Deleting all files from a folder using PHP?

phpfiledirectoryglob

提问by getaway

For example I had a folder called `Temp' and I wanted to delete or flush all files from this folder using PHP. Could I do this?

例如,我有一个名为“Temp”的文件夹,我想使用 PHP 从该文件夹中删除或刷新所有文件。我可以这样做吗?

回答by Floern

$files = glob('path/to/temp/*'); // get all file names
foreach($files as $file){ // iterate files
  if(is_file($file))
    unlink($file); // delete file
}

If you want to remove 'hidden' files like .htaccess, you have to use

如果要删除 .htaccess 等“隐藏”文件,则必须使用

$files = glob('path/to/temp/{,.}*', GLOB_BRACE);

If you want to delete everything from folder (including subfolders) use this combination of array_map, unlinkand glob:

如果要删除文件夹(包括子文件夹)中的所有内容,请使用array_map,unlink和 的组合glob

array_map( 'unlink', array_filter((array) glob("path/to/temp/*") ) );

This call can also handle empty directories ( thanks for the tip, @mojuba!)

此调用还可以处理空目录(感谢您的提示,@mojuba!)

Here is a more modern approach using the Standard PHP Library (SPL).

这是使用标准 PHP 库 (SPL)的更现代的方法。

$dir = "path/to/directory";
$di = new RecursiveDirectoryIterator($dir, FilesystemIterator::SKIP_DOTS);
$ri = new RecursiveIteratorIterator($di, RecursiveIteratorIterator::CHILD_FIRST);
foreach ( $ri as $file ) {
    $file->isDir() ?  rmdir($file) : unlink($file);
}
return true;

foreach (new DirectoryIterator('/path/to/directory') as $fileInfo) {
    if(!$fileInfo->isDot()) {
        unlink($fileInfo->getPathname());
    }
}

This code from http://php.net/unlink:

此代码来自http://php.net/unlink

/**
 * Delete a file or recursively delete a directory
 *
 * @param string $str Path to file or directory
 */
function recursiveDelete($str) {
    if (is_file($str)) {
        return @unlink($str);
    }
    elseif (is_dir($str)) {
        $scan = glob(rtrim($str,'/').'/*');
        foreach($scan as $index=>$path) {
            recursiveDelete($path);
        }
        return @rmdir($str);
    }
}

$dir = 'your/directory/';
foreach(glob($dir.'*.*') as $v){
    unlink($v);
}

See readdirand unlink.

请参阅readdirunlink

<?php
    if ($handle = opendir('/path/to/files'))
    {
        echo "Directory handle: $handle\n";
        echo "Files:\n";

        while (false !== ($file = readdir($handle)))
        {
            if( is_file($file) )
            {
                unlink($file);
            }
        }
        closedir($handle);
    }
?>

Assuming you have a folder with A LOT of files reading them all and then deleting in two steps is not that performing. I believe the most performing way to delete files is to just use a system command.

假设你有一个文件夹,里面有很多文件,读取它们,然后分两步删除,效果并不好。我相信删除文件最有效的方法是使用系统命令。

For example on linux I use :

例如在 linux 上我使用:

exec('rm -f '. $absolutePathToFolder .'*');

Or this if you want recursive deletion without the need to write a recursive function

或者如果你想递归删除而不需要编写递归函数

exec('rm -f -r '. $absolutePathToFolder .'*');

the same exact commands exists for any OS supported by PHP. Keep in mind this is a PERFORMING way of deleting files. $absolutePathToFolder MUST be checked and secured before running this code and permissions must be granted.

PHP 支持的任何操作系统都存在相同的命令。请记住,这是一种删除文件的 PERFORMING 方式。在运行此代码之前必须检查并保护 $absolutePathToFolder 并且必须授予权限。

Another solution: This Class delete all files, subdirectories and files in the sub directories.

另一种解决方案:此类删除所有文件、子目录和子目录中的文件。

class Your_Class_Name {
    /**

     * @see http://php.net/manual/de/function.unlink.php
     * @param string $path
     */
    public function delete($path) {
        if (is_dir($path)) {
            array_map(function($value) {
                $this->delete($value);
                rmdir($value);
            },glob($path . '/*', GLOB_ONLYDIR));
            array_map('unlink', glob($path."/*"));
        }
