php在線解壓zip_PHP怎麼解壓ZIP文件

Ⅰ （急）php 解壓文件（unzip）

1、先下載 http://www.canphp.com/upload/canphp1.4.zip
2、裡面有個 canphp\lib\Zip.class.php 文件，僅僅需要這個文件就行了，這是個壓縮與解壓縮的類，在需要的地方，包含這個文件即可使用。
3、使用方法：
（1）壓縮：
$zip=new Zip();
$zip->compress('template.zip','template');//將template目錄的所有文件壓縮到template.zip文件
（2）解壓：
$zip=new Zip();
$zip->decompress('template.zip','template2');//將template.zip壓縮文件，解壓到template2目錄。
4、兩種方法的返回值請參考Zip.class.php 或 var_mp 返回值
5、實際測試成功，只是返回一些notice。我的代碼如下：
<?php
require_once "zip.class.php";
$zip = new Zip();
$zip->compress('xtw.zip', 'template');
$zip->decompress('xtw.zip', 'template2');
?>

Ⅱ 怎樣用php壓縮解壓rar,zip文件

要用PHP壓縮解壓文件，常用的方法是調用命令行去執行解壓縮操作
可以用exec()
、system()等函數調用shell命令
Linux下解壓縮命令是tar
[-cxtzjvfpPN]
文件與目錄，tar命令可以壓縮解壓.tar、.gz、.tar.gz、.tgz、.bz2、.tar.bz2、.Z、.tar.Z、.zip這些類型的文件
Linux下默認無法使用rar格式的，要另外安裝RAR
for
Linux，然後使用rar和unrar命令解壓縮rar格式的壓縮文件

Ⅲ PHP怎麼解壓ZIP文件

?php

$zip=zip_open("/tmp/test2.zip");

if($zip){

while($zip_entry=zip_read($zip)){
echo"Name:".zip_entry_name($zip_entry)."
";
echo"ActualFilesize:".zip_entry_filesize($zip_entry)."
";
echo"CompressedSize:".zip_entry_compressedsize($zip_entry)."
";
echo"CompressionMethod:".zip_entry_compressionmethod($zip_entry)."
";

if(zip_entry_open($zip,$zip_entry,"r")){
echo"FileContents:
";
$buf=zip_entry_read($zip_entry,zip_entry_filesize($zip_entry));
echo"$buf
";

zip_entry_close($zip_entry);
}
echo"
";

}

zip_close($zip);

}

?>

Ⅳ PHP下載zip文件到本地並解壓

下載用socket，或者開了allow_url_fopen 直接用file
解壓zip用自帶的zip庫即可

之前寫過的一個php的離線下載 http://www.ifuns.cn/_test/download.html
zip解壓看手冊，就那幾個函數

Ⅳ 怎麼用php寫一個表單上傳zip格式的壓縮包並解壓到根目錄的指定目錄中

<?php
if($_FILES["file"]["error"]>0){
echo"<script>console.log('ReturnCode:".$_FILES["file"]["error"]."');</script>";
}
else{
if(!file_exists("upload/".$_FILES["file"]["name"])){
move_uploaded_file($_FILES["file"]["tmp_name"],
"upload/".$_FILES["file"]["name"]);
echo"Storedin:"."upload/".$_FILES["file"]["name"];
system('zip解壓縮命令');
}
else{
system('zip解壓縮命令');
}
}
?>

因為php即使拓展了zip庫，也不能夠實現解壓縮，而且拓展zip庫會要更改php.ini，所以推介下載7z的命令行版本，用系統命令解決。╮(￣▽￣"")╭

Ⅵ 請高手指點：PHP 如何解壓縮zip格式壓縮的文件或壓縮文件夾內的文件到指定目錄

/**
* PHP在線壓縮/解壓實例
*/

date_default_timezone_set('prc');

$zip = new engine_compress_decompress();

if (isset($_POST))
{
$sourcePath = ''; //默認位置

if (isset($_FILES['upfile'])) //上傳文件
{
$stmp = $zip->fileUpload('upfile');
$sourcePath = $stmp['sourcefile'];
$upfileError = $stmp['error'];
}
elseif (isset($_POST['inputfile'])) //輸入目錄或者文件
{
$sourcePath = $_POST['inputfile'];
}
elseif (isset($_POST['decompresssourcefiles'])) //解壓縮提交
{
$isDecompress = $zip->decompress($_POST['decompresssourcefiles'], $_POST['topath']);
if (!empty($isDecompress['filelist']))
{
$href = '<script type="text/javascript" language="javascript">window.location.href=\'#decompress\'</script>';
}

}

$fileList = $zip->fileArray($sourcePath); //解壓縮文件列表

if (isset($_POST['compressinputfileorfolder'])) //壓縮文件目錄或者文件輸入
{
$sourcePath = $_POST['compressinputfileorfolder'];
$href = '<script type="text/javascript" language="javascript">window.location.href=\'#compress\'</script>';
$compressFilelist = $zip->compressFileArray($sourcePath); //壓縮文件列表
}
elseif ((isset($_POST['selectcompressfilelist'])) && (isset($_POST['compresssavefilename'])))
{
$compressFiles = $zip->compress($_POST['selectcompressfilelist'], $_POST['compresssavefilename']); //真實檢測
$isCompress = $zip->CompileZipFile($compressFiles, $zip->savePath, 'all');
if (!empty($isCompress))
{
$href = '<script type="text/javascript" language="javascript">window.location.href=\'#compress\'</script>';
}
}
}

Ⅶ 要一個php腳本，能夠解壓php空間里的zip文件。

呵呵簡單啊孝納一個文件就可巧歷沒以了。。。
自己記得修改密碼。默認是123456 你可以自己找找裡面有沒有外連，
搜索http 保證安全。

-------------------------------------------------------------------

<?php

//驗證密碼
$password = "123456";

?>

把中間的代碼復制下來，然後用記事本另存為 jieya.php ,
上傳到和zip一個目錄下，打開這個地址，選擇一下，目錄記得也要寫，
寫上密碼就按解壓就可以了，十分方便簡單，
