如何從PHP中的Base64Binary編碼數據獲取原始數據？

我正在使用Salesforce元數據API。我正在創建一個base64數據，其中包含一個項目清單，一個名爲package.xml的文件。如何從這些數據中獲取package.xml文件。如何從PHP中的Base64Binary編碼數據獲取原始數據？

請參考下面的編碼數據：

這看起來像一個zip文件可能。 – Musa

我想你會得到正確的解碼字符串。它看起來像一個壓縮或加密的文件。 –

我試過這段代碼：

<?php 
header('Content-Type: application/zip'); 
header('Content-disposition: filename="my.zip"'); 
$s = "UEsDBBQACAAIAOcycUEAAAAAAAAAAAAAAAAhAAAAdW5wYWNrYWdlZC9vYmplY3RzL0NvbnRhY3Qub2JqZWN01Vffb9owEH7nr4jyPpxO0zRNIRWlVKDxS5CNR2SSC/FwHGo7tPnv65CAE0CoUFYxnnKfz+fvvrtLjH3/GlFjDVyQmDXMu7plGsC82Cds0TB/u09ffpj3Ts1uJULG0XD+FzxpqC1MNMxQytVPhESMV3URxNyDuhdH6KtlfUfWNxSBxD6W2HRqhvrZwPCcwhOALxzJE7BRGcl9AgJ0a+RAQukAR+D0MFskeAFiNvNstIO1J7xK4AzTru8EmIosvEa0G8VzoDqajXKg5ABsIUPnzrLUWv6sFzk8J4TD7oidrV0kx94yy6lDlGQ83boe4KUt6QocV9FVXtmjXkkYeU5gG6KwcqlQWatTwgH2J3GiqnNUthXxllQx0lAF/oNpAqK6WI0/hfmxwDtHHwKcULnNYWtWj0OnzjuDzCiMGRhdllUlvSFamEsG3BhDAJxjekPMVGOEWIBv9JT/7fAayhD4v6YjYi71LBdW7XDz/qiOCrw8rmfM4xrodV5iWaTDF9iHJ3oCXsx8fEsD5AKX5KYYjTiJPoHQJS164QfoHV29oUng5WhjNyltxUxiT4qjvR0Qqlp54sUqeFvdOFIZqktGdoLG91tcxTR00FKnK6PK5TS3B8Jl6ONUuCERfRUwvALFHN2v2EYwpzUcuM2WW3/ojt3OY9NtF0ruOauAHEt19XLURUKVyUYaqXqus+5w3E53Muur2B0b5UipFw74FCLukjey7I0i/cvF7KfvrnOfMDhd4X56lQIP4KWHhZwCLD+psq1xW5X1cXa94vaaE3c2bbd/nVFblbeRJW7kmX9IwKw7/msBN9NxgYCbsTgtoI3K/4Cc2htQSwcIRtMK5HUCAAA4DQAAUEsDBBQACAAIAOcycUEAAAAAAAAAAAAAAAAWAAAAdW5wYWNrYWdlZC9wYWNrYWdlLnhtbE2OzQrCMBCE732KkLvZWKSIpOmh4FUP+gBpumrVJKVZRd/e2h90TzPDx+yo4uXu7IldbILP+VJIztDbUDf+nPPjYbtY80Inam/szZyR9bSPOb8QtRuAGEwr4il0FoUNDlIpM5ArcEimNmS4Tlh/it4txlEP3qGr+pe6DJ6MJQVz8EO8cajLR6TgdtUVv9AQjYXw16im9TrNhFQwu0TBNFonH1BLBwj45N4QogAAAOYAAABQSwECFAAUAAgACADnMnFBRtMK5HUCAAA4DQAAIQAAAAAAAAAAAAAAAAAAAAAAdW5wYWNrYWdlZC9vYmplY3RzL0NvbnRhY3Qub2JqZWN0UEsBAhQAFAAIAAgA5zJxQfjk3hCiAAAA5gAAABYAAAAAAAAAAAAAAAAAxAIAAHVucGFja2FnZWQvcGFja2FnZS54bWxQSwUGAAAAAAIAAgCTAAAAqgMAAAAA"; 
$out = base64_decode($s); 
print($out); 
?>

然後瀏覽器下載一個包含.xml文件的工作ZIP文件。

如果你想處理使用的PHP ZIP文件的內容，您可以啓用php_zip延伸，並檢查了這樣的回答：Unzip a file with php

謝謝。我嘗試了相同的代碼，但它正在下載php文件本身，而不是一個zip文件 – user1808669

我正在使用Xampp localhost。該文件名的擴展名爲.php，即WinRAR ZIP壓縮文件（1.1 kB）。下載完成後，雙擊它，它會在editot中打開一些特殊的charectors loke PK [] [] [] – user1808669

下載該文件，將其重命名爲.zip並用解壓縮軟件打開它（或Windows內置的東西）。你也可以添加這個PHP代碼來強制文件名：'header（'Content-disposition：filename =「my.zip」'）;' –
