Running latest php4 CVS as CGI, Apache 1.3.20, no modules

A similar bug was reported in the past (#9041, #8898, #8782) but I'm running the latest CVS.

The following modification seemed to do the trick:

Cannot reproduce this:

$ cat test.php 
#!/home/mfischer/php4/bin/php -q
<?
  echo "test\n";
?>

mfischer@debian:~$ ./test.php 
test
mfischer@debian:~$ php -f test.php 
test

Nope, this bug only shows up if you run it through CGI. Running from the command-line works fine.

Sounds like a misconfiguration to me.

Err ... whats the point of using this in a CGI?

I understand, some kind of portability probably (running it from CMD and CGI) but this is some dirty magic stuff IMHO. 

Its just a text file which gets processed and when it starts with #! then it starts with #! and therefore the output shall be #!.

However, I've an open mind for that :)

No, the point is if you run a script as a conventional CGI-script (just like you can run shell scripts through CGI), the line with #!/path/to/php shows up...
Normally, if you run PHP as CGI via Apache, some lines in httpd.conf say that *.php should be parsed through /usr/local/bin/php
It's not necessary to use that. Alternatively, you could use #!/path/to/php if the server has (plain) CGI enabled. It's usefull i.e. if you have built a dev-version of PHP somewhere and don't want to install it, but just use it for a few scripts to test new functionality.

And about magic stuff: the patch which hides #! when running via the command line, has already been commited... isn't that magic too?


Workaround: enable output buffering in your php.ini and start your scripts with ob_end_clean();.
