Description:
------------
When running my script under *suexec'd* php, the POST variables are not populated. GET is populated OK. When running via apache module, POST vars are OK.

My cgi script is go.cgi, with #!/usr/bin/php at the top, POSTs a form back to itself. Nothing fancy.

php is 4.3.4, apache is 1.3.29

If I write a C program, that outputs stdin, and set the #! line of go.cgi to this program, then the correct POST data is output (myinput=what_i_typed) running under suexec.

If I go back to using #!/usr/bin/php, and read stdin then I get nothing.
Examining the environment ($_ENV) the CONTENT_LENGTH env var is set correctly, the more I type the bigger it gets. Also REQUEST_METHOD=POST. Just no _POST vars.

Changing the form to use GET works fine (via _GET)

All this is on a VirtualHost'd server.

Any ideas???!

Mike
