我想知道,删除一个包含所有文件的目录最简单的方法是什么?
我使用的是rmdir(PATH。“/”。美元价值);要删除一个文件夹,但是,如果里面有文件,我根本不能删除它。

这是一个更短的版本,对我来说很好
function deleteDirectory($dirPath) {
if (is_dir($dirPath)) {
$objects = scandir($dirPath);
foreach ($objects as $object) {
if ($object != "." && $object !="..") {
if (filetype($dirPath . DIRECTORY_SEPARATOR . $object) == "dir") {
deleteDirectory($dirPath . DIRECTORY_SEPARATOR . $object);
} else {
unlink($dirPath . DIRECTORY_SEPARATOR . $object);
}
}
}
reset($objects);
rmdir($dirPath);
}
}
其他回答
现在至少有两种选择。
Before deleting the folder, delete all its files and folders (and this means recursion!). Here is an example: public static function deleteDir($dirPath) { if (! is_dir($dirPath)) { throw new InvalidArgumentException("$dirPath must be a directory"); } if (substr($dirPath, strlen($dirPath) - 1, 1) != '/') { $dirPath .= '/'; } $files = glob($dirPath . '*', GLOB_MARK); foreach ($files as $file) { if (is_dir($file)) { self::deleteDir($file); } else { unlink($file); } } rmdir($dirPath); } And if you are using 5.2+ you can use a RecursiveIterator to do it without implementing the recursion yourself: $dir = 'samples' . DIRECTORY_SEPARATOR . 'sampledirtree'; $it = new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS); $files = new RecursiveIteratorIterator($it, RecursiveIteratorIterator::CHILD_FIRST); foreach($files as $file) { if ($file->isDir()){ rmdir($file->getRealPath()); } else { unlink($file->getRealPath()); } } rmdir($dir);
在上面的答案上加上2美分,顺便说一句,这很棒
在glob(或类似)函数扫描/读取目录后,添加一个条件来检查响应是否为空,否则将抛出为foreach()警告提供的无效参数。所以…
if( ! empty( $files ) )
{
foreach( $files as $file )
{
// do your stuff here...
}
}
我的完整函数(作为对象方法):
private function recursiveRemoveDirectory( $directory )
{
if( ! is_dir( $directory ) )
{
throw new InvalidArgumentException( "$directory must be a directory" );
}
if( substr( $directory, strlen( $directory ) - 1, 1 ) != '/' )
{
$directory .= '/';
}
$files = glob( $directory . "*" );
if( ! empty( $files ) )
{
foreach( $files as $file )
{
if( is_dir( $file ) )
{
$this->recursiveRemoveDirectory( $file );
}
else
{
unlink( $file );
}
}
}
rmdir( $directory );
} // END recursiveRemoveDirectory()
使用DirectoryIterator等价于之前的答案…
function deleteFolder($rootPath)
{
foreach(new DirectoryIterator($rootPath) as $fileToDelete)
{
if($fileToDelete->isDot()) continue;
if ($fileToDelete->isFile())
unlink($fileToDelete->getPathName());
if ($fileToDelete->isDir())
deleteFolder($fileToDelete->getPathName());
}
rmdir($rootPath);
}
像这样的东西?
function delete_folder($folder) {
$glob = glob($folder);
foreach ($glob as $g) {
if (!is_dir($g)) {
unlink($g);
} else {
delete_folder("$g/*");
rmdir($g);
}
}
}
类似Playnox的解决方案,但有优雅的内置DirectoryIterator:
function delete_directory($dirPath){
if(is_dir($dirPath)){
$objects=new DirectoryIterator($dirPath);
foreach ($objects as $object){
if(!$object->isDot()){
if($object->isDir()){
delete_directory($object->getPathname());
}else{
unlink($object->getPathname());
}
}
}
rmdir($dirPath);
}else{
throw new Exception(__FUNCTION__.'(dirPath): dirPath is not a directory!');
}
}
