PHP 批量打包下载文件

需求描述:

有数个文件,包含图片,文档。需要根据条件自动打包成压缩包,提供下载。

解决(ZipArchive 类):

PHP提供了ZipArchive 类可为我们实现这一功能,demo:

<?php

$files = array('image.jpeg','text.txt','music.wav');
$zipname = 'enter_any_name_for_the_zipped_file.zip';
$zip = new ZipArchive;
$zip->open($zipname, ZipArchive::CREATE);
foreach ($files as $file) {
$zip->addFile($file);
}
$zip->close();

///Then download the zipped file.
header('Content-Type: application/zip');
header('Content-disposition: attachment; filename='.$zipname);
header('Content-Length: ' . filesize($zipname));
readfile($zipname);

?>

ThinkPHP版

$zip = new \ZipArchive;
//压缩文件名
$filename = 'download.zip';
//新建zip压缩包
$zip->open($filename,\ZipArchive::OVERWRITE);
//把图片一张一张加进去压缩
foreach ($images as $key => $value) {
$zip->addFile($value);
}
//打包zip
$zip->close();

//可以直接重定向下载
header('Location:'.$filename);

//或者输出下载
header("Cache-Control: public"); 
header("Content-Description: File Transfer"); 
header('Content-disposition: attachment; filename='.basename($filename)); //文件名 
header("Content-Type: application/force-download");
header("Content-Transfer-Encoding: binary");
header('Content-Length: '. filesize($filename)); //告诉浏览器,文件大小 
readfile($filename);

区别在引用的时候路径要对,结束。
