

To list all images in your public dir try this: see here btw http://php.net/manual/en/class.splfileinfo.php
要列出公共目录中的所有图像，请尝试以下操作：请参阅此处 btw http://php.net/manual/en/class.splfileinfo.php
function getImageRelativePathsWfilenames(){
$result = [];
$dirs = File::directories(public_path());
foreach($dirs as $dir){
var_dump($dir); //actually string: /home/mylinuxiser/myproject/public"
$files = File::files($dir);
foreach($files as $f){
var_dump($f); //actually object SplFileInfo
//object(Symfony\Component\Finder\SplFileInfo)#628 (4) {
//["relativePath":"Symfony\Component\Finder\SplFileInfo":private]=>
//string(0) ""
//["relativePathname":"Symfony\Component\Finder\SplFileInfo":private]=>
//string(14) "text1_logo.png"
//["pathName":"SplFileInfo":private]=>
//string(82) "/home/mylinuxiser/myproject/public/img/text1_logo.png"
//["fileName":"SplFileInfo":private]=>
//string(14) "text1_logo.png"
//}
if(ends_with($f, ['.png', '.jpg', '.jpeg', '.gif'])){
$result[] = $f->getRelativePathname(); //prefix your public folder here if you want
}
}
}
return $result; //will be in this case ['img/text1_logo.png']
}

Please use the following code and get all the subdirectories of a particular folder in the public folder. When some click the folder it lists the files inside each folder.
请使用以下代码并获取公共文件夹中特定文件夹的所有子目录。当有人单击文件夹时，它会列出每个文件夹中的文件。
