我正在尝试将文件从一个文件夹保存到另一个文件夹。zip 文件夹放置在不同的目录中。我写了以下代码：
存档.php
<?php
$zip = new ZipArchive();
$zip->open('example.zip', ZipArchive::CREATE);
$srcDir = "/home/sam/uploads/";
$files= scandir($srcDir);
//var_dump($files);
unset($files[0],$files[1]);
foreach ($files as $file) {
$zip->addFile("{$file}");
}
$zip->close();
?>
但遗憾的是我无法创建 .zip 文件夹。我错过了什么步骤吗？
$zip = new ZipArchive();
$DelFilePath="first.zip";
if(file_exists($_SERVER['DOCUMENT_ROOT']."/TEST/".$DelFilePath)) {
unlink ($_SERVER['DOCUMENT_ROOT']."/TEST/".$DelFilePath);
}
if ($zip->open($_SERVER['DOCUMENT_ROOT']."/TEST/".$DelFilePath, ZIPARCHIVE::CREATE) != TRUE) {
die ("Could not open archive");
}
$zip->addFile("file_path","file_name");
// close and save archive
$zip->close();
这里 TEST 是您的项目文件夹名称。
您可以根据需要定义路径。
是的，我已经解决了我的问题。
这里我刚刚替换了代码
$zip->addFile("{$file}");
用代码
$zip->addFromString(basename($file), file_get_contents($file));
并完成我的工作。:)
创建一个新的 zip 文件
$zip = new ZipArchive;
if ($zip->open('test_new.zip', ZipArchive::CREATE) === TRUE)
{
// Add files to the zip file
$zip->addFile('test.txt');
$zip->addFile('test.pdf');
// Add random.txt file to zip and rename it to newfile.txt
$zip->addFile('random.txt', 'newfile.txt');
// Add a file new.txt file to zip using the text specified
$zip->addFromString('new.txt', 'text to be added to the new.txt file');
// All files are added, so close the zip file.
$zip->close();
}
覆盖现有的 zip 文件
（使用 OVERWRITE 时，文件必须已经存在，如果不存在，则操作失败。）
$zip = new ZipArchive;
if ($zip->open('test_overwrite.zip', ZipArchive::OVERWRITE) === TRUE)
{
// Add file to the zip file
$zip->addFile('test.txt');
$zip->addFile('test.pdf');
// All files are added, so close the zip file.
$zip->close();
}
创建一个新的 zip 文件并将文件添加到文件夹中
$zip = new ZipArchive;
if ($zip->open('test_folder.zip', ZipArchive::CREATE) === TRUE)
{
// Add files to the zip file inside demo_folder
$zip->addFile('text.txt', 'demo_folder/test.txt');
$zip->addFile('test.pdf', 'demo_folder/test.pdf');
// Add random.txt file to zip and rename it to newfile.txt and store in demo_folder
$zip->addFile('random.txt', 'demo_folder/newfile.txt');
// Add a file demo_folder/new.txt file to zip using the text specified
$zip->addFromString('demo_folder/new.txt', 'text to be added to the new.txt file');
// All files are added, so close the zip file.
$zip->close();
}
创建一个新的 zip 文件并将文件移动到不同的文件夹中
$zip = new ZipArchive;
if ($zip->open('test_folder_change.zip', ZipArchive::CREATE) === TRUE)
{
// Add files to the zip file
$zip->addFile('text.txt', 'demo_folder/test.txt');
$zip->addFile('test.pdf', 'demo_folder1/test.pdf');
// All files are added, so close the zip file.
$zip->close();
}
使用目录中的所有文件创建一个 zip 文件
$zip = new ZipArchive;
if ($zip->open('test_dir.zip', ZipArchive::OVERWRITE) === TRUE)
{
if ($handle = opendir('demo_folder'))
{
// Add all files inside the directory
while (false !== ($entry = readdir($handle)))
{
if ($entry != "." && $entry != ".." && !is_dir('demo_folder/' . $entry))
{
$zip->addFile('demo_folder/' . $entry);
}
}
closedir($handle);
}
$zip->close();
}
将多个文件和目录添加到一个 zip 文件
$zip = new ZipArchive;
if ($zip->open('test_files_dirs.zip', ZipArchive::OVERWRITE) === TRUE)
{
// Add directory1
if ($handle = opendir('demo_folder/directory1/'))
{
while (false !== ($entry = readdir($handle)))
{
if ($entry != "." && $entry != "..")
{
$zip->addFile('demo_folder/directory1/' . $entry);
}
}
closedir($handle);
}
// Add directory2
if ($handle = opendir('demo_folder/directory2/'))
{
while (false !== ($entry = readdir($handle)))
{
if ($entry != "." && $entry != "..")
{
$zip->addFile('demo_folder/directory2/' . $entry);
}
}
closedir($handle);
}
// Add directory3
if ($handle = opendir('demo_folder/directory3/'))
{
while (false !== ($entry = readdir($handle)))
{
if ($entry != "." && $entry != "..")
{
$zip->addFile('demo_folder/directory3/' . $entry);
}
}
closedir($handle);
}
// Add more files
$zip->addFile('demo_folder/index.txt');
$zip->close();
}

试试这个代码：
$zip = new ZipArchive;
if ($zip->open(getcwd() . '/test.zip', ZipArchive::CREATE) === TRUE) {
$zip->addFile(getcwd() . '/file.txt', 'newname.txt');
$zip->close();
echo 'ok';
} else {
echo 'failed';
}
请看下面的例子：
<?php
$error = ""; //error holder
if(isset($_POST['createpdf'])){
$post = $_POST;
$file_folder = "files/"; // folder to load files
if(extension_loaded('zip')){ // Checking ZIP extension is available
if(isset($post['files']) and count($post['files']) > 0){ // Checking files are selected
$zip = new ZipArchive(); // Load zip library
$zip_name = time().".zip"; // Zip name
if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE){ // Opening zip file to load files
$error .= "* Sorry ZIP creation failed at this time<br/>";
}
foreach($post['files'] as $file){
$zip->addFile($file_folder.$file); // Adding files into zip
}
$zip->close();
if(file_exists($zip_name)){
// push to download the zip
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="'.$zip_name.'"');
readfile($zip_name);
// remove zip file is exists in temp path
unlink($zip_name);
}
}else
$error .= "* Please select file to zip <br/>";
}else
$error .= "* You dont have ZIP extension<br/>";
}
