Edit report at https://bugs.php.net/bug.php?id=80282&edit=1 ID: 80282 User updated by: vanherkmarcel at gmail dot com Reported by: vanherkmarcel at gmail dot com Summary: cannot send binary data to popen -Status: Feedback +Status: Assigned Type: Bug Package: Filesystem function related Operating System: Windows PHP Version: 7.4.11 Assigned To: cmb Block user comment: N Private report: N New Comment: 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.

What exactly fails? Is there some error message?
