如何通过php实现zip文件解压操作
rar文件解压php没有直接支持的，不过可以通过下载将非线程安全的dll然后扔到php的ext目录下，之后按照下面的步骤操作即可。
打开php.ini.
加一行 extension=php_rar.dll
重启web服务器 和php
复制代码
代码如下:
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如何解压?求简短一点的代码。
?php
//验证密码
$password = "123";

如何用php解压缩文件
您好，ZIP格式的可以
?php
//需开启配置 php_zip.dll
//phpinfo();
header("Content-type:text/html;charset=gb2312");
function get_zip_originalsize($filename, $path) {
//先判断待解压的文件是否存在
if(!file_exists($filename)){
die("文件 $filename 不存在！");
}
$starttime = explode(' ',microtime()); //解压开始的时间
//将文件名和路径转成windows系统默认的gb2312编码，否则将会读取不到
$filename = iconv("utf-8","gb2312",$filename);
$path = iconv("utf-8","gb2312",$path);
//打开压缩包
$resource = zip_open($filename);
$i = 1;
//遍历读取压缩包里面的一个个文件
while ($dir_resource = zip_read($resource)) {
//如果能打开则继续
if (zip_entry_open($resource,$dir_resource)) {
//获取当前项目的名称,即压缩包里面当前对应的文件名
$file_name = $path.zip_entry_name($dir_resource);
//以最后一个“/”分割,再用字符串截取出路径部分
$file_path = substr($file_name,0,strrpos($file_name, "/"));
//如果路径不存在，则创建一个目录，true表示可以创建多级目录
if(!is_dir($file_path)){
mkdir($file_path,0777,true);
}
//如果不是目录，则写入文件
if(!is_dir($file_name)){
//读取这个文件
$file_size = zip_entry_filesize($dir_resource);
//最大读取6M，如果文件过大，跳过解压，继续下一个
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++." 此文件已被跳过，原因：文件过大， - ".iconv("gb2312","utf-8",$file_name)." /p";
}
}
//关闭当前
zip_entry_close($dir_resource);
}
}
//关闭压缩包
zip_close($resource);
$endtime = explode(' ',microtime()); //解压结束的时间
$thistime = $endtime[0]+$endtime[1]-($starttime[0]+$starttime[1]);
$thistime = round($thistime,3); //保留3为小数
echo "p解压完毕！，本次解压花费：$thistime 秒。/p";
}
$size = get_zip_originalsize('temp/test.zip','temp/');

大侠们，请问php在线解压rar文档 代码，急需要...........谢谢！
PHP没有处理rar压缩的函数，自己编写也不太现实，我建议在php里面调用rar.exe来压缩和解压缩文件，调用rar.exe的时候参数比较多，可以运行rar.exe /?显示，一般参数格式是：
用法: rar 命令 -开关 1 -开关 N 压缩文件 文件...
@列表文件... 解压路径\
命令
a 添加文件到压缩文件
c 添加压缩文件注释
cf 添加文件注释
ch 改变压缩文件参数
cw 写入压缩文件注释到文件
d 删除压缩文件中的文件
e 解压压缩文件到当前目录
例如要解压当前文件夹下的a.rar的php语句是：
system('"C:\Program Files (x86)\WinRAR\rar.exe" e .\a.rar');
如果你不是WIN7，或者安装文件夹不同，注意更改文件位置。
