如何在PHP中[递归]压缩目录?
目录类似于:如何在PHP中[递归]压缩目录?,php,directory,zip,directory-structure,recursion,Php,Directory,Zip,Directory Structure,Recursion,目录类似于: home/ file1.html file2.html Another_Dir/ file8.html Sub_Dir/ file19.html 我使用的是PHPMyAdmin中使用的同一个PHP Zip类。我不知道如何压缩一个目录而不仅仅是一个文件。以下是我目前掌握的情况: $aFiles = $this->da->getDirTree($target); /* $aFiles is something like, p
home/
file1.html
file2.html
Another_Dir/
file8.html
Sub_Dir/
file19.html
我使用的是PHPMyAdmin中使用的同一个PHP Zip类。我不知道如何压缩一个目录而不仅仅是一个文件。以下是我目前掌握的情况:
$aFiles = $this->da->getDirTree($target);
/* $aFiles is something like, path => filetime
Array
(
[home] =>
[home/file1.html] => 1251280379
[home/file2.html] => 1251280377
etc...
)
*/
$zip = & new Zip();
foreach( $aFiles as $fileLocation => $time ){
$file = $target . "/" . $fileLocation;
if ( is_file($file) ){
$buffer = file_get_contents($file);
$zip->addFile($buffer, $fileLocation);
}
}
THEN_SOME_PHP_CLASS::toDownloadData($zip); // this bit works ok
但当我尝试解压缩相应的下载zip文件时,我得到“不允许操作”
只有当我尝试在mac上解压时,当我通过命令行解压文件unzips ok时,才会发生此错误。我是否需要在下载时发送特定的内容类型,当前为“application/zip”尝试这里有一个简单的函数,可以递归压缩任何文件或目录,只需要加载zip扩展名
function Zip($source, $destination)
{
if (!extension_loaded('zip') || !file_exists($source)) {
return false;
}
$zip = new ZipArchive();
if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
return false;
}
$source = str_replace('\\', '/', realpath($source));
if (is_dir($source) === true)
{
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);
foreach ($files as $file)
{
$file = str_replace('\\', '/', $file);
// Ignore "." and ".." folders
if( in_array(substr($file, strrpos($file, '/')+1), array('.', '..')) )
continue;
$file = realpath($file);
if (is_dir($file) === true)
{
$zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
}
else if (is_file($file) === true)
{
$zip->addFromString(str_replace($source . '/', '', $file), file_get_contents($file));
}
}
}
else if (is_file($source) === true)
{
$zip->addFromString(basename($source), file_get_contents($source));
}
return $zip->close();
}
可以这样称呼:
Zip('/folder/to/compress/', './compressed.zip');
我将的答案编辑为第三个参数,当将第三个参数设置为true
时,所有文件都将添加到主目录下,而不是直接添加到zip文件夹中
如果zip文件存在,该文件也将被删除
例如:
Zip('/path/to/maindirectory','/path/to/compressed.zip',true);
第三个参数true
zip结构:
maindirectory
--- file 1
--- file 2
--- subdirectory 1
------ file 3
------ file 4
--- subdirectory 2
------ file 5
------ file 6
file 1
file 2
subdirectory 1
--- file 3
--- file 4
subdirectory 2
--- file 5
--- file 6
第三个参数false
或缺少zip结构:
maindirectory
--- file 1
--- file 2
--- subdirectory 1
------ file 3
------ file 4
--- subdirectory 2
------ file 5
------ file 6
file 1
file 2
subdirectory 1
--- file 3
--- file 4
subdirectory 2
--- file 5
--- file 6
编辑代码:
function Zip($source, $destination, $include_dir = false)
{
if (!extension_loaded('zip') || !file_exists($source)) {
return false;
}
if (file_exists($destination)) {
unlink ($destination);
}
$zip = new ZipArchive();
if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
return false;
}
$source = str_replace('\\', '/', realpath($source));
if (is_dir($source) === true)
{
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);
if ($include_dir) {
$arr = explode("/",$source);
$maindir = $arr[count($arr)- 1];
$source = "";
for ($i=0; $i < count($arr) - 1; $i++) {
$source .= '/' . $arr[$i];
}
$source = substr($source, 1);
$zip->addEmptyDir($maindir);
}
foreach ($files as $file)
{
$file = str_replace('\\', '/', $file);
// Ignore "." and ".." folders
if( in_array(substr($file, strrpos($file, '/')+1), array('.', '..')) )
continue;
$file = realpath($file);
if (is_dir($file) === true)
{

