Binary Stream
How to save back to a file.

One of my suppliers provides me with an XML file. This XML file contains a CDATA section with a binary stream of a zipped CSV file.

Once I've parsed the XML file and retrieved the Binary Stream, how do I save it back to a ZIP file?

You open a file for writing (binary if you're on wintendo), write to it and close it.

fopen: [php.net...]
fwrite: [php.net...]
fclose: [php.net...]

Try it, if you fail to get the result, show relevant code.

Hi Swa66

I tried that and it doesn't work. Here is what is says in the manual

"The response object of this method will return you a binary stream which you
will need to create a zip file out of"

And here is the XML response

<stream>UEsDBBQAAAAIANaTPkKNE32Qcx4AAKHcAAAQACQAUHJvZEZlZWRGaWxlLnhtbAoAIAAAAAAAAQAYAJ7BnOoX/80BnsGc6hf/zQGewZzqF.......</stream>

I parse the XML storing the stream in $response

$file=fopen("/filepath/test.zip","wb");
fwrite($file,$response);
fclose($file);


The zip file gets created as expected, however when I try opening it, it gives an error. "Not a valid ZIP file"

Your stream looks not to be binary. I'd guess it to be base64 encoded.

php has what you need to decode base64 (assuming it is base64) [php.net...]

Thank you swa66

base64_decode($response);

Was the solution.
