Compress base64 string in python and extract it in PHP

Question

I'm sending a base64 string compressed with zlib in Python, converted to base64, sent to a PHP page where it will be extracted.

I'm having trouble with this. How would I do this?

Right now I have:

python

compressor = zlib.compressobj(wbits=(16+zlib.MAX_WBITS))
compressed = compressor.compress(str)
compressed += compressor.flush()

php

*POST deccoded here, b64data is the output*
$b64data = zlib_decode($data);

I left out the part where I decode from base64. The php code throws and error about invalid data at the zlib function. zlib_decode(): data error

Answer 1

Ok, I messed up and the problem wasn't with the zlib function.

Long story short I used to encode the data twice on the Python side but changed it to only encode once and never removed the extra base64_decode from the PHP.

Thanks for the help guys.
