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！

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@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' >

$zip = new ZipArchive;
$res = $zip->open(__DIR__ . '/' .$zip_filename);

简单的PHP解压缩函数。请确保您的服务器上安装了zip扩展。
/**
* Unzip
* @param string $zip_file_path Eg - /tmp/my.zip
* @param string $extract_path Eg - /tmp/new_dir_name
* @return boolean
*/
function unzip(string $zip_file_path, string $extract_dir_path) {
$zip = new \ZipArchive;
$res = $zip->open($zip_file_path);
if ($res === TRUE) {
$zip->extractTo($extract_dir_path);
$zip->close();
return TRUE;
} else {
return FALSE;
}
}
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”);
使用下面的PHP代码，文件名在URL参数“name”中
<?php
$fileName = $_GET['name'];
if (isset($fileName)) {
$zip = new ZipArchive;
$res = $zip->open($fileName);
if ($res === TRUE) {
$zip->extractTo('./');
$zip->close();
echo 'Extracted file "'.$fileName.'"';
} else {
echo 'Cannot find the file name "'.$fileName.'" (the file name should include extension (.zip, ...))';
}
}
else {
echo 'Please set file name in the "name" param';
}
?>
