PHP Partial Zip 允许您下载位于远程ZIP文件内的文件。

使用方法

composer require stnvh/php-partialzip 0.2.x

方法使用

__construct($url, $file = false)

类初始化方法

$p = new Partial('http://some.site.com/cats.zip');

index()

返回远程目录中所有文件的列表

/*...*/

$list = $p->index(); # = ('cat.png', 'cat2.png', 'cat3.png')

find($fileName = false)

返回用于获取远程文件的解析文件对象

/*...*/

# Search and return other file objects
if($file = $p->find('cat2.png')) {
	# You can call methods here to fetch ZIP header information too
	# The full list of file header properties can be found in CDFile.php
	$size = $file->size(); # size in bytes
	$fullName = $file->name(); # full file name in zip, including path
}

get($file)

返回或输出从远程ZIP文件获取的文件。

注意：在echo ->get()之前，您应确保没有输出内容，因为这会导致文件下载包含无效数据。提示：在脚本开始时使用ob_start()，然后在输出之前运行ob_clean()。

/*...*/

if($file = $p->find('cat3.png')) {
    $fileData = $p->get($file);
}

示例

<?php

require 'vendor/autoload.php';

use Stnvh\Partial\Zip as Partial;

ob_start(); # will capture all output

$p = new Partial('http://some.site.com/cats.zip');

# Get file object
if($file = $p->find('cat.png')) {
	# removes everything from current output to ensure file downloads correctly
    ob_clean();

    # Set appropriate headers and output to browser:
	header(sprintf('Content-Disposition: attachment; filename="%s"', $file->filename));
	header(sprintf('Content-Length: %d', $file->size));

    echo $p->get($file);
}
