如何从PHP中的Base64Binary编码数据获取原始数据？

我正在使用Salesforce元数据API。我正在创建一个base64数据，其中包含一个项目清单，一个名为package.xml的文件。如何从这些数据中获取package.xml文件。如何从PHP中的Base64Binary编码数据获取原始数据？

请参考下面的编码数据：

这看起来像一个zip文件可能。 – Musa

我想你会得到正确的解码字符串。它看起来像一个压缩或加密的文件。 –

我试过这段代码：

<?php 
header('Content-Type: application/zip'); 
header('Content-disposition: filename="my.zip"'); 
$s = "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"; 
$out = base64_decode($s); 
print($out); 
?>

然后浏览器下载一个包含.xml文件的工作ZIP文件。

如果你想处理使用的PHP ZIP文件的内容，您可以启用php_zip延伸，并检查了这样的回答：Unzip a file with php

谢谢。我尝试了相同的代码，但它正在下载php文件本身，而不是一个zip文件 – user1808669

我正在使用Xampp localhost。该文件名的扩展名为.php，即WinRAR ZIP压缩文件（1.1 kB）。下载完成后，双击它，它会在editot中打开一些特殊的charectors loke PK [] [] [] – user1808669

下载该文件，将其重命名为.zip并用解压缩软件打开它（或Windows内置的东西）。你也可以添加这个PHP代码来强制文件名：'header（'Content-disposition：filename =“my.zip”'）;' –
