使用php将目录的全部内容复制到另一个目录

Question

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/");

但它说它找不到流，真正的*.* 没有找到。

其他方式

谢谢 戴夫

Answer 1

适用于一级目录。对于具有多级目录的文件夹，我使用了这个：

function recurseCopy(
    string $sourceDirectory,
    string $destinationDirectory,
    string $childFolder = ''
): void {
    $directory = opendir($sourceDirectory);

    if (is_dir($destinationDirectory) === false) {
        mkdir($destinationDirectory);
    }

    if ($childFolder !== '') {
        if (is_dir("$destinationDirectory/$childFolder") === false) {
            mkdir("$destinationDirectory/$childFolder");
        }

        while (($file = readdir($directory)) !== false) {
            if ($file === '.' || $file === '..') {
                continue;
            }

            if (is_dir("$sourceDirectory/$file") === true) {
                recurseCopy("$sourceDirectory/$file", "$destinationDirectory/$childFolder/$file");
            } else {
                copy("$sourceDirectory/$file", "$destinationDirectory/$childFolder/$file");
            }
        }

        closedir($directory);

        return;
    }

    while (($file = readdir($directory)) !== false) {
        if ($file === '.' || $file === '..') {
            continue;
        }

        if (is_dir("$sourceDirectory/$file") === true) {
            recurseCopy("$sourceDirectory/$file", "$destinationDirectory/$file");
        }
        else {
            copy("$sourceDirectory/$file", "$destinationDirectory/$file");
        }
    }

    closedir($directory);
}

作为described here，这是另一种处理符号链接的方法：

 */
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));
}

Answer 3

copy() 仅适用于文件。

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使用这些命令。例如

`cp -r $src $dest`;

否则，您需要使用opendir/readdir 或scandir 来读取目录的内容，遍历结果，如果 is_dir 对每个结果都返回 true，则递归到它。

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);
        }
    }
}

Answer 4

最好的解决方案是！

<?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
?>

Answer 5

function full_copy( $source, $target ) {
    if ( is_dir( $source ) ) {
        @mkdir( $target );
        $d = dir( $source );
        while ( FALSE !== ( $entry = $d->read() ) ) {
            if ( $entry == '.' || $entry == '..' ) {
                continue;
            }
            $Entry = $source . '/' . $entry; 
            if ( is_dir( $Entry ) ) {
                full_copy( $Entry, $target . '/' . $entry );
                continue;
            }
            copy( $Entry, $target . '/' . $entry );
        }

        $d->close();
    }else {
        copy( $source, $target );
    }
}

Answer 6

使用 Symfony，这很容易实现：

$fileSystem = new Symfony\Component\Filesystem\Filesystem();
$fileSystem->mirror($from, $to);

见https://symfony.com/doc/current/components/filesystem.html

Answer 7

就像在别处所说的那样，copy 仅适用于源文件而不是模式。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

Answer 8

<?php
    function copy_directory( $source, $destination ) {
        if ( is_dir( $source ) ) {
        @mkdir( $destination );
        $directory = dir( $source );
        while ( FALSE !== ( $readdirectory = $directory->read() ) ) {
            if ( $readdirectory == '.' || $readdirectory == '..' ) {
                continue;
            }
            $PathDir = $source . '/' . $readdirectory; 
            if ( is_dir( $PathDir ) ) {
                copy_directory( $PathDir, $destination . '/' . $readdirectory );
                continue;
            }
            copy( $PathDir, $destination . '/' . $readdirectory );
        }

        $directory->close();
        }else {
        copy( $source, $destination );
        }
    }
?>

从最后4行开始，做这个

$source = 'wordpress';//i.e. your source path

和

$destination ='b';

非常感谢 Felix Kling 的出色回答，我非常感激地在我的代码中使用了该回答。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;
}

我的@Kzoty 答案的修剪版本。 谢谢Kzoty。

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();
    }

}

Answer 11

我通过 SPL 目录迭代器克隆整个目录。

function recursiveCopy($source, $destination)
{
    if (!file_exists($destination)) {
        mkdir($destination);
    }

    $splFileInfoArr = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);

    foreach ($splFileInfoArr as $fullPath => $splFileinfo) {
        //skip . ..
        if (in_array($splFileinfo->getBasename(), [".", ".."])) {
            continue;
        }
        //get relative path of source file or folder
        $path = str_replace($source, "", $splFileinfo->getPathname());

        if ($splFileinfo->isDir()) {
            mkdir($destination . "/" . $path);
        } else {
        copy($fullPath, $destination . "/" . $path);
        }
    }
}
#calling the function
recursiveCopy(__DIR__ . "/source", __DIR__ . "/destination");