}

}
}
}
else if (is_file($source) === true)
{
$zip->addFromString(basename($source), file_get_contents($source));
}
return $zip->close();
}
函数Zip($source,$destination,$include\u dir=false)
{
如果(!extension_loaded('zip')| |!文件_存在($source)){
返回false;
}
如果(文件_存在($destination)){
取消链接(目的地);

}

如果($include_dir){

对于($i=0;$iaddEmptyDir($maindir);
}
foreach($files作为$file)
{
$file=str\u replace(“\\\”、“/”、$file);
//忽略“.”和“.”文件夹
if(在数组(substr($file,strrpos($file,“/”)+1)中,数组(“.”,“…”))
继续;

返回$zip->close();
}
我需要在Mac OSX中运行此Zip函数
所以我总是把那家讨厌的小店拉上拉链
我通过加入额外的忽略文件进行了改编
function zipIt($source, $destination, $include_dir = false, $additionalIgnoreFiles = array())
{
// Ignore "." and ".." folders by default
$defaultIgnoreFiles = array('.', '..');
// include more files to ignore
$ignoreFiles = array_merge($defaultIgnoreFiles, $additionalIgnoreFiles);
if (!extension_loaded('zip') || !file_exists($source)) {
return false;
}
if (file_exists($destination)) {
unlink ($destination);
}
$zip = new ZipArchive();
if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
return false;
}
$source = str_replace('\\', '/', realpath($source));
if (is_dir($source) === true)
{
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);
if ($include_dir) {
$arr = explode("/",$source);
$maindir = $arr[count($arr)- 1];
$source = "";
for ($i=0; $i < count($arr) - 1; $i++) {
$source .= '/' . $arr[$i];
}
$source = substr($source, 1);
$zip->addEmptyDir($maindir);
}
foreach ($files as $file)
{
$file = str_replace('\\', '/', $file);
// purposely ignore files that are irrelevant
if( in_array(substr($file, strrpos($file, '/')+1), $ignoreFiles) )
continue;
$file = realpath($file);
if (is_dir($file) === true)
{
$zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
}
else if (is_file($file) === true)
{
$zip->addFromString(str_replace($source . '/', '', $file), file_get_contents($file));
}
}
}
else if (is_file($source) === true)
{
$zip->addFromString(basename($source), file_get_contents($source));
}
return $zip->close();
}
函数zipIt($source,$destination,$include_dir=false,$additionalIgnoreFiles=array())
{
//默认情况下忽略“.”和“.”文件夹
$defaultIgnoreFiles=数组('.','..);
//包括更多要忽略的文件
$ignoreFiles=数组\合并($defaultIgnoreFiles,$additionalIgnoreFiles);
如果(!extension_loaded('zip')| |!文件_存在($source)){
返回false;
}
如果(文件_存在($destination)){
取消链接(目的地);
}
$zip=新的ZipArchive();

对于($i=0;$izipIt('/path/to/folder','/path/to/compressed.zip',false,数组('.DS_Store') 另一个递归目录树归档,作为ZipArchive的扩展实现。另外,还包括一个单语句树压缩辅助函数。与其他ZipArchive函数一样,支持可选的localname。要添加的错误处理代码
class ExtendedZip extends ZipArchive {
// Member function to add a whole file system subtree to the archive
public function addTree($dirname, $localname = '') {
if ($localname)
$this->addEmptyDir($localname);
$this->_addTree($dirname, $localname);
}
// Internal function, to recurse
protected function _addTree($dirname, $localname) {
$dir = opendir($dirname);
while ($filename = readdir($dir)) {
// Discard . and ..
if ($filename == '.' || $filename == '..')
continue;
// Proceed according to type
$path = $dirname . '/' . $filename;
$localpath = $localname ? ($localname . '/' . $filename) : $filename;
if (is_dir($path)) {
// Directory: add & recurse
$this->addEmptyDir($localpath);
$this->_addTree($path, $localpath);
}
else if (is_file($path)) {
// File: just add
$this->addFile($path, $localpath);
}
}
closedir($dir);
}
// Helper function
public static function zipTree($dirname, $zipFilename, $flags = 0, $localname = '') {
$zip = new self();
$zip->open($zipFilename, $flags);
$zip->addTree($dirname, $localname);
$zip->close();
}
}
// Example
ExtendedZip::zipTree('/foo/bar', '/tmp/archive.zip', ZipArchive::CREATE);
用法:thisfile.php?dir=./path/to/folder(压缩后,它也开始下载)
