Gzinflate on a string that has been base_64 encoded in Windows

Greetings! I have a long piece of string that is apparently a PNG image which has been base_64 decoded in an XML file. I can retreive this string without problem. The string is in $mystra $pngdata = base64_decode($mystra); $pngdata = gzinflate($pngdata); When i try to gzinflate it , i get a warning that says "data error" and if i write pngdata to a binary file using fopen, there is 0 bytes (because of the warning). If i just write the base_64 decoded data to a binary file, then I can't open the file as a gziped file. (it is not a valid gzip'ed file) From the person who sent me the XML file, what I was told the base_64 decoded data will give me the deflated binary array for the image, which I would need to inflate using an InflaterInputStream, and as a result, I will get the PNG file that is represented in $mystra. I probably need to add some PNG headers to it and/or explode the base_64 decoded data and then add headers to it. I am getting quite lost here. Can anyone provide some hints please? Regards Venky