Answer 12

对于 Linux 服务器，您只需要一行代码即可递归复制，同时保留权限：

exec('cp -a '.$source.' '.$dest);

另一种方法是：

mkdir($dest);
foreach ($iterator = new \RecursiveIteratorIterator(new \RecursiveDirectoryIterator($source, \RecursiveDirectoryIterator::SKIP_DOTS), \RecursiveIteratorIterator::SELF_FIRST) as $item)
{
    if ($item->isDir())
        mkdir($dest.DIRECTORY_SEPARATOR.$iterator->getSubPathName());
    else
        copy($item, $dest.DIRECTORY_SEPARATOR.$iterator->getSubPathName());
}

但速度较慢且不保留权限。

Answer 13

我有类似的情况，我需要在同一台服务器上从一个域复制到另一个域，这正是我的情况，您也可以调整以适合您的情况：

foreach(glob('../folder/*.php') as $file) {
$adjust = substr($file,3);
copy($file, '/home/user/abcde.com/'.$adjust);

注意“substr()”的使用，没有它，目的地变成'/home/user/abcde.com/../folder/'，这可能是你不想要的。因此，我使用 substr() 来消除前 3 个字符 (../) 以获得所需的目的地，即“/home/user/abcde.com/folder/”。因此，您可以调整 substr() 函数以及 glob() 函数，直到它满足您的个人需求。希望这会有所帮助。

基于此处大部分答案的部分内容，带有返回日志记录的冗长注释示例：

它被呈现为一个静态类方法，但也可以作为一个简单的函数工作：

    // is directory ##
    if ( is_dir( $source ) ) {

        $log[] = 'is_dir: '.$source;

        // log results of mkdir call ##
        $log[] = '@mkdir( "'.$destination.'" ): '.@mkdir( $destination );

        // get source directory contents ##
        $source_directory = dir( $source );

        // loop over items in source directory ##
        while ( FALSE !== ( $entry = $source_directory->read() ) ) {

                continue;

            }

            // get full source "entry" path ##
            $source_entry = $source . '/' . $entry; 

            // recurse for directories ##
            if ( is_dir( $source_entry ) ) {

                // return to self, with new arguments ##
                self::copy_recursive( $source_entry, $destination.'/'.$entry, $log );

                // break out of loop, to stop processing ##
                continue;

            }

            $log[] = 'copy: "'.$source_entry.'" --> "'.$destination.'/'.$entry.'"';

            // copy single files ##
            copy( $source_entry, $destination.'/'.$entry );

        }

        // close connection ##
        $source_directory->close();

    } else {

        $log[] = 'copy: "'.$source.'" --> "'.$destination.'"';

        // plain copy, as $destination is a file ##
        copy( $source, $destination );

    }

    // clean up log ##
    $log = array_unique( $log );

    // kick back log for debugging ##
    return $log;

}

调用方式：

// call method ##
$log = \namespace\to\method::copy_recursive( $source, $destination );

// write log to error file - you can also just dump it on the screen ##
error_log( var_export( $log, true ) );

Answer 16

要将整个目录从一个目录复制到另一个目录，首先您应该确定传输文件是否正确传输。为此，我们一一使用复制文件！在正确的目录中。我们复制一个文件并检查它是否为真转到下一个文件并继续...

1- 我用这个函数检查传输每个文件的安全过程：

function checksum($src,$dest)
{
    if(file_exists($src) and file_exists($dest)){
        return md5_file($src) == md5_file($dest) ? true : false;
    }else{
        return false;
    }
}

2- 现在我将文件从 src 一个一个复制到 dest，检查它然后继续。 （对于我不想复制的文件夹，请使用排除数组）

$src  = __DIR__ . '/src';
$dest = __DIR__ . '/dest';
$exclude = ['.', '..'];

function copyDir($src, $dest, $exclude)
{

    !is_dir($dest) ? mkdir($dest) : '';

    foreach (scandir($src) as $item) {

        $srcPath = $src . '/' . $item;
        $destPath = $dest . '/' . $item;

        if (!in_array($item, $exclude)) {

            if (is_dir($srcPath)) {

                copyDir($srcPath, $destPath, $exclude);

            } else {

                copy($srcPath, $destPath);

                if (checksum($srcPath, $destPath)) {
                    echo 'Success transfer for:' . $srcPath . '<br>';
                }else{
                    echo 'Failed transfer for:' . $srcPath . '<br>';
                }
            }
        }
    }

}
