用php解压缩文件

我想解压缩一个文件，这工作得很好

system('unzip File.zip');

但我需要通过URL传递文件名，不能让它工作，这就是我所拥有的。

$master = $_GET["master"];
system('unzip $master.zip');

我错过了什么?我知道一定是我忽视的小而愚蠢的事情。

谢谢你！

简单地尝试这个yourDestinationDir是目的地提取到或删除-d yourDestinationDir提取到根目录。

$master = 'someDir/zipFileName';
$data = system('unzip -d yourDestinationDir '.$master.'.zip');

只改变

system('unzip $master.zip');

到这个

system('unzip ' . $master . '.zip');

或者这个

系统(“{$大师}. zip解压缩”);

可以使用预包装函数

function unzip_file($file, $destination){
    // create object
    $zip = new ZipArchive() ;
    // open archive
    if ($zip->open($file) !== TRUE) {
        return false;
    }
    // extract contents to destination directory
    $zip->extractTo($destination);
    // close archive
    $zip->close();
        return true;
}

如何使用它。

if(unzip_file($file["name"],'uploads/')){
echo 'zip archive extracted successfully';
}else{
  echo 'zip archive extraction failed';
}

我更新了Morteza Ziaeemehr的答案，以一个更干净和更好的代码，这将解压一个文件提供的形式到当前目录使用DIR。

我更新了@rdlowrey的答案，以一个更干净和更好的代码，这将解压文件到当前目录使用__DIR__。

<?php 
    // config
    // -------------------------------
    // only file name + .zip
    $zip_filename = "YOURFILENAME.zip";
?>

<!DOCTYPE html>
<html>
<head>
    <meta charset='utf-8' >
    <title>Unzip</title>
    <style>
        body{
            font-family: arial, sans-serif;
            word-wrap: break-word;
        }
        .wrapper{
            padding:20px;
            line-height: 1.5;
            font-size: 1rem;
        }
        span{
            font-family: 'Consolas', 'courier new', monospace;

        $zip = new ZipArchive;

使用getcwd()在同一目录中进行解压缩

<?php
$unzip = new ZipArchive;
$out = $unzip->open('wordpress.zip');
if ($out === TRUE) {
  $unzip->extractTo(getcwd());
  $unzip->close();
  echo 'File unzipped';
} else {
  echo 'Error';
}
?>
