Creating .zip file
提问by Sam
I am trying to save filesfrom one folderto another. zip folderplaced in different directory. And I have written the following codes:
我正在尝试将文件从一个文件夹保存到另一个文件夹。zip 文件夹放在不同的目录中。我写了以下代码：
archive.php
档案.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();
?>
But sadly I am not able to create the .zip folder. Is there any step I missed?
但遗憾的是我无法创建 .zip 文件夹。有没有我遗漏的步骤？

$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();
Here TEST is your project folder name.
这里 TEST 是您的项目文件夹名称。
You can define path as you want.
您可以根据需要定义路径。

Please see this below example:
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/>";
}
?>
