在 PHP 中修改 ZIP 文件中的单个文本文件 [英] Modifying a single text file in a ZIP file, in PHP

问题描述

我的服务器上有一个 ZIP 文件.我想创建一个接受单个参数的 PHP 文件 loadZIP.php，然后修改 ZIP 中的一个文本文件以反映该参数.

I have a ZIP file on my server. I want to create a PHP file, loadZIP.php that will accept a single parameter, and then modify a text file within the ZIP to reflect that parameter.

因此，访问 loadZIP.php?param=blue，将打开 zip 文件，并将我指定的文本文件中的一些文本替换为blue"，并允许用户下载此文件已编辑的 zip 文件.

So, accessing loadZIP.php?param=blue, will open up the zip file, and replace some text in a text file I specify with 'blue', and allow the user to download this edited zip file.

我查看了所有 PHP ZIP 函数，但找不到简单的解决方案.这似乎是一个相对容易的问题，我相信我想多了.在我开始编写一些过于复杂的函数之前，我想知道你会怎么做.

I've looked over all of the PHP ZIP functions, but I can't find a simple solution. It seems like a relatively easy problem, and I believe I'm over thinking it. Before I go and write some overly complex functions, I was wondering how you'd go about this.

推荐答案

你看过 PHP5 的 ZipArchive 函数吗?

Have you taken a look at PHP5's ZipArchive functions?

基本上，您可以使用 ZipArchive::Open() 打开 zip，然后 ZipArchive::getFromName() 将文件读入内存.然后，修改它，使用 ZipArchive::deleteName() 删除旧文件，使用 ZipArchive::AddFromString() 将新内容写回 zip，并且 ZipArchive::close():

Basically, you can use ZipArchive::Open() to open the zip, then ZipArchive::getFromName() to read the file into memory. Then, modify it, use ZipArchive::deleteName() to remove the old file, use ZipArchive::AddFromString() to write the new contents back to the zip, and ZipArchive::close():

$zip = new ZipArchive;
$fileToModify = 'myfile.txt';
if ($zip->open('test1.zip') === TRUE) {
    //Read contents into memory
    $oldContents = $zip->getFromName($fileToModify);
    //Modify contents:
    $newContents = str_replace('key', $_GET['param'], $oldContents)
    //Delete the old...
    $zip->deleteName($fileToModify)
    //Write the new...
    $zip->addFromString($fileToModify, $newContents);
    //And write back to the filesystem.
    $zip->close();
    echo 'ok';
} else {
    echo 'failed';
}

注意 ZipArchive 是在 PHP 5.2.0 中引入的(但是，ZipArchive 也可用作 PECL 包).

Note ZipArchive was introduced in PHP 5.2.0 (but, ZipArchive is also available as a PECL package).
