如何通過php實現zip文件解壓操作
rar文件解壓php沒有直接支持的，不過可以通過下載將非線程安全的dll然後扔到php的ext目錄下，之後按照下面的步驟操作即可。
打開php.ini.
加一行 extension=php_rar.dll
重啟web伺服器 和php
複製代碼
代碼如下:
public function _unzip($fileName,$extractTO){
$fileName = iconv(‘utf-8′,’gb2312’,”upload/zip/8月.rar”);
// echo $fileName . ‘/br’;
$extractTo = “upload/zip/TEST/”;
$rar_file = rar_open($fileName) or die(‘could not open rar’);
$list = rar_list($rar_file) or die(‘could not get list’);
// print_r($list);
foreach($list as $file) {
$pattern = ‘/\”.*\”/’;
preg_match($pattern, $file, $matches, PREG_OFFSET_CAPTURE);
$pathStr=$matches[0][0];
$pathStr=str_replace(“\””,”,$pathStr);
// print_r($pathStr);
$entry = rar_entry_get($rar_file, $pathStr) or die(‘/brentry not found’);
$entry-extract($extractTo); // extract to the current dir
}
rar_close($rar_file);
}
php如何解壓?求簡短一點的代碼。
?php
//驗證密碼
$password = “123”;

如何用php解壓縮文件
您好，ZIP格式的可以
?php
//需開啟配置 php_zip.dll
//phpinfo();
header(“Content-type:text/html;charset=gb2312”);
function get_zip_originalsize($filename, $path) {
//先判斷待解壓的文件是否存在
if(!file_exists($filename)){
die(“文件 $filename 不存在！”);
}
$starttime = explode(‘ ‘,microtime()); //解壓開始的時間
//將文件名和路徑轉成windows系統默認的gb2312編碼，否則將會讀取不到
$filename = iconv(“utf-8″,”gb2312”,$filename);
$path = iconv(“utf-8″,”gb2312”,$path);
//打開壓縮包
$resource = zip_open($filename);
$i = 1;
//遍歷讀取壓縮包裡面的一個個文件
while ($dir_resource = zip_read($resource)) {
//如果能打開則繼續
if (zip_entry_open($resource,$dir_resource)) {
//獲取當前項目的名稱,即壓縮包裡面當前對應的文件名
$file_name = $path.zip_entry_name($dir_resource);
//以最後一個「/」分割,再用字元串截取出路徑部分
$file_path = substr($file_name,0,strrpos($file_name, “/”));
//如果路徑不存在，則創建一個目錄，true表示可以創建多級目錄
if(!is_dir($file_path)){
mkdir($file_path,0777,true);
}
//如果不是目錄，則寫入文件
if(!is_dir($file_name)){
//讀取這個文件
$file_size = zip_entry_filesize($dir_resource);
//最大讀取6M，如果文件過大，跳過解壓，繼續下一個
if($file_size(1024*1024*6)){
$file_content = zip_entry_read($dir_resource,$file_size);
file_put_contents($file_name,$file_content);
}else{
echo “p “.$i++.” 此文件已被跳過，原因：文件過大， – “.iconv(“gb2312″,”utf-8″,$file_name).” /p”;
}
}
//關閉當前
zip_entry_close($dir_resource);
}
}
//關閉壓縮包
zip_close($resource);
$endtime = explode(‘ ‘,microtime()); //解壓結束的時間
$thistime = $endtime[0]+$endtime[1]-($starttime[0]+$starttime[1]);
$thistime = round($thistime,3); //保留3為小數
echo “p解壓完畢！，本次解壓花費：$thistime 秒。/p”;
}
$size = get_zip_originalsize(‘temp/test.zip’,’temp/’);

大俠們，請問php在線解壓rar文檔 代碼，急需要………..謝謝！
PHP沒有處理rar壓縮的函數，自己編寫也不太現實，我建議在php裡面調用rar.exe來壓縮和解壓縮文件，調用rar.exe的時候參數比較多，可以運行rar.exe /?顯示，一般參數格式是：
用法: rar 命令 -開關 1 -開關 N 壓縮文件 文件…
@列表文件… 解壓路徑\
命令
a 添加文件到壓縮文件
c 添加壓縮文件注釋
cf 添加文件注釋
ch 改變壓縮文件參數
cw 寫入壓縮文件注釋到文件
d 刪除壓縮文件中的文件
e 解壓壓縮文件到當前目錄
例如要解壓當前文件夾下的a.rar的php語句是：
system(‘”C:\Program Files (x86)\WinRAR\rar.exe” e .\a.rar’);
如果你不是WIN7，或者安裝文件夾不同，注意更改文件位置。
