PHP：如何将GZ解压缩为字符串？

Question

I need to retrieve a GZ compressed XML file from a remote server and parse it via simplexml_load_string. Is there a way to do this without uncompressing the GZ to a file, then reading that file via simplexml_load_file? I want to skip what seems like an unnecessary step to me.

Answer 1

You should be able to do it with the gzdecode function from the Zlib library.

$uncompressedXML = gzdecode(file_get_contents($url));

More about gzdecode() from the PHP Docs.

However, there is even an easier way, and it's by using a compression wrapper.

$uncompressedXML= file_get_contents("compress.zlib://{$url}");

Or even better:

$xmlObject=simplexml_load_file("compress.zlib://{$url}");

Don't forget to install and enable Zlib on your development/production server.
