However, $mode 'wb' is supossed to enable binary mode, and it does so for me (it is important to write that as 'wb', not as 'bw' or 'w b' etc.) Since you can no longer reproduce the problem with 'wb', I'm changing to documentation bug. Please open a new ticket, if you ever stumble upon 'wb' prepending 0x0D to any 0x0A bytes. ------------------------------------------------------------------------ [2020-10-26 21:58:29] vanherkmarcel at gmail dot com Hi, Thanks for trying. I lost my test code, since I programmed around it. My exe is the CGI interface of a DICOM server (Conquest DICOM server), and I was using php to forward a POST request to is CGI client dgate.exe. By default popen($exe, "w") opens in text mode on Windows - this is not documented. popen($exe, "wb") is not documented either, and when I tried it did seem not start my exe. There may have been a mixup with PHP versions though.

Is there some error message? Which executable do you call? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
