Copy entire contents of a directory to another using php
提问by dave
I tried to copy the entire contents of the directory to another location using
我尝试使用将目录的全部内容复制到另一个位置
copy ("old_location/*.*","new_location/");
but it says it cannot find stream, true *.*is not found.
但它说它找不到流，没有找到真*.*。
Any other way
任何其他方式
Thanks Dave

It seems that copy onlyhandle single files. Here is a function for copying recursively I found in this noteon the copy documentation page:
似乎 copy只处理单个文件。这是我在复制文档页面上的注释中找到的递归复制函数：
<?php
function recurse_copy($src,$dst) {
$dir = opendir($src);
@mkdir($dst);
while(false !== ( $file = readdir($dir)) ) {
if (( $file != '.' ) && ( $file != '..' )) {
if ( is_dir($src . '/' . $file) ) {
recurse_copy($src . '/' . $file,$dst . '/' . $file);
}
else {
copy($src . '/' . $file,$dst . '/' . $file);
}
}
}
closedir($dir);
}
?>

As described here, this is another approach that takes care of symlinks too:
如此处所述，这是另一种处理符号链接的方法：
/**
* Copy a file, or recursively copy a folder and its contents
* @author Aidan Lister <[email protected]>
* @version 1.0.1
* @link http://aidanlister.com/2004/04/recursively-copying-directories-in-php/
* @param string $source Source path
* @param string $dest Destination path
* @param int $permissions New folder creation permissions
* @return bool Returns true on success, false on failure
*/
function xcopy($source, $dest, $permissions = 0755)
{
$sourceHash = hashDirectory($source);
// Check for symlinks
if (is_link($source)) {
return symlink(readlink($source), $dest);
}
// Simple copy for a file
if (is_file($source)) {
return copy($source, $dest);
}
// Make destination directory
if (!is_dir($dest)) {
mkdir($dest, $permissions);
}
// Loop through the folder
$dir = dir($source);
while (false !== $entry = $dir->read()) {
// Skip pointers
if ($entry == '.' || $entry == '..') {
continue;
}
// Deep copy directories
if($sourceHash != hashDirectory($source."/".$entry)){
xcopy("$source/$entry", "$dest/$entry", $permissions);
}
}
// Clean up
$dir->close();
return true;
}
// In case of coping a directory inside itself, there is a need to hash check the directory otherwise and infinite loop of coping is generated
function hashDirectory($directory){
if (! is_dir($directory)){ return false; }
$files = array();
$dir = dir($directory);
while (false !== ($file = $dir->read())){
if ($file != '.' and $file != '..') {
if (is_dir($directory . '/' . $file)) { $files[] = hashDirectory($directory . '/' . $file); }
else { $files[] = md5_file($directory . '/' . $file); }
}
}
$dir->close();
return md5(implode('', $files));
}

copy() only works with files.
copy() 仅适用于文件。
Both the DOS copy and Unix cp commands will copy recursively - so the quickest solution is just to shell out and use these. e.g.
DOS 复制和 Unix cp 命令都将递归复制 - 所以最快的解决方案就是外壳并使用它们。例如
`cp -r $src $dest`;
Otherwise you'll need to use the opendir/readdiror scandirto read the contents of the directory, iterate through the results and if is_dir returns true for each one, recurse into it.
否则，您将需要使用opendir/readdir或scandir读取目录的内容，遍历结果，如果 is_dir 为每个结果返回 true，则递归到它。
e.g.
例如
function xcopy($src, $dest) {
foreach (scandir($src) as $file) {
if (!is_readable($src . '/' . $file)) continue;
if (is_dir($src .'/' . $file) && ($file != '.') && ($file != '..') ) {
mkdir($dest . '/' . $file);
xcopy($src . '/' . $file, $dest . '/' . $file);
} else {
copy($src . '/' . $file, $dest . '/' . $file);
}
}
}

The best solution is!
最好的解决办法是！
<?php
$src = "/home/www/domain-name.com/source/folders/123456";
$dest = "/home/www/domain-name.com/test/123456";
shell_exec("cp -r $src $dest");
echo "<H3>Copy Paste completed!</H3>"; //output when done

Like said elsewhere, copyonly works with a single file for source and not a pattern. If you want to copy by pattern, use globto determine the files, then run copy. This will not copy subdirectories though, nor will it create the destination directory.
就像别处说的那样，copy只适用于源文件而不是模式的单个文件。如果要按模式复制，请使用glob确定文件，然后运行复制。但这不会复制子目录，也不会创建目标目录。
function copyToDir($pattern, $dir)
{
foreach (glob($pattern) as $file) {
if(!is_dir($file) && is_readable($file)) {
$dest = realpath($dir . DIRECTORY_SEPARATOR) . basename($file);
copy($file, $dest);
}
}
}
copyToDir('./test/foo/*.txt', './test/bar'); // copies all txt files

from the last 4th line , make this
从最后第四行开始，做这个
$source = 'wordpress';//i.e. your source path
and
和
$destination ='b';

Full thanks must go to Felix Kling for his excellent answer which I have gratefully used in my code. I offer a small enhancement of a boolean return value to report success or failure:
必须非常感谢 Felix Kling 的出色回答，我非常感谢在我的代码中使用了这些回答。我提供了一个布尔返回值的小增强来报告成功或失败：
function recurse_copy($src, $dst) {
$dir = opendir($src);
$result = ($dir === false ? false : true);
if ($result !== false) {
$result = @mkdir($dst);
if ($result === true) {
while(false !== ( $file = readdir($dir)) ) {
if (( $file != '.' ) && ( $file != '..' ) && $result) {
if ( is_dir($src . '/' . $file) ) {
$result = recurse_copy($src . '/' . $file,$dst . '/' . $file);
} else {
$result = copy($src . '/' . $file,$dst . '/' . $file);
}
}
}
closedir($dir);
}
}
return $result;
}

With Symfony this is very easy to accomplish:
使用 Symfony，这很容易实现：
$fileSystem = new Symfony\Component\Filesystem\Filesystem();
$fileSystem->mirror($from, $to);
See https://symfony.com/doc/current/components/filesystem.html

My pruned version of @Kzoty answer. Thank you Kzoty.

Usage
用法
Helper::copy($sourcePath, $targetPath);
class Helper {
static function copy($source, $target) {
if (!is_dir($source)) {//it is a file, do a normal copy
copy($source, $target);
return;
}
//it is a folder, copy its files & sub-folders
@mkdir($target);
$d = dir($source);
$navFolders = array('.', '..');
while (false !== ($fileEntry=$d->read() )) {//copy one by one
//skip if it is navigation folder . or ..
if (in_array($fileEntry, $navFolders) ) {
continue;
}
//do copy
$s = "$source/$fileEntry";
$t = "$target/$fileEntry";
self::copy($s, $t);
}
$d->close();
}
}
